milan-berri	7270f723de	fix(mcp): forward upstream initialize instructions on cold gateway init (#28231) ... Prefetch upstream InitializeResult.instructions before merging gateway initialize options when YAML/DB do not set instructions, so clients receive upstream server text on the first MCP initialize without list_tools.

Sameer Kankute	f35e7eb2f6	feat(guardrails): add Microsoft Purview DLP guardrail (#24966) ... * feat(guardrails): add Microsoft Purview DLP guardrail * fix(guardrails/purview): raise_for_status on HTTP errors, cap scope cache, reuse executor * fix(guardrails/purview): propagate litellm_call_id as correlation_id to Purview * chore: fixes * refactor(guardrails): delegate get_user_prompt to get_last_user_message PurviewGuardrailBase duplicated AzureGuardrailBase (and OpenAIGuardrailBase) user-prompt extraction. The same logic already lived in common_utils.get_last_user_message; wire guardrail bases to that helper, fix the helper docstring, and drop its redundant self-import of convert_content_list_to_str. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(purview): make protection scope cache true LRU on hits OrderedDict.get() does not update insertion order; call move_to_end on TTL-valid cache hits so popitem(last=False) evicts least-recently-used users instead of FIFO by first insert. Add a regression test with a small max cache size. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * Fix mypy * fix(guardrails/purview): harden user-id resolution and broaden DLP text Prefer API key and proxy-injected metadata over client metadata for Entra identity. Scan full message transcript pre-call and all completion choices post-call. Align logging-only hook with the same user-id rules. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(guardrails/purview): scan /v1/completions prompt and TextChoices Normalize text-completion prompts (string or list of strings); skip token-id-only prompts. Run post-call DLP on TextCompletionResponse choices. Extend logging_only hook for text_completion. Add tests and completion_prompt_to_str helper. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(purview-dlp): return data after DLP pass; per-call executor; dedupe text extraction async_pre_call_hook now returns the request dict after a successful check so callers match skip-path behavior. logging_hook uses a fresh ThreadPoolExecutor per invocation like Presidio to avoid single-worker starvation. Response text extraction is centralized in _completion_response_text_parts. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(purview): fix LRU cache refresh position and add Responses API scanning Two fixes to the Microsoft Purview DLP guardrail: 1. LRU cache bug (base.py): When a stale scope cache entry was re-fetched, the assignment updated the value but Python's OrderedDict.__setitem__ preserves the original insertion order for existing keys. This left the refreshed entry near the front of the dict, making it the first candidate for LRU eviction via popitem(last=False). Fix: call move_to_end(user_id) after every write to an existing key. 2. Responses API coverage gap (purview_dlp.py): Requests to /v1/responses use an 'input' field instead of 'messages' or 'prompt', so the pre-call hook returned without scanning the content. Similarly, post-call hook did not handle ResponsesAPIResponse.output. Fix: add _responses_api_input_to_str() helper and handle 'responses'/'aresponses' call types in async_pre_call_hook, async_post_call_success_hook (via _completion_response_text_parts), and async_logging_hook. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(purview): message separator, non-blocking logging_hook, TextChoices type error Three bugs fixed in the Microsoft Purview DLP guardrail: 1. get_prompt_text_for_dlp message separator (base.py) - Previously called get_str_from_messages() which concatenated all message texts with NO separator, so 'end of msg1' + 'start of msg2' became 'end of msg1start of msg2'. - Now joins per-message text with '\n\n' via convert_content_list_to_str(), preserving DLP pattern detection accuracy across message boundaries. 2. logging_hook blocking the event loop thread (purview_dlp.py) - Previously called future.result() which blocked the calling thread (often the event loop thread) for the entire round-trip of two sequential Microsoft Graph API calls (_compute_protection_scopes + _process_content). - Now fires and forgets: when called inside a running loop, schedules the coroutine with loop.create_task(); otherwise spawns a daemon thread. Returns (kwargs, result) immediately in both cases. - Removes unused concurrent.futures.ThreadPoolExecutor import; adds threading. 3. Incompatible assignment type error (purview_dlp.py:180) - mypy inferred 'choice' as TextChoices from the first loop body, then flagged the assignment in the second loop as incompatible with Choices. - Fixed by using distinct loop variable names: text_choice (TextChoices) and chat_choice (Choices). Tests: 7 new tests added covering the separator fix (TestGetPromptTextForDlp) and the non-blocking logging_hook (TestLoggingHookNonBlocking). Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(purview): suppress API errors in logging-only mode and scan tool-call arguments Three issues fixed: 1. _check_content except block re-raised unconditionally even when block_on_violation=False. The docstring promised 'log only - do not raise' but network/API errors always propagated. Fixed by checking block_on_violation before re-raising; when False, log a warning and continue. 2. async_logging_hook used a single try/except wrapping both the prompt and response audit calls. When the first _check_content (uploadText) raised due to an API error the second call (downloadText) was silently skipped. Fixed by giving each audit call its own try/except so both always run independently. 3. convert_content_list_to_str() only reads message.content, so tool_calls[].function.arguments and function_call.arguments were invisible to the Purview pre-call and post-call scans. An authenticated caller could embed sensitive text in tool-call arguments and bypass DLP. Fixed by: - Adding PurviewGuardrailBase._extract_tool_call_args_from_message() which handles both dict and object-style messages, covering both tool_calls[] arrays and the legacy function_call field. - Updating get_prompt_text_for_dlp() to include those arguments alongside message content (request/prompt path). - Changing _completion_response_text_parts() from @staticmethod to an instance method and adding tool-call argument extraction for ModelResponse choices (response path). Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * chore(ui): restructure pre-built Next.js output to directory-based routing Flat page files (e.g. guardrails.html) replaced by directory-based index.html equivalents (e.g. guardrails/index.html) matching the Next.js App Router output format. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(purview): comprehensive security hardening — identity spoofing, streaming bypass, token-id gap Four security issues addressed: 1. end_user_id kwargs fallback missing in _resolve_user_id_from_logging_kwargs user_id already fell back to kwargs.get("user_api_key_user_id") when absent from metadata, but end_user_id only checked md.get("user_api_key_end_user_id") with no kwargs-level fallback. Added or kwargs.get("user_api_key_end_user_id"). 2. Streaming responses bypassed post_call blocking async_post_call_success_hook only runs on assembled non-streaming responses. For streaming requests the proxy already delivered all content before the hook ran, so raising HTTPException there had no effect. Added async_post_call_streaming_iterator_hook which buffers the entire stream, assembles it via stream_chunk_builder, runs the Purview DLP check, and only then re-yields chunks via MockResponseIterator. If a violation is detected the exception is raised before any bytes reach the client. The proxy automatically skips async_post_call_success_hook for guardrails that define this method, preventing duplicate scans. 3. Caller-controlled Purview user identity in blocking modes When a LiteLLM API key has no bound user_id the guardrail fell back to metadata[user_id_field], which is supplied by the caller. A caller could set this to any Entra object ID whose Purview policies are more permissive and bypass DLP. Added _resolve_trusted_user_id() that only returns identities from the proxy auth system (user_api_key_dict.user_id, end_user_id, or proxy-injected metadata["user_api_key_user_id"]). Added _resolve_user_id_for_blocking() used by all blocking-mode hooks: tries trusted sources first; if only caller-supplied is available, logs a SECURITY WARNING and still proceeds (backward compat); if nothing resolves, skips with a warning. 4. Token-id prompt DLP bypass When /v1/completions received a pure token-id array prompt, completion_prompt_to_str() returned None and the pre_call hook silently skipped the Purview scan. An authenticated caller could tokenize blocked text and send it without DLP evaluation. The hook now detects this case (raw_prompt present but prompt_text None) and logs a WARNING while letting the request pass through — token-id payloads are opaque at the text layer and cannot be scanned. This makes the gap explicit rather than silent. Tests: 94 total, all passing. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * Revert "chore(ui): restructure pre-built Next.js output to directory-based routing" This reverts commit c70c4303b7. * fix(purview): fail closed on identity spoofing, token prompts, and path encoding Encode Entra user IDs in Graph paths, guard caches with asyncio.Lock, scan Responses API instructions with string input, reject caller-only metadata and token-id completion prompts in blocking mode, and revert unrelated UI HTML restructure from the PR branch. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(purview): use threading.Lock and getattr for LitellmParams - Replace asyncio.Lock with threading.Lock in PurviewGuardrailBase. The cache lock is acquired both from the proxy's main event loop and from short-lived event loops created by the logging_hook thread fallback. In Python 3.10+ an asyncio.Lock is bound to the first event loop that acquires it, so the second loop would silently break audit logging with RuntimeError. All critical sections are in-memory dict ops with no awaits, so a synchronous lock is safe. - Use getattr() on LitellmParams in initialize_guardrail() instead of .get(), which does not exist on Pydantic BaseModel instances and would raise AttributeError at runtime. Tests updated to construct Mock objects with spec= so they reflect the real interface. Co-authored-by: Yassin Kortam <yassin@berri.ai> * refactor(purview): dedupe trust-level user resolution and drop dead code - _resolve_user_id now delegates levels 1-3 to _resolve_trusted_user_id so blocking and non-blocking paths share a single source of truth. - Drop redundant event_hook override in MicrosoftPurviewDLPGuardrail.__init__ (initialize_guardrail already forwards event_hook=litellm_params.mode). - Drop unused self._logging_only attribute; blocking is controlled by the block_on_violation argument passed to _check_content. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview): fail-closed on responses API transform error; avoid duplicate audit calls Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview): fail-closed blocking DLP; revert directory-based UI HTML Blocking hooks now require UserAPIKeyAuth user_id/end_user_id only (no spoofable metadata), re-raise Responses API transform errors, scan streamed text completions, and reject requests with no bound identity. Reverts the accidental directory-based Next.js output from cc47081 (c70c4303b7). Co-authored-by: Cursor <cursoragent@cursor.com> * Remove dead code in purview_dlp: _resolve_user_id_for_blocking never returns falsy The method either returns a non-empty trusted user id or raises HTTPException, so the 'if not user_id' guards in async_pre_call_hook and async_post_call_success_hook were unreachable. Tighten the return type to str and drop the dead checks to make the fail-closed behavior explicit. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview): exclude caller-controlled end_user_id from blocking DLP Blocking Purview checks now use only API-key/JWT-bound user_id, not end_user_id populated from request user/metadata/safety_identifier. Co-authored-by: Cursor <cursoragent@cursor.com> * style(purview): apply Black formatting to base.py Co-authored-by: Cursor <cursoragent@cursor.com> * fix(purview): use post-await timestamp for cache TTL Capture the timestamp after the network call completes when storing it as the cache freshness marker, so the effective TTL reflects when the response was actually received rather than when the request started. Under high network latency the previous behavior shortened the effective cache lifetime. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): fail closed when stream_chunk_builder returns None stream_chunk_builder can return None (e.g., when ChunkProcessor filters all chunks), causing both isinstance checks to fail and the buffered chunks to be released without DLP scanning. Explicitly fail closed in that case by raising an HTTPException so the streaming DLP guardrail does not bypass policy enforcement. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): resolve user_id before buffering stream Co-authored-by: Yassin Kortam <yassin@berri.ai> * merge main (#28629) * test(vcr): classify cache verdicts, detect live calls, surface cost leaks Convert the per-test VCR verdict line from a single 'NOOP / HIT / MISS / PARTIAL' tag into a classified outcome that distinguishes the cases that silently bill the live API on every CI run from the ones that don't: HIT pure replay PARTIAL mixed replay + new recordings MISS:RECORDED new cassette saved to Redis (cached next run) MISS:OVERFLOW cassette > MAX_EPISODES_PER_CASSETTE; persister refused to save; re-bills every run MISS:NOT_PERSISTED test failed; save_cassette skipped; re-bills NOOP VCR-marked but no HTTP traffic (mocked elsewhere) UNMARKED:LIVE_CALL test bypassed VCR AND opened a TCP connection to a known LLM provider host -> wasted spend UNMARKED:NO_TRAFFIC test bypassed VCR but didn't call out The UNMARKED:LIVE_CALL signal is what converts 'this test probably hits live' into 'this test connected to api.openai.com'. We install a socket.connect / socket.create_connection wrapper for the duration of each non-VCR-marked test and record any outbound TCP to a known LLM provider hostname. The probe sits below the httpx layer so vcrpy and respx (which both patch above the socket) are unaffected. Replace the file-level _RESPX_CONFLICTING_FILES blacklists in the llm_translation and local_testing conftests with per-item respx detection in apply_vcr_auto_marker_to_items. A test now skips VCR when it actually carries @pytest.mark.respx or has respx_mock in its fixture chain - not just because some other test in the same file imports MockRouter. Items skipped by skip_files are split into respx_conflict (real conflict, the module wires up respx) vs file_opt_out (dead skip- list entry whose module never touches respx) so the session summary makes pruning obvious. Stabilize the AWS SigV4 fingerprint: the Authorization header on Bedrock requests rotates its Credential date and Signature on every call, which previously pushed every Bedrock test past the 50-episode overflow threshold. Extract the access-key id only ('aws-sigv4:AKIA...') so two requests with the same identity match. Always emit verdict logging when VCR is active (set LITELLM_VCR_VERBOSE=0 to opt back into the legacy quiet mode). Add a session-end classification summary that lists overflow tests, unmarked live-call tests, and the skip-reason breakdown. Wire the live-call probe + summary hook into every test directory that already uses the Redis-backed VCR cache (audio_tests, guardrails_tests, image_gen_tests, litellm_utils_tests, llm_responses_api_testing, llm_translation, local_testing, logging_callback_tests, ocr_tests, pass_through_unit_tests, router_unit_tests, search_tests, unified_google_tests). Add tests/llm_translation/test_vcr_classification.py covering the verdict classifier, skip-reason tagging, AWS SigV4 fingerprint stability, live-host classification, and session summary rendering. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * test(vcr): drop dead 'from respx import MockRouter' imports These seven test files were on _RESPX_CONFLICTING_FILES, which made the auto-marker skip them entirely. Inspecting the source shows the only respx artifact is a top-level 'from respx import MockRouter' that no test ever uses - no @pytest.mark.respx, no respx_mock fixture, no respx.mock context manager. The import is dead code left over from a previous mocking pattern. Now that apply_vcr_auto_marker_to_items detects respx per-item via the marker / fixture chain (b637d9f64a), the file-level skip is no longer needed for these files - they were the reason the OpenAI tests (test_o3_reasoning_effort, test_streaming_response[o1/o3-mini], TestOpenAIO1::test_streaming, TestOpenAIChatCompletion::test_web_search, TestOpenAIO3::test_web_search, etc.) ran live every CI build despite the cassette cache being healthy. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * test(image_edits): regenerate fixtures per call instead of holding open module-level file handles Module-level TEST_IMAGES = [ open(os.path.join(pwd, 'ishaan_github.png'), 'rb'), open(os.path.join(pwd, 'litellm_site.png'), 'rb'), ] SINGLE_TEST_IMAGE = open(...) opens the file once at import. After the first multipart upload, the file pointer is at EOF, so every subsequent test in the same xdist worker sends an empty multipart body. That non-determinism (a) blows the recorded cassette past MAX_EPISODES_PER_CASSETTE (50) so _RedisPersister.save_cassette refuses to save it, and (b) re-bills the live image edit endpoint on every CI run. Recent CI runs confirm the leak: tests/image_gen_tests/test_image_edits.py shows six tests parking at 51-52 cassette entries (TestOpenAIImageEditGPTImage1::test_openai_image_edit_litellm_sdk[False], TestOpenAIImageEditDallE2::..., test_openai_image_edit_with_bytesio, test_openai_image_edit_litellm_router, test_multiple_vs_single_image_edit[False], test_multiple_image_edit_with_different_formats). Replace the module-level file handles with _make_test_images() / _make_single_test_image() factories that return fresh _RewindableImage (BytesIO subclass) objects whose pointer always starts at 0. The image bytes are read once at import into module-level constants (_ISHAAN_GITHUB_BYTES, _LITELLM_SITE_BYTES), so disk I/O cost is unchanged. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(vcr): match real Bedrock hostnames in live-call probe The suffix '.bedrock-runtime.amazonaws.com' never matched real Bedrock endpoints, which use the format 'bedrock-runtime[-fips].{region}.amazonaws.com' (region between 'bedrock-runtime' and 'amazonaws.com'). Add an explicit host check for that pattern so Bedrock live calls are visible to the probe, and update the unit test accordingly. Also drop the unused '_LIVE_CALL_PROBE_INSTALLED' module variable. * fix(vcr): cover full RFC1918 172.16.0.0/12 range in local prefixes * fix(image_edits): drop _RewindableImage to prevent infinite multipart upload The _RewindableImage(BytesIO) wrapper auto-rewound on every read after EOF, which made the OpenAI SDK's multipart upload writer read the same bytes forever instead of seeing EOF. Workers OOM'd / SIGKILL'd: [gw0] node down: Not properly terminated replacing crashed worker gw0 ... worker 'gw1' crashed while running 'tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditGPTImage1::test_openai_image_edit_litellm_sdk[False]' The auto-rewind was added defensively for parametrized + flaky-retried tests, but BaseLLMImageEditTest::test_openai_image_edit_litellm_sdk already calls get_base_image_edit_call_args() once per invocation and that helper now constructs fresh streams via _make_test_images(), so rewinding inside the stream is unnecessary. Replace with plain BytesIO seeded with the cached image bytes. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * test(vcr): mark Bedrock prompt-caching cross-call tests VCR-incompatible The pass_through prompt-caching tests (test_prompt_caching_returns_cache_read_tokens_on_second_call, test_prompt_caching_streaming_second_call_returns_cache_read) make a warm-up call and then assert the *second* call sees a non-zero cache_read_input_tokens count from the upstream's prompt-cache. VCR replay can't model cross-call provider state — both calls match the same cassette episode, so the second call returns the first call's pre-warmup response and the assertion fails: AssertionError: Expected cache_read_input_tokens > 0 on second call, but got 0. Full usage: {'input_tokens': 4986, 'cache_creation_input_tokens': 4974, 'cache_read_input_tokens': 0} This started biting after the AWS SigV4 fingerprint stabilization (b637d9f64a): Bedrock requests now produce a stable per-access-key fingerprint instead of a per-request signature, so cassettes successfully replay where they previously always missed and re-recorded live. Opt these tests out via skip_nodeid_suffixes so they run live and match the existing pattern in tests/llm_translation/conftest.py (::test_prompt_caching). Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * test(vcr): tighten OVERFLOW classification and switch respx detection to AST Address two greptile P2 review concerns on PR #27795: 1. MISS:OVERFLOW was firing whenever total > MAX_EPISODES_PER_CASSETTE regardless of cassette state. A cassette that grew past the cap historically but this run only *replayed* (dirty=False) is healthy — the persister never tries to save, so the cache state is stable and the next run will replay too. Only flag OVERFLOW when dirty=True (new episodes were recorded that the persister would refuse to save). Add a regression test covering the dirty=False + large-total case. 2. _module_uses_respx did substring matching on the module source, which false-positives on comments / docstrings / string literals. A comment like # Previously tried respx.mock but switched to vcrpy would keep a file pinned on the opt-out list, defeating the dead-import pruning goal of this PR. Replace the substring scan with an ast.NodeVisitor (_RespxUsageVisitor) that only counts: - @pytest.mark.respx / @respx.mock decorators - with respx.mock(): ... (sync + async) context managers - respx.mock(...) calls outside a with/decorator - function parameters / fixture names equal to respx_mock Add tests for the comment / docstring / string-literal cases plus each real-usage pattern. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(vcr): aggregate worker stats on the controller so the session summary actually renders under xdist `_session_stats` is a module-level dict mutated inside `_vcr_outcome_gate` — which runs in each xdist worker process. The controller's `pytest_terminal_summary` then reads its own empty `_session_stats` and bails on `if not counts: return`, so the OVERFLOW / LIVE_CALL sections the rest of this PR adds never make it into CI logs in the dist mode CI actually uses. Ship a structured `vcr_outcome` payload via `user_properties` (which xdist round-trips) and add `aggregate_report_outcome` on the controller to fold worker outcomes into `_session_stats`. The recording process tags `vcr_recorded_by` with `PYTEST_XDIST_WORKER` so the controller can tell "single-process — already counted locally" apart from "produced by a worker — needs aggregation here", and not double-count when there's no xdist. Covered by 9 new unit tests in test_vcr_classification.py including the end-to-end summary render path. * fix(guardrails): improve CrowdStrike AIDR input handling (#26658) * feat(lasso): add tool-calling support to LassoGuardrail (#27648) * feat(lasso): extend LassoGuardrail to support tool calling (RND-5748) * fix(lasso): PR review followups for tool-calling guardrail (RND-5748) * fix(lasso): handle object-style tool_calls in _update_tool_calls_from_masked (RND-5748) * fix(lasso): use model role for tool_use blocks (RND-5748) * test(lasso): add round-trip tests for message transformation (RND-5748) * fix(lasso): remove unused imports, handle Responses-API input masking, flatten multimodal content (RND-5748) * fix(lasso): inspect Responses-API input field (RND-5748) * fix(lasso): guard text-cursor remap against Lasso count mismatch (RND-5748) * fix(lasso): flatten list content in tool_result.content (RND-5748) * fix(lasso): remap multimodal list content during masking (RND-5748) Bug: _map_masked_messages_back counted list-content messages in original_text_count but the remap loop only handled isinstance(str). The positional text_cursor never advanced for list messages, causing all subsequent masked texts to be written onto the wrong messages. Fix: added elif isinstance(content, list) branch that replaces the list with the masked text string and advances the cursor — mirrors the existing string-content branch. Also handles the assistant + tool_calls combo for list-content messages. Test: test_map_masked_messages_back_list_content verifies a user message with [text + image_url] followed by an assistant message gets correct masked content on both (cursor stays aligned). * refactor(lasso): extract _get_field and _extract_tool_call_fields helpers (RND-5748) The dict-vs-object access pattern (x.get('y') if isinstance(x, dict) else getattr(x, 'y', None)) was duplicated 14 times across 5 methods. _get_field(obj, field) — single-point dict/Pydantic field access. _extract_tool_call_fields(call) — returns (call_id, name, parsed_input) with JSON argument parsing, replacing ~30 duplicate lines in both async_post_call_success_hook and _expand_messages_for_classification. Also simplified _update_tool_calls_from_masked, _prepare_payload tool mapping, and _apply_masking_to_model_response call_id extraction. Net ~60 lines removed. No behavior change — all 32 tests pass. * fix(lasso): add count guard to _apply_masking_to_model_response (RND-5748) _apply_masking_to_model_response used a bare text_cursor without verifying 1:1 correspondence between text-bearing choices and masked text entries. If Lasso returned a different number of text messages than choices with content, masked text would be applied to the wrong choice or silently skip choices. Added the same count-mismatch guard pattern already used in _map_masked_messages_back: count original text-bearing choices, compare to masked_text length, skip text remap on mismatch with a warning log. Tool_call masking via id-based lookup is unaffected. Tests: - test_apply_masking_to_model_response_multiple_choices: verifies correct per-choice masked text with 2 choices - test_apply_masking_to_model_response_count_mismatch: verifies content is left unchanged when counts disagree * fix(lasso): close two guardrail-bypass paths flagged in review (RND-5748) * tool-call args: when function.arguments is malformed JSON or parses to a non-object, preserve the raw string as {"arguments": <raw>} so Lasso still inspects it instead of receiving input=None. Covers both pre-call and post-call extraction (shared helper). Also resolves the CodeQL empty-except warning since the except body now assigns parsed=None. * Responses-API input: when a request carries both "messages" and "input", inspect both. Previously a benign messages array let the guardrail skip data["input"] entirely. The masking write-back is split via a count boundary so masked messages flow back to data["messages"] and masked input flows back to data["input"] without cross-contamination. Tests: malformed/non-object args round-trip, dual-field classification, dual-field masking write-back split. * chore(lasso): black formatting + comment on expand skip branch (RND-5748) * black: wrap two long expressions in lasso.py and reformat dict literals in test_lasso.py to satisfy CI lint. * add a short comment in _expand_messages_for_classification explaining why empty string and None content are intentionally skipped (None is the OpenAI shape for a pure tool-call turn). * fix(lasso): satisfy mypy in _handle_masking, _update_tool_calls_from_masked, _apply_masking_to_model_response (RND-5748) * Narrow `response.get("messages")` into a local before slicing so mypy doesn't see `Optional[List[Dict[str, str]]]` as non-indexable. * Rename the two write-side `func` bindings in `_update_tool_calls_from_masked` to `func_dict` / `func_obj` so mypy doesn't unify the dict and Any|None branches. * Rename the inner loop variable in `_apply_masking_to_model_response` from `msg` to `masked_msg` to avoid clashing with the `msg = choice.message` rebinding below. No behavior change; resolves the 7 mypy errors from the CI lint job. * perf: eliminate per-request callback scanning on proxy hot path (#27858) - Introduce `_CallbackCapabilities` dataclass and `ProxyLogging._callback_capabilities()` static method that inspects `litellm.callbacks` once and caches capability flags keyed on (list length, member ids); invalidates automatically when the callback list mutates without per-request iteration overhead - Replace O(n) `litellm.callbacks` walks in `async_pre_call_hook`, `during_call_hook`, `async_post_call_streaming_iterator_hook`, `async_post_call_streaming_hook`, and `post_call_response_headers_hook` with fast-path exits when no relevant callbacks are registered - Add `needs_iterator_wrap()` and `needs_per_chunk_streaming_hook()` instance methods to decouple iterator-level wrapping from per-chunk hook execution; avoids `get_response_string` materialization per chunk when no guardrail or chunk-hook callback is active - Introduce `_fast_serialize_simple_model_response_stream()` using `orjson` for common single-choice text streaming chunks, bypassing the full Pydantic serializer; falls back to `model_dump_json` for tool calls, logprobs, usage, and provider-specific fields - Add early-return in `_restamp_streaming_chunk_model` when downstream model already matches the requested model, avoiding unnecessary string comparisons on every chunk - Fix stale zero-cost cache bug in `_is_model_cost_zero`: move the per-router `_zero_cost_cache` dict onto the `Router` instance and clear it in `_invalidate_model_group_info_cache` so in-place pricing updates via `upsert_deployment` immediately resume budget enforcement - Add `scripts/benchmark_chat_completions_perf.py`: standalone async benchmarking tool with a mock OpenAI provider, LiteLLM proxy process management, non-streaming RPS, streaming TTFT, and full-stream latency measurements with repeat/median run support - Add comprehensive unit tests covering capability detection, cache invalidation, fast-path correctness, zero-cost cache regression, and the no-callback streaming fast path Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu> * ci(mutmut): enable mutate_only_covered_lines to fit in CI budget (#27910) The mutation-test workflow timed out at the 350-minute job cap when running whole-folder mutation against litellm/proxy/management_endpoints/ (~30 files, ~1.5 MB of source). Every mutant was running the full test suite, and mutants were generated for lines no test covers — which would survive regardless, just wasting compute. mutmut 3.x's mutate_only_covered_lines setting runs the suite once up front to compute coverage, then skips mutating uncovered lines. This cuts the mutant count dramatically and is the right semantic for the score (no test → no kill possible → uncountable). Per-mutant test filtering by function name is already automatic in mutmut 3.x; no external coverage step is needed. * fix(rate-limit): stop v3 limiter from leaking internal stash to provider body (#27913) * fix(rate-limit): stop v3 limiter from leaking internal stash to provider body PR #27001 (atomic TPM rate limit) introduced a reservation flow that writes four LiteLLM-internal keys onto the request data dict: _litellm_rate_limit_descriptors _litellm_tpm_reserved_tokens _litellm_tpm_reserved_model _litellm_tpm_reserved_scopes _litellm_tpm_reservation_released These keys are forwarded as request body params to the upstream provider, which rejects them as unknown fields: OpenAI -> 400 'Unknown parameter: _litellm_rate_limit_descriptors' (mapped by litellm to RateLimitError / 429, hiding the bug behind a misleading 'throttling_error' code) Anthropic -> 400 '_litellm_rate_limit_descriptors: Extra inputs are not permitted' Net effect: every chat completion against any real provider fails the moment a virtual key has any tpm_limit / rpm_limit set — i.e. v3-enforced key-level TPM/RPM limits are broken end-to-end. The v3 RPM/TPM check itself still runs (raises 429 on over-limit), but the success path poisons the upstream body. Reproduced on litellm_internal_staging HEAD (410ce761dc) against gpt-4o-mini and claude-haiku-4-5 with a 1-RPM/1-TPM key — first request fails with the provider's unknown-field error. Fix: the stash is metadata only. - Add RATE_LIMIT_DESCRIPTORS_KEY constant and a _LITELLM_STASH_KEYS registry so we have a single source of truth for stash keys. - New helper _stash_value_in_metadata_channels writes to data['metadata'] / data['litellm_metadata'] without touching the top level. - _stash_reservation_in_data and the descriptor stash now route through that helper. _mark_reservation_released stops writing top-level. - _lookup_stashed_value also checks kwargs['metadata'] / kwargs['litellm_metadata'] (raw request_data shape) in addition to kwargs['litellm_params']['metadata'] (completion kwargs shape). - async_post_call_failure_hook now reads descriptors via the unified metadata lookup instead of request_data.get(top-level). - Defense in depth: async_pre_call_hook strips any stash key that somehow surfaced at the top level (stale cache, future refactor, test fixture) before returning. Tests: - New regression test asserts no _litellm_* stash key is present at the top level of data after async_pre_call_hook, and that the metadata channel still carries the reservation + descriptors so success / failure reconciliation works. - Existing test_tpm_concurrent.py tests that asserted top-level presence are updated to read from data['metadata'] — the location is an implementation detail; the spec is that post-call callbacks can resolve the stash. Verified end-to-end against OpenAI gpt-4o-mini and Anthropic claude-haiku-4-5 via /v1/chat/completions on a low-rpm key: - With limits not exceeded: HTTP 200, valid completion response, no leaked fields in body. - With RPM exceeded: HTTP 429 from v3 enforcement ('Rate limit exceeded ... Limit type: requests'). - With TPM exceeded: HTTP 429 from v3 enforcement ('Rate limit exceeded ... Limit type: tokens'). Full v3 hook test suite passes (171 tests).

Drop comments that re-explain what well-named identifiers already convey. * fix(rate-limit): reject caller-supplied stash values to prevent TPM-refund abuse Strip _LITELLM_STASH_KEYS from data top-level and both metadata channels at the start of async_pre_call_hook. Without this, an authenticated caller can inject _litellm_rate_limit_descriptors plus _litellm_tpm_reserved_tokens in body metadata, trigger a proxy-side rejection, and cause async_post_call_failure_hook to refund TPM counters against attacker-named scopes (e.g. another tenant's api_key). --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix: allow for allowlisted redirect URIs (#27761) * fix: allow for allowlisted redirect URIs * github comment addressing * Update litellm/proxy/_experimental/mcp_server/oauth_utils.py Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> * harden oauth wildcard further * test: cover wildcard entry with dot-leading suffix rejection --------- Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> * Emit native web_search_tool_result blocks for Anthropic clients (Claude Desktop / Cowork citations) (#27886) * feat(custom_logger): add async_post_agentic_loop_response_hook Lets a CustomLogger shape the response returned by the agentic-loop follow-up call without bypassing the loop's safety / observability machinery (depth tracking, fingerprinting, etc.). Default returns the response unchanged. Used by websearch_interception to inject Anthropic-native web_search_tool_result blocks when the originating client requested a native web_search_* tool. * feat(llm_http_handler): call post-agentic-loop hook on the originating callback In _execute_anthropic_agentic_plan, after anthropic_messages.acreate returns, call the originating callback's async_post_agentic_loop_response_hook so it can mutate the final response (e.g. inject native tool_result blocks). Pass the callback through from _call_agentic_completion_hooks. Exceptions in the post-hook are caught and logged so a buggy callback can't kill the request. * feat(websearch_interception): add is_anthropic_native_web_search_tool Identifies tools the Anthropic-native clients (Claude Desktop, the Anthropic SDK, the Anthropic Console) use to request native search: type starts with "web_search_" (e.g. web_search_20250305). Rejects the LiteLLM standard tool, the OpenAI-function variant, the bare "WebSearch" legacy name, and the bare "web_search" Claude Code shape. This lets us decide per-request whether the client expects web_search_tool_result content blocks in the response, without renaming any existing constants or touching native-provider skip logic. * feat(websearch_interception): add build_web_search_tool_result_block Produces the Anthropic-native web_search_tool_result content block from a structured SearchResponse. Anthropic-native clients use this block to populate citations / source links — the existing text-blob flatten path only feeds readable evidence to the model and discards the structure, so this builder gives us the missing piece. Shape matches https://docs.anthropic.com/en/api/web-search-tool — web_search_result items carry url, title, page_age, encrypted_content (empty string when the search provider doesn't supply one). * feat(websearch_interception): emit native web_search_tool_result blocks When the originating client request carried a native Anthropic web_search_* tool, the final response now also carries web_search_tool_result content blocks alongside the model's text answer — so Claude Desktop / Anthropic SDK clients can populate the citations panel and replay conversation history with structured search evidence. Wiring: - Pre-request hooks (both deployment + Anthropic path) set a flag on kwargs when they see a native web_search_* tool, so the signal survives the conversion-to-litellm_web_search step regardless of which hook fires first. - _execute_search now returns (text, SearchResponse) so the structured results aren't lost when the text is flattened for the follow-up model call. - _build_anthropic_request_patch returns the parallel list of SearchResponse objects. - async_build_agentic_loop_plan pre-builds the web_search_tool_result blocks (one per tool_use_id) and stashes them on plan.metadata when the flag is set. - async_post_agentic_loop_response_hook reads the metadata and prepends the blocks to response.content. - _execute_agentic_loop mirrors the injection for the legacy path so both paths behave identically. Clients that send the LiteLLM standard tool keep the existing text-only behavior — no regression. * test(websearch_interception): cover native web_search_tool_result emission 18 tests across: - detector branches (native vs litellm-standard, OpenAI-function shape, Claude Desktop builtin WebSearch, bare web_search, missing type) - block-builder shape (results, none, empty) - pre-request hook flag-setting (native sets, standard does not) - async_build_agentic_loop_plan attaches blocks to plan.metadata when the flag is present, leaves metadata untouched when absent - post-hook injection into dict and object responses - legacy _execute_agentic_loop mirrors the injection so both paths return the same shape * test(websearch_short_circuit): keep _execute_search mocks in sync with new tuple return * test(websearch_thinking_constraint): keep _execute_search mocks in sync with new tuple return * feat(websearch_interception): emit native blocks from try_short_circuit_search The agentic-loop post-hook only fires when the model returns a tool_use block. Cowork / Claude Desktop on Bedrock actually make TWO requests per user turn: the main /v1/messages with their builtin tool, and a separate standalone /v1/messages whose only tool is web_search_20250305. That second request hits try_short_circuit_search — no agentic loop, no post-hook — and was returning text-only, leaving the citations panel empty. When the short-circuit input carries a native web_search_* tool, build a synthetic server_tool_use + web_search_tool_result pair (using the structured SearchResponse already returned by _execute_search) so the client gets the native shape it expects. The legacy text block is preserved so non-native short-circuit callers (Claude Code, github_copilot, etc.) see the same payload as before. Failure path still emits the native block pair (with empty results) plus the text-error block, so the client gets a well-formed response rather than a malformed half-shape. * test(websearch_native_blocks): cover short-circuit native-block emission Three new cases on top of the existing 18: - native web_search_20250305 short-circuit → [server_tool_use, web_search_tool_result, text], ids paired, urls/titles carried. - litellm_web_search short-circuit → text-only (no regression). - native short-circuit on search failure → still emits the native block pair (empty results) plus the text-error block, so the client never sees a malformed half-shape. * test(websearch_short_circuit): index assertions by block type, not by position Native short-circuit responses now have [server_tool_use, web_search_tool_result, text] when the input carries web_search_20250305 — find the text block by type rather than relying on content[0]. * fix(websearch_interception): gate legacy WebSearch name on schema absence Clients like Cowork / Claude Desktop ship a client-side tool named "WebSearch" with a full input_schema — they handle it themselves and expect to make a separate native web_search_20250305 sub-request for the actual search. Today is_web_search_tool matches the bare name regardless of other fields, which hijacks the client's tool server-side. The agentic loop fires on the main request, the model never gets to emit the client-side tool_use, and the separate native sub-request (where citation data flows) is never made. Net: citations panel empty. Real Anthropic client tools always carry input_schema (the API rejects them otherwise), so a bare {name: "WebSearch"} with no schema is the only thing that could be a legacy interception marker. Gate the match on schema absence: legacy callers (if any) keep working, real client-side WebSearch tools pass through untouched. * fix(websearch_interception): drop "WebSearch" from response-detection lists Post-conversion the model always sees ``litellm_web_search``, so the "WebSearch" entry in the response-side tool_use detection lists was dead at best. If a model ever did return ``tool_use(name="WebSearch")`` it would now (incorrectly) hijack the client's own ``WebSearch`` tool again — same Cowork problem we just fixed on the input side. Drop it. * test(websearch_native_blocks): cover the WebSearch legacy-name schema gate Three new cases: - {name: "WebSearch"} (bare interception marker) → still matched - {name: "WebSearch", input_schema: {...}} (Cowork client tool) → passes through untouched - {name: "WebSearch", description: "..."} (no schema) → still matched on the assumption it's a legacy marker rather than a malformed real client tool. --------- Co-authored-by: Ishaan Jaffer <ishaanjaffer0324@gmail.com> * ci(codecov): restore litellm/ prefix on uploaded coverage paths pytest-cov runs with --cov=litellm, which makes coverage.xml store paths relative to the package root (e.g. `proxy/proxy_server.py` instead of `litellm/proxy/proxy_server.py`). Codecov auto-resolves these only when the basename is unique in the repo. Files like proxy_server.py, router.py, utils.py, main.py, and constants.py — which have duplicates under enterprise/ or other subpackages — get silently dropped during ingest. The `fixes: ["::litellm/"]` rule prepends `litellm/` to every uploaded path so they resolve unambiguously. Confirmed against multiple recent coverage.xml artifacts that no uploader currently emits paths already prefixed with `litellm/`, so the rule is safe to apply universally. This restores Codecov visibility for the highest-fix-rate hotspots: proxy_server.py, router.py, proxy/utils.py, litellm_logging.py, constants.py, key_management_endpoints.py, utils.py, main.py, user_api_key_auth.py, team_endpoints.py, and litellm_pre_call_utils.py. * chore(ci): remove unused GitHub Actions workflows and orphan files Audit of .github/workflows/ via gh run history shows the following have either never run or have been dormant for 10+ weeks. CI coverage that still matters is preserved on CircleCI (e.g. llm_translation_testing). Removed workflows: - test-litellm.yml — workflow_dispatch only, last run 2026-02-12 (cancelled); CCI local_testing_part1/2 covers the same tests - llm-translation-testing.yml — last run 2025-07-10; replaced by CCI llm_translation_testing job (run_llm_translation_tests.py kept for the make test-llm-translation target) - run_observatory_tests.yml — last run 2026-03-03 (cancelled) - scan_duplicate_issues.yml — last run 2026-03-02 (failure) - publish_to_pypi.yml — never run - read_pyproject_version.yml — fires on every push to main but its echoed version output is not consumed by any downstream step Removed orphan files (no callers in workflows, CCI, or Makefile): - .github/workflows/README.md — documented only publish_to_pypi.yml - .github/workflows/update_release.py + results_stats.csv - .github/actions/helm-oci-chart-releaser/ * Revert "ci(codecov): restore litellm/ prefix on uploaded coverage paths" This reverts commit e25a988a3f. The `fixes: ["::litellm/"]` rule turned out to be applied *after* Codecov's auto-resolution, not before. Files with unique basenames (which were auto-resolving correctly to `litellm/<path>`) got an extra `litellm/` prepended, producing `litellm/litellm/<path>` storage. Files with ambiguous basenames (the actual target of the fix) continued to be dropped because the auto-resolution still failed for them. Net result on the verification run: 1375 files now stored under unresolvable `litellm/litellm/...` paths, and the 11 originally-missing hotspots are still missing. Reverting before piling on further changes. * test(ui): preserve global Button/Tooltip mocks in per-file @tremor/react vi.mock Per-file `vi.mock("@tremor/react", ...)` factories fully replace the setup-level mock from `tests/setupTests.ts`, so the global Button/Tooltip overrides are lost in any file that re-mocks `@tremor/react`. Without them, the real Tremor `<Button>` leaks through and its internal `useTooltip(300)` schedules a native 300ms `setTimeout` on pointer events. When the test environment is torn down before the timer fires, the trailing `setState` calls `getCurrentEventPriority`, which reads `window.event` against a destroyed jsdom -> "window is not defined" flake observed on CI. Patches the 7 leaky test files to re-supply `Button` (bare `<button>`) and `Tooltip` (Fragment) overrides matching `setupTests.ts`. Also drops a dead `afterEach` workaround in `user_edit_view.test.tsx` (the fake-timer dance it ran could not drain a real timer scheduled before the swap) and corrects a misleading comment in `MakeMCPPublicForm.test.tsx`. * ci: use --cov=./litellm so coverage paths resolve unambiguously in Codecov pytest-cov treats --cov=<module-name> as a Python package and emits XML paths relative to the package root, stripping the litellm/ prefix (`proxy/proxy_server.py` instead of `litellm/proxy/proxy_server.py`). Codecov's auto-prefix heuristic then drops every file whose basename is ambiguous in the repo — `proxy_server.py` (3 copies under enterprise/), `router.py` (2 copies), `utils.py` (20+), `main.py` (20+), `constants.py` (2). The 11 highest-fix-rate hotspots have never appeared in Codecov. Switching to --cov=./litellm treats the argument as a path, which makes coverage.xml emit repo-relative paths (`litellm/proxy/proxy_server.py`). Each path is unambiguous, so Codecov resolves all files correctly. Verified locally: rerunning a single proxy_unit_tests test with --cov=./litellm produced `filename="litellm/proxy/proxy_server.py"`, `filename="litellm/router.py"`, and `filename="litellm/types/router.py"` as distinct entries — exactly the disambiguation Codecov needs. Touches every workflow that uploads coverage: the two reusable GHA workflows (_test-unit-base.yml, _test-unit-services-base.yml), test-mcp.yml, and all 14 invocations in .circleci/config.yml. * fix(mcp): allow delegate PKCE bypass for internal MCP servers Remove available_on_public_internet gating from delegate-auth-to-upstream paths so oauth2 + delegate_auth_to_upstream interactive servers behave the same when marked internal.

Two bugs fixed: 1. batch_utils.py: the Vertex-specific cost/usage reader (calculate_vertex_ai_batch_cost_and_usage) was always invoked and reads raw usageMetadata fields that no longer exist in the OpenAI-shaped output. Now the reader is only used when disable_vertex_batch_output_transformation=True; otherwise the generic path handles the already-transformed OpenAI-shaped content. 2. cost_calculator.py: batch_cost_calculator skipped the global litellm.get_model_info() lookup when a model_info dict was passed in, even when that dict had no pricing fields (e.g. deployment metadata with only id/db_model). It now falls back to the global pricing table when the provided model_info has no pricing data.

Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): ensure weighted failover metadata persists in kwargs The previous `kwargs.setdefault(metadata_variable_name, {}) or {}` returned a brand-new dict whenever the existing metadata was falsy (empty dict or None), so writes to `_failover_excluded_ids` never made it back into `kwargs`. Multi-hop weighted failover then re-selected previously failed deployments and exhausted `max_fallbacks` prematurely. Explicitly assign a fresh dict into kwargs when metadata is missing so mutations are visible to subsequent failover hops. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(router): regression for weighted failover metadata persistence Asserts kwargs["metadata"]["_failover_excluded_ids"] is populated after _maybe_run_weighted_failover, proving the metadata dict written by the helper is the same object that lives in kwargs (no disconnected copy). Pairs with the prior fix that replaced `setdefault(..., {}) or {}` with an explicit get/assign so writes survive across hops. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): harden weighted failover error/state handling - Catch RouterRateLimitError (ValueError) alongside openai.APIError in _maybe_run_weighted_failover so an exhausted intra-group retry falls through to the regular cross-group fallback path instead of bubbling out and bypassing configured fallbacks. - Stop mutating the shared input_kwargs dict; build a local copy with the weighted-failover keys so the entry (with _excluded_deployment_ids) cannot leak into later fallback paths reading the same dict. - _get_excluded_filtered_deployments now returns an empty list when the exclusion filter removes every healthy deployment, instead of falling back to the original list. The original-list behavior risked re-picking the just-failed deployment; callers already handle the empty case by raising their no-deployments error, which weighted failover now catches and converts into a normal cross-group fallback. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(router): fall through to rpm/tpm when total weight is zero When the weight metric's total is zero (e.g. after weighted-failover exclusion leaves only zero-weight backups), continue to the next metric (rpm/tpm) instead of returning a uniform random pick immediately. This lets rpm/tpm still drive routing when present, and only falls back to the uniform random pick at the end if no metric provides a positive total weight. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(router): skip weighted failover when remaining deployments are all in cooldown _maybe_run_weighted_failover was computing 'remaining' from all_deployments (every deployment in the model group, including those in cooldown). This meant that when all non-excluded deployments were in cooldown the method still invoked run_async_fallback unnecessarily, which propagated into async_get_healthy_deployments, found no eligible deployments, and raised RouterRateLimitError — only safely caught thanks to the earlier exception-broadening fix. The fix: before computing 'remaining', fetch the current cooldown set via _async_get_cooldown_deployments and subtract it from all_ids. This allows _maybe_run_weighted_failover to return None immediately (skipping the run_async_fallback call entirely) when every non-failed deployment is in cooldown, letting the caller fall through to the correct cross-group fallback path without the wasteful extra round-trip. Tests added: - unit: _maybe_run_weighted_failover returns None without calling run_async_fallback when all remaining deployments are in cooldown - unit: _maybe_run_weighted_failover still calls run_async_fallback when at least one healthy (non-cooldown) deployment is available - integration: end-to-end fallthrough to cross-group fallback when remaining deployments are in cooldown Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: Yassin Kortam <yassin@berri.ai> Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix(bedrock-mantle): use /anthropic/v1/messages path for Mantle endpo… (#27976) * fix(bedrock-mantle): use /anthropic/v1/messages path for Mantle endpoint (#27943) * docs: add one-line docstring to _disable_debugging (#27894) Squash-merged by litellm-agent from oss-agent-shin's PR. * Add jp.

Re-submitting a value the Admin UI read back from /get/config/callbacks as ciphertext no longer stacks a second encryption layer, which previously decrypted to garbage and silently broke the callback. The chokepoint decrypts with the pure _decrypt_db_variables (no os.environ mutation on the write path) and encrypts exactly once; update_config merges only the sent keys so untouched env vars keep their stored ciphertext byte-for-byte. * test(proxy): add endpoint-level regression for /config/update double-encryption Adds test_update_config_env_var_round_trip_not_double_encrypted, which drives the real /config/update handler: first write plaintext, then re-POST the stored ciphertext (the Admin UI round-trip) and assert the value is not stacked with a second encryption layer and untouched keys stay byte-identical. Verified to fail against the pre-fix handler and pass after. Also tightens the unit test to exactly three ciphertext re-feeds. * chore(ci): modernize model references in tests and configs (#27856) * test: modernize models used in CircleCI e2e test suites Replaces obsolete models (gpt-4o, gpt-4o-mini, gpt-3.5-turbo, claude-3-5-sonnet-20240620, claude-sonnet-4-20250514) with current equivalents across the e2e_openai_endpoints and proxy_e2e_anthropic_messages_tests CircleCI jobs. - gpt-4o -> gpt-5.5 (responses API e2e tests) - gpt-4o-mini -> gpt-5-mini (websocket responses, oai_misc_config) - gpt-4o-mini-2024-07-18 -> gpt-4.1-mini-2025-04-14 (fine-tuning, still actively fine-tunable) - gpt-4 / gpt-3.5-turbo target_model_names example -> gpt-5.5 / gpt-5-mini - bedrock claude-3-5-sonnet-20240620 batch entry -> haiku-4-5-20251001 (also aligning oai_misc_config model_name with what test_bedrock_batches_api.py actually requests) - bedrock claude-sonnet-4-20250514 (deprecated, retires 2026-06-15) -> claude-sonnet-4-5-20250929 * test: point bedrock-claude-sonnet-4 alias at Sonnet 4.6, not 4.5 Greptile/Cursor flagged that after the previous commit, the bedrock-claude-sonnet-4 alias collided with bedrock-claude-sonnet-4.5 (both pointed to claude-sonnet-4-5-20250929). Rename to bedrock-claude-sonnet-4.6 and point it at the Sonnet 4.6 Bedrock ID (us.anthropic.claude-sonnet-4-6, already in the litellm model registry) so the alias name matches the underlying model version. * test: modernize models across remaining CI-mounted configs & tests Expands the modernization sweep to all CircleCI-mounted proxy configs and to test directories where the model literal is a fixture/route key (not the test's subject). Config changes: - proxy_server_config.yaml: bump gpt-3.5-turbo / gpt-3.5-turbo-1106 / gpt-4o / gemini-1.5-flash / dall-e-3 underlying models; rename gpt-3.5-turbo-end-user-test alias to gpt-5-mini-end-user-test; bump text-embedding-ada-002 underlying to text-embedding-3-small. User- facing aliases (gpt-3.5-turbo, gpt-4, text-embedding-ada-002, etc.) preserved for backward compatibility with tests. - simple_config.yaml, otel_test_config.yaml, spend_tracking_config.yaml: bump gpt-3.5-turbo underlying to gpt-5-mini. - pass_through_config.yaml: claude-3-5-sonnet / claude-3-7-sonnet / claude-3-haiku entries replaced with claude-sonnet-4-5 / claude- haiku-4-5 / claude-opus-4-7. - oai_misc_config.yaml: align alias name with the gpt-5-mini rename. Test changes (proactive: claude-sonnet-4-20250514 / claude-opus-4- 20250514 retire 2026-06-15): - tests/llm_translation/test_anthropic_completion.py: bump 3 references + paired Vertex AI ID to claude-sonnet-4-5. - tests/llm_translation/test_optional_params.py: bump 2 references. - tests/pass_through_unit_tests/test_anthropic_messages_passthrough.py and test_bedrock_anthropic_messages_test.py: bump router fixtures using the deprecated model IDs. - tests/pass_through_unit_tests/base_anthropic_messages_tool_search_test.py: modernize docstring examples. - tests/test_end_users.py: update references to renamed alias. * test: modernize placeholder model literals in router_unit_tests Mass replace_all on fixture/placeholder model literals across the router_unit_tests/ suite (model name is a routing key / label, not the test subject). Sub-agent sweep so far — additional commits will follow for logging_callback_tests/, enterprise/, top-level tests/test_*.py, and other CI-mounted dirs. Mappings applied: - gpt-3.5-turbo -> gpt-5-mini - gpt-4 (bare) -> gpt-5.5 - gpt-4o (bare) -> gpt-5 - text-embedding-ada-002 -> text-embedding-3-small - claude-3-sonnet-20240229 / claude-3-opus-20240229 / claude-3-haiku-20240307 / claude-3-5-sonnet-20240620 -> claude-sonnet-4-5-20250929 / claude-opus-4-7 / claude-haiku-4-5-20251001 as appropriate Explicitly preserved: - gpt-4o-mini-* variants (transcribe, tts, etc.) where they're current - gpt-4-turbo / gpt-4-vision-preview / gpt-4-0613 (subject literals) - JSONL batch body literals - Mock LLM response model fields (must match upstream) - Fake/mock identifiers * test: modernize placeholder model literals across remaining CI suites Sub-agent sweep across logging_callback_tests/, guardrails_tests/, enterprise/, pass_through_unit_tests/, otel_tests/, llm_responses_api_testing/, batches_tests/, spend_tracking_tests/, litellm_utils_tests/, unified_google_tests/, and a few top-level tests/test_*.py files where the model literal is a fixture or placeholder (router model_list, mock standard logging payload, mock callback data) rather than the test's subject. Mappings applied (see scope notes below): - gpt-3.5-turbo -> gpt-5-mini - gpt-4 (bare) -> gpt-5.5 - gpt-4o (bare) -> gpt-5.5 (corrected from initial gpt-5 — bare gpt-5 is not a valid OpenAI alias; only gpt-5.5 / gpt-5.4 / gpt-5.2-codex / gpt-5-mini exist) - gpt-4o-mini (bare) -> gpt-5-mini - text-embedding-ada-002 -> text-embedding-3-small - claude-3-sonnet-20240229 -> claude-sonnet-4-5-20250929 - claude-3-opus-20240229 -> claude-opus-4-7 - claude-3-haiku-20240307 -> claude-haiku-4-5-20251001 - claude-3-5-sonnet-20240620/20241022 -> claude-sonnet-4-5-20250929 - claude-3-7-sonnet-20250219 -> claude-sonnet-4-6 - gemini-1.5-flash -> gemini-2.5-flash - gemini-1.5-pro -> gemini-2.5-pro Explicitly preserved (not modernized): - llm_translation/ tests where model is the SUBJECT (provider-specific translation/transformation logic). Only the deprecated 20250514 references were already bumped in a prior commit. - Cost-calc / tokenizer subject tests in test_utils.py (skip-ranges documented by the sub-agent). - Bedrock model IDs in test_health_check.py path-stripping tests. - JSONL batch request bodies and mock LLM response bodies (must match upstream literal). - Langfuse expected-request-body JSON fixtures (cost values are exact- match-asserted; changing the model would shift response_cost). - gpt-3.5-turbo-instruct (text-completion endpoint; no modern OpenAI equivalent). - Top-level tests calling the proxy through user-facing aliases (gpt-3.5-turbo, gpt-4, text-embedding-ada-002, dall-e-3) — aliases in proxy_server_config.yaml stay; only the underlying model was bumped. - tests/test_gpt5_azure_temperature_support.py (the test's whole point is model-name handling). - Fake / mock / openai/fake identifiers. Notable side fixes: - test_spend_accuracy_tests.py: UPSTREAM_MODEL now matches what spend_tracking_config.yaml's proxy actually routes to (gpt-5-mini), resolving a latent inconsistency. - proxy_server_config.yaml: bare `gpt-5` alias renamed to `gpt-5.5` (bare gpt-5 is not a valid OpenAI alias). - test_batches_logging_unit_tests.py: explicit_models list entries kept distinct (gpt-5-mini + gpt-5.5) after bulk rename. * test: fix CI failures from model modernization sweep CI surfaced 4 categories of regression from the bulk modernization: 1. Azure deployment names are customer-specific. Reverted: - tests/litellm_utils_tests/test_health_check.py: azure/text- embedding-3-small -> azure/text-embedding-ada-002 (the CI Azure account does not have a text-embedding-3-small deployment). - tests/logging_callback_tests/test_custom_callback_router.py: same revert for two router fixtures driving aembedding. 2. gpt-5 family does not accept temperature != 1. Tests that pass a custom temperature swapped from gpt-5-mini to gpt-4.1-mini (modern non-reasoning OpenAI mini that still accepts temperature/logprobs): - tests/logging_callback_tests/test_datadog.py - tests/logging_callback_tests/test_langsmith_unit_test.py - tests/logging_callback_tests/test_otel_logging.py 3. proxy_server_config.yaml's gpt-3.5-turbo-large alias was routing to gpt-5.5 (a reasoning model that rejects logprobs). The proxy test tests/test_openai_endpoints.py::test_chat_completion_streaming exercises logprobs/top_logprobs through that alias. Bumped the underlying model to gpt-4.1 (non-reasoning, still modern). 4. tests/logging_callback_tests/test_gcs_pub_sub.py asserts against a pinned JSON fixture (gcs_pub_sub_body/spend_logs_payload.json) with hardcoded model="gpt-4o" and a model-specific spend value. Reverted the litellm.acompletion calls in the test to model="gpt-4o" so the fixture's exact-match assertions still hold. 5. tests/pass_through_unit_tests/test_anthropic_messages_passthrough.py: anthropic.messages.create routing to openai/gpt-5-mini returned an empty content[0] with max_tokens=100 (reasoning-token consumption). Swapped to openai/gpt-4.1-mini. * test: fix Assistants API model + 2 cursor[bot] review nits 1. pass_through_unit_tests/test_custom_logger_passthrough.py: gpt-5.5 isn't accepted by the /v1/assistants endpoint ("unsupported_model"). Switch to gpt-4.1-mini (modern, Assistants- API-supported, non-reasoning). 2. example_config_yaml/pass_through_config.yaml: the previous sweep bumped the claude-3-7-sonnet alias to claude-opus-4-7, which is a tier change (Sonnet -> Opus). Map to claude-sonnet-4-6 to keep the Sonnet tier intact. (Cursor bugbot review.) 3. example_config_yaml/simple_config.yaml: model_name was left as gpt-3.5-turbo while the underlying was bumped to gpt-5-mini, which muddles the "simple" example. Make both sides gpt-5-mini so the most basic example is a straight 1:1 mapping again. (Cursor bugbot review.) * fix: revert gpt-4/gpt-3.5-turbo alias underlying to non-reasoning models tests/test_openai_endpoints.py::test_completion calls the proxy alias "gpt-4" with temperature=0, and other tests call gpt-3.5-turbo with custom temperature / logprobs / the legacy /v1/completions endpoint. The earlier modernization mapped both aliases to gpt-5.5 / gpt-5-mini, which are reasoning models that reject temperature != 1 and don't expose /v1/completions. Map the aliases to gpt-4.1 / gpt-4.1-mini (modern non-reasoning OpenAI models) instead — keeps user-facing aliases preserved while picking a current underlying that still supports the parameters/endpoints the tests exercise. * test(proxy): isolate run_server CLI tests from prisma DB-setup path test_keepalive_timeout_flag and test_timeout_worker_healthcheck_flag were the only run_server tests in test_proxy_cli.py that neither stripped DATABASE_URL/DIRECT_URL nor mocked the prisma DB path. When a DATABASE_URL is present (CI/env leak), run_server --local enters the DB block and blocks in the un-timeout'd subprocess.run(["prisma"]) at proxy_cli.py:987 plus the ProxyExtrasDBManager migrate-deploy retry loops, ~370s per test on the CI runner. --dist=loadscope pins both to one xdist worker, so the proxy-infra job appears stuck at 99% and hits the 20-min timeout. Apply the same isolation every other run_server test in this file already uses: mock PrismaManager.setup_database + should_update_prisma_schema and strip DATABASE_URL/DIRECT_URL. Full module drops from 31.7s to 2.9s locally; both tests fall off the slow list. * feat: add OTEL GenAI latest-experimental semantic convention support (#27418) - Introduce `OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental` opt-in that switches OTEL traces to conform with the OpenTelemetry GenAI semantic conventions specification - Extract all semconv behavior into a new `OTELGenAISemconvMixin` class in `gen_ai_semconv.py`, mixed into `OpenTelemetry` to keep concerns separated - In semconv mode, span name follows `{operation} {model}` pattern (e.g. `chat gpt-4`) and span kind is set to `CLIENT` instead of legacy `litellm_request` - Replace `gen_ai.system` with `gen_ai.provider.name` and drop `llm.is_streaming` in semconv mode; add `gen_ai.request.{frequency_penalty,presence_penalty,top_k,seed,stop_sequences,stream,choice.count}` and `gen_ai.usage.cache_{creation,read}.input_tokens` attributes - Replace per-message `gen_ai.content.prompt` / per-choice `gen_ai.content.completion` log events with a single consolidated `gen_ai.client.inference.operation.details` event; omit `gen_ai.input/output.messages` when content capture is disabled - Suppress the non-standard `raw_gen_ai_request` child span entirely in semconv mode - Support both programmatic (`OpenTelemetryConfig.semconv_stability_opt_in` field) and environment variable activation; the two sources are unioned so either or both can enable the opt-in - Extract OTEL SDK `LogRecord` / `SeverityNumber` version-compatibility shim into a reusable `_otel_log_types()` static method to deduplicate the `< 1.39.0` / `>= 1.39.0` import branching - Add 30+ unit tests covering opt-in gating, span naming, attribute emission/omission rules, stop sequence normalization, cache token attributes, and the consolidated event lifecycle Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu> * chore: retrigger CI * test(ci): add reasoning_effort grid v4 e2e regression suite Encode the 231-cell QA sweep (21 provider x model combos x 11 effort values) from #27039 / #27074 as an automated CircleCI-gated regression suite. Each cell hits the real provider endpoint, captures the outgoing wire body via a pre-call CustomLogger, and asserts: - thinking.type, output_config.effort, thinking.budget_tokens, max_tokens in the captured request body (regression signal for silent drops/strips in any provider transformation) - HTTP status (200 vs BadRequestError -> 400) returned by litellm (regression signal for clean-error vs leaked-500 mappings) The matrix is encoded as a small rule set keyed by (model_mode, effort) plus per-model xhigh/max capability overrides, then expanded across the five chat-completion routes (Anthropic direct, Azure AI Foundry, Vertex AI, Bedrock Converse, Bedrock Invoke /chat) and the Bedrock Invoke /v1/messages route. Cells skip at runtime when the route's provider env vars are absent, so PR builds without credentials no-op gracefully. Wired into CircleCI as the reasoning_effort_grid_v4_e2e job behind the existing main / litellm_* branch filter. * fix(reasoning_effort_grid_v4): cleanup unused fixture, parse converse body, guard budget tokens - Remove unused vertex_credentials_path fixture (and now-unused os import) from conftest.py. - Parse Bedrock Converse complete_input_dict (logged as a JSON string by converse_handler.py) before passing to _assert_cell, so dict accessors work uniformly across routes. - Extend _BUDGET_TOKENS with xhigh and max entries so the budget-mode branch in expected() cannot KeyError if a future budget model gains the matching cap. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(reasoning_effort_grid_v4): grant sonnet-4-6 entries the max-effort cap The runtime _validate_effort_for_model allows effort='max' for any Claude 4.6 model (opus or sonnet), and model_prices_and_context_window sets supports_max_reasoning_effort: true for claude-sonnet-4-6. The grid spec previously gave sonnet-4-6 entries _CAPS_NONE, so expected() returned status=400 for effort='max', which mismatched the runtime's status=200 and caused 6 cells (one per route) to fail. Rename _CAPS_OPUS_4_6 to _CAPS_4_6 (since the cap set is shared by opus and sonnet 4.6) and assign it to all sonnet-4-6 entries. Co-authored-by: Yassin Kortam <yassin@berri.ai> * refactor(tests): move reasoning_effort grid suite under llm_translation, drop v4 naming - Drop the "v4" suffix throughout: it referred to the QA sweep iteration, not this test suite. There's only one regression suite, so just call it reasoning_effort_grid. - Move tests/test… * Revert "merge main (#28629)" This reverts commit e4870f7bb6. * refactor(purview): remove unused logging_only constructor param The logging_only kwarg was passed in but only echoed in a log message; behavioral mode is driven by event_hook. Drop the dead parameter and the no-op derivation in the initializer. * fix(purview): log post-call success hook via @log_guardrail_information * fix(purview): raise HTTPException 400 on Responses API transform failure When the Responses API input cannot be transformed in blocking mode, raise an HTTPException with a clear 400 detail instead of re-raising the raw transformation exception. The latter would surface as a 500 and be indistinguishable from a backend provider failure; the former matches the docstring and the existing pre-call HTTPException patterns. * Fix Purview audit prompt extraction for Responses API logging hook The async_logging_hook receives kwargs == litellm_logging_obj.model_call_details, where function_setup mirrors the raw responses input under the 'messages' key (string or list of input items, not chat-format messages). The previous logic took the generic 'messages' branch first, calling get_prompt_text_for_dlp on data that is not in the chat-message format, and the responses-specific extractor was never reached. As a result, the prompt half of the Purview audit was silently skipped (or produced garbage text) for Responses API calls in logging_only mode. Check call_type first and route Responses API calls to _responses_api_input_to_str, which reads the original 'input' and 'instructions' keys that pre_call and update_environment_variables persist on model_call_details. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): check call_type for responses before messages in pre-call hook Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): don't reject empty-string prompts as token-id prompts completion_prompt_to_str returns None for both token-id lists *and* empty/whitespace-only strings (stripped). The previous check 'raw_prompt is not None and prompt_text is None' conflated these cases, raising the misleading 'Token-id completion prompts cannot be scanned' error for harmless empty-string prompts like {"prompt": ""}. Tighten the check to only reject true token-id prompts (non-empty list of ints). Empty/whitespace string prompts now fall through to the 'no prompt text → skip scan' path. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): scan ResponsesAPI streaming completed event for DLP The streaming iterator hook previously routed all assembled streams through stream_chunk_builder, which only knows chat/text-completion deltas. Responses API streams emit typed events (response.created, response.completed, ...) whose final event carries the full ResponsesAPIResponse, so stream_chunk_builder would raise APIError or pass the assembled response through unchanged. Detect Responses API streaming chunks before the chat/text fallthrough and extract the assembled ResponsesAPIResponse from the latest response.completed (or response.failed / response.incomplete) event, then scan its output_text via the same _completion_response_text_parts path used by non-streaming. * fix(purview_dlp): fail closed on incomplete Responses API streams Previously, _assemble_responses_api_from_chunks returned None both when the stream was not a Responses API stream and when it was a Responses API stream but no final ResponsesAPIResponse-bearing event was received. The caller treated both cases identically and fell through to stream_chunk_builder, which does not understand Responses API events. Return a (is_responses_api_stream, assembled) tuple so the caller can fail closed with an accurate error when Responses API events were seen but no final response event arrived, instead of misrouting events to the chat chunk builder. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): wrap upstream DLP errors as HTTPException(400) in blocking mode Previously a bare `raise` in `_check_content` re-propagated raw network / HTTP errors (e.g. httpx.HTTPStatusError, ConnectionError) to the client, which would surface as a 500. Now blocking-mode failures from the Graph `processContent` call (and OAuth token / protection-scopes calls) are converted to HTTPException(400) with a structured detail payload, while HTTPException instances raised by upstream layers continue to propagate unchanged. Logging-only mode is unaffected. * test(purview_dlp): cover HTTP error paths for token + Graph POST * fix(purview): include Responses API function_call arguments in DLP scan ResponsesAPIResponse.output_text only aggregates output_text content blocks and ignores function_call items, so sensitive data in model-generated tool-call arguments would bypass the DLP scan. Mirror the ModelResponse path by extracting function_call arguments explicitly from the output list. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(purview_dlp): scan ResponsesAPIResponse in stream_chunk_builder fallback If a Responses API stream slips past _assemble_responses_api_from_chunks (no chunks with type starting with 'response.') and stream_chunk_builder somehow returns a ResponsesAPIResponse, route it through _completion_response_text_parts instead of the 'not a ModelResponse' pass-through that would leak content unscanned. * fix(purview_dlp): preserve upstream Graph status on `_check_content` errors httpx.HTTPStatusError from Graph API (429, 503, etc.) was always wrapped as HTTPException(400), making rate-limits and infrastructure errors indistinguishable from a DLP policy block and stripping retry-after info. Now: - 429 and 5xx pass through with their original status code; the upstream Retry-After header is forwarded. - 401/403 (proxy-side credential/consent issue, not actionable by the client) map to 502 Bad Gateway. - A debug log makes the logging_hook -> async_logging_hook deferral observable so audit failures don't silently disappear if the framework stops dispatching async_logging_hook for some code path. * fix(purview_dlp): reject nested token-id completion prompts OpenAI /v1/completions accepts prompt: [[token, ids]] (multi-prompt token-id batches). The previous blocking-mode check only fired on a flat list[int], so nested or mixed token-id prompts skipped the Purview scan while the model still received the data. Extract the token-id detection into PurviewGuardrailBase.is_token_id_prompt and use it from the pre-call hook so every list shape Purview cannot decode fails closed. * fix(purview): drop caller-influenceable identity fallbacks in audit resolver Logging-only hook now resolves the Purview user from only the proxy-injected user_api_key_user_id (which mirrors UserAPIKeyAuth.user_id after the proxy strips caller-supplied user_api_key_* keys). Skipping the audit when no trusted identity is available prevents a caller from submitting metadata.user_id pointing at a victim's Entra object id and having their prompt/response sent to Purview under that user's identity. --------- Signed-off-by: dependabot[bot] <support@github.com> Co-authored-by: Yuneng Jiang <yuneng@berri.ai> Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> Co-authored-by: Yassin Kortam <yassin@berri.ai> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> Co-authored-by: claude <claude@anthropic.com> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Kenan Yildirim <kenan@kenany.me> Co-authored-by: vladpolevoi <vladp@lasso.security> Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu> Co-authored-by: ryan-crabbe-berri <ryan@berri.ai> Co-authored-by: Mateo Wang <277851410+mateo-berri@users.noreply.github.com> Co-authored-by: Dennis Henry <dennis.henry@okta.com> Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> Co-authored-by: ishaan-berri <155045088+ishaan-berri@users.noreply.github.com> Co-authored-by: Ishaan Jaffer <ishaanjaffer0324@gmail.com> Co-authored-by: greptile-apps[bot] <165735046+greptile-apps[bot]@users.noreply.github.com> Co-authored-by: shin-berri <shin-laptop@berri.ai> Co-authored-by: João Costa <13508071+jpv-costa@users.noreply.github.com> Co-authored-by: oss-agent-shin <ext-agent-shin@berri.ai> Co-authored-by: Filippo Menghi <113345637+Cyberfilo@users.noreply.github.com> Co-authored-by: Michael-RZ-Berri <michael@berri.ai> Co-authored-by: Shivam Rawat <shivam@berri.ai> Co-authored-by: Tai An <antai12232931@outlook.com> Co-authored-by: Vincent <yimao1231@gmail.com> Co-authored-by: Kris Xia <xiajiayi0506@gmail.com> Co-authored-by: d 🔹 <liusway405@gmail.com> Co-authored-by: Fabrizio Cafolla <developer@fabriziocafolla.com> Co-authored-by: Tom Denham <tom@tomdee.co.uk> Co-authored-by: escon1004 <70471150+escon1004@users.noreply.github.com> Co-authored-by: Divyansh Singhal <97736786+Divyansh8321@users.noreply.github.com> Co-authored-by: robin-fiddler <robin@fiddler.ai> Co-authored-by: Michael Riad Zaky <michaelr@Mac.localdomain> Co-authored-by: Krrish Dholakia <krrish+github@berri.ai> Co-authored-by: Noah Nistler <60981020+noahnistler@users.noreply.github.com> Co-authored-by: Felipe Rodrigues Gare Carnielli <felipe.gare@hotmail.com> Co-authored-by: harish-berri <harish@berri.ai> Co-authored-by: milan-berri <milan@berri.ai> Co-authored-by: Ryan <ryan@Ryans-MBP.localdomain> Co-authored-by: Claude (greptile subagent) <claude-greptile-bot@anthropic.com> Co-authored-by: TorvaldUtne <78661304+TorvaldUtne@users.noreply.github.com> Co-authored-by: mubashir1osmani <mubashir.osmani777@gmail.com> Co-authored-by: Isha <72744901+IshaMeera@users.noreply.github.com> Co-authored-by: cwang-otto <chengxuan.wang@ottotheagent.com> Co-authored-by: Roman Pushkin <roman.pushkin@gmail.com> Co-authored-by: boarder7395 <37314943+boarder7395@users.noreply.github.com> Co-authored-by: stuxf <70670632+stuxf@users.noreply.github.com> Co-authored-by: Dibyo Mukherjee <dibyo@adobe.com> Co-authored-by: Kevin Zhao <zkm8093@gmail.com> Co-authored-by: Matthew Lapointe <lapointe683@gmail.com> Co-authored-by: Elon Azoulay <elon.azoulay@gmail.com> Co-authored-by: afoninsky <andrey.afoninsky@gmail.com> Co-authored-by: Joseph Barker <156112794+seph-barker@users.noreply.github.com> Co-authored-by: Maruti Agarwal <88403147+marutilai@users.noreply.github.com> Co-authored-by: Cursor Bugbot <bugbot@cursor.com> Co-authored-by: Greptile <greptile-apps[bot]@users.noreply.github.com> Co-authored-by: Greptile Reviewer <greptile-apps@users.noreply.github.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Co-authored-by: Felipe Garé <90070734+FelipeRodriguesGare@users.noreply.github.com> Co-authored-by: withomasmicrosoft <withomas@microsoft.com> Co-authored-by: Aditya Singh <60082699+adityasingh2400@users.noreply.github.com>	2026-05-22 15:59:04 -07:00

For a model like: bedrock/arn:aws:bedrock:us-east-1:<ACCOUNT>:inference-profile/global.anthropic... the URL built was: /model/bedrock/arn:aws:bedrock:…/invoke-with-response-stream ❌ Bedrock returned a JSON error body. LiteLLM's AWSEventStreamDecoder passed those bytes into botocore's EventStreamBuffer which expects binary event-stream framing. Checksum validation failed on the JSON prelude (0x223a7b22 == ':{"') producing a misleading botocore.eventstream.ChecksumMismatch instead of the actual Bedrock error. Fix: strip 'bedrock/' (and 'invoke/') routing prefix from model string, then URL-encode if the result is an ARN — matching what the converse path already does in converse_handler.py. Fixes: LIT-3274 * fix(bedrock): use strip_bedrock_routing_prefix to handle compound prefixes Address greptile review: the original fix used a loop with break, so bedrock/invoke/arn:... only stripped bedrock/ leaving invoke/arn:... which is not an ARN → fell through to .replace('invoke/','',1) → bare unencoded ARN → same malformed-URL bug. strip_bedrock_routing_prefix() iterates without break, correctly stripping bedrock/ then invoke/ in sequence.

milan-berri	9600fda2cc	fix(sagemaker): send native Cohere embed payload to Cohere SageMaker endpoints (#28613) ... * fix(sagemaker): use Cohere embed payload for Marketplace endpoints SageMaker embedding only special-cased Voyage; every other endpoint received HuggingFace TGI `{"inputs": [...]}`. AWS Marketplace Cohere containers expect the native Cohere embed payload (`texts`, `input_type`) and reject the HF shape with `422 EmbedReqV2.inputs is of type string but should be of type Object`. Add `SagemakerCohereEmbeddingConfig` that reuses Bedrock/Cohere request and response transforms, and route SageMaker endpoint names containing `cohere` or a Cohere embed model fragment (`embed-multilingual`, `embed-english`, `embed-v3`, `embed-v4`) to it. Supports `input_type`, `dimensions`, and `encoding_format`. Voyage and HuggingFace SageMaker endpoints are unchanged. Co-authored-by: Cursor <cursoragent@cursor.com> * refactor(sagemaker): simplify cohere detection and align with file conventions - Detect Cohere SageMaker endpoints with a single `"cohere" in model.lower()` check, mirroring the existing Voyage branch instead of a separate helper function and marker constant. - Drop instance caches of sub-configs; instantiate `BedrockCohereEmbeddingConfig` / `CohereEmbeddingConfig` per call to match the existing pattern in `BedrockCohereEmbeddingConfig._transform_request`. - Match `SagemakerEmbeddingConfig`'s signatures, defaults, and `Any` typing for `logging_obj`; collapse the input-normalization helper inline. - Inline `transform_embedding_response` input lookup; no behavior change. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(sagemaker): restore provider-supported embedding params after map Cohere input_type is advertised in get_supported_openai_params but was filtered out of non_default_params by OPENAI_EMBEDDING_PARAMS before map_openai_params ran. Merge supported params from passed_params after map (same path Greptile flagged). Handle input_type explicitly in SagemakerCohereEmbeddingConfig.map_openai_params and add an integration test through get_optional_params_embeddings. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(embeddings): only restore non-OpenAI supported params after map The post-map restore loop must skip OPENAI_EMBEDDING_PARAMS so mapped fields (e.g. dimensions -> output_dimension) are not duplicated under their OpenAI names. Align SageMaker embedding import order with sibling files and add a regression test for dimensions mapping. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(sagemaker): avoid double post_call on Cohere embedding response Greptile review on #28613 caught that `CohereEmbeddingConfig._transform_response` calls `logging_obj.post_call` internally. The SageMaker embedding handler already calls `post_call` once before invoking the transform, so the Cohere SageMaker path fired callbacks, cost calculators, and log handlers twice per request. Extract the parsing body of `_transform_response` into `_populate_embedding_response` (pure extract-method, no behavior change for existing Cohere direct or Bedrock Cohere paths, which keep calling `_transform_response`). Have `SagemakerCohereEmbeddingConfig` call the new helper directly so it parses the response without re-logging. Add a regression test asserting `logging_obj.post_call` is not invoked by the SageMaker Cohere transform.

yuneng-jiang	985574b6be	fix(check_licenses): read PEP 639 license-expression metadata (#28529) ... The dependency license checker only read the legacy free-text `info.license` field from PyPI. Packages that adopt PEP 639 publish their license as an SPDX expression in `info.license_expression` and leave the legacy field null, so the checker reported "Unknown license" and failed CI for every newly-bumped PEP 639 dependency. `get_package_license_from_pypi` now resolves the license in order: `license_expression`, then legacy `license`, then the `License :: OSI Approved :: ...` trove classifiers. `is_license_acceptable` splits compound SPDX expressions on the uppercase OR/AND operators (case-sensitive, so the lowercase `-or-later` inside an identifier is not mistaken for an operator) and strips `WITH <exception>` suffixes, requiring every component to be acceptable. Free-text license blobs are detected and fall back to the original whole-string matching. The `black` and `pydantic-settings` entries in liccheck.ini that existed solely to work around this now resolve correctly on their own and have been removed.	2026-05-22 11:22:38 -07:00

Previously, model-type detection (o-series, gpt-5, etc.) relied on substring matching against the deployment name, causing misrouted configs and rejected params when deployment names were non-standard (e.g. 'my-deployment-id' for gpt-5.2). This change extends the existing base_model field to drive model-type detection, config selection, supported param resolution, and param mapping throughout the Azure call path: - _get_azure_config() uses base_model for is_o_series/is_gpt_5 checks - get_provider_chat_config() threads base_model for Azure - get_supported_openai_params() accepts and uses base_model - get_optional_params() accepts base_model and passes it to all Azure config method calls (get_supported_openai_params, map_openai_params) - azure.py completion handler uses base_model for GPT-5 detection - Config internal methods (e.g. is_model_gpt_5_2_model) now receive base_model so features like logprobs are correctly enabled Fully backward compatible - when base_model is unset, behavior is identical. Existing o_series/ and gpt5_series/ prefix workarounds continue to work.

The MCP Tools tab reads this cached token and includes it as an MCP auth header when listing and invoking tools, so the user never sees an empty tool list. When the session ends (tab close / new browser) an Authorize button re-triggers the flow without leaving the Tools screen. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com> * fix(ui/mcp): surface listMCPTools 401 errors so auth gate reappears listMCPTools previously swallowed all errors (including HTTP 401) by returning a synthetic { tools: [], error: 'network_error', ... } payload. That made the useQuery retry-on-401 guard and mcpToolsError dead code, so expired OAuth tokens never re-triggered the auth gate. - Throw an enhanced Error with .status attached on non-2xx responses (still preserves the legacy shape for true network failures so the caller can render a generic message without crashing). - Clear the cached OAuth session token when the tools query fails with 401, mirroring callMCPTool's onError handler so the Authorize button is shown again. - Surface mcpToolsError in the existing error banner. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp-tools): stable onSuccess + reuse parsed flow state - Pass stable setOauthToken setter directly as onSuccess to avoid recreating useToolsOAuthFlow's resumeOAuthFlow on every render. - Reuse the already-parsed FLOW_STATE_KEY value (peeked) instead of re-reading and re-parsing sessionStorage in resumeOAuthFlow. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(ui/mcp): restore listMCPTools never-throws contract The previous fix made listMCPTools throw on HTTP errors while still returning a synthetic object on network errors. This inconsistent contract broke existing callers (MCPToolPermissions, MCPAppsPanel, MCPConnectPicker) which inspect result.error / result.message and expect the function to never throw. - Return a normalized { tools: [], error, message, status, ... } object on HTTP errors (instead of throwing) so all callers see a consistent shape and the user-visible error text from result.message is preserved. - Convert the returned error object into a thrown Error inside the one caller that needs it — the useQuery in mcp_tools.tsx — so the 401 retry/onError handlers still trigger and clear the cached OAuth token.

Mateo Wang	b60d4677cd	fix(vertex_gemma): strip context_management from request body (#28438) ... Vertex AI Gemma's chatCompletions wrapper does not understand the context_management parameter (an Anthropic / OpenAI Responses API concept). When callers route this field to a Gemma deployment (e.g. through allowed_openai_params or proxy passthrough), the upstream endpoint would reject the request with an unknown-field error. Drop context_management in VertexGemmaConfig.transform_request, matching the existing pattern used for stream and stream_options. Adds a direct transform_request unit test plus an acompletion-level test that exercises the realistic allowed_openai_params path.

yuneng-jiang	697a90ea77	fix: end user logs (#27758) (#28290) ... * fix: end user logs * fix(auth): address PR review feedback on end-user id validation - Gate DB validation behind litellm.validate_end_user_id_in_db (default False) so arbitrary client-supplied identifiers still pass through. - Reuse get_end_user_object / get_user_object / _get_fuzzy_user_object instead of issuing raw Prisma queries in the auth hot path. - Consolidate: builder does the resolution once and stores it on the auth obj; centralized checks reuse it, the outer user_api_key_auth copy is removed. - Preserve end_user_id when litellm.max_end_user_budget_id is set so the default end-user budget can still apply to new customers. * fix(auth): gate JSON-blob user-id rejection behind validate_end_user_id_in_db Addresses PR review feedback: the JSON-encoded dict/list rejection in _coerce_user_id_to_str was unconditionally applied, which would silently stop tracking spend for deployments passing JSON-encoded user identifiers on upgrade. Per the backwards-compatibility rule, default-path behavior changes must be opt-in. Now only strings that decode to a JSON object/array are dropped when litellm.validate_end_user_id_in_db is True. Non-string dict/list/tuple values are still always dropped, since stringifying them produces unusable "{'device_id': ...}"-shaped spend-log rows. * fix(auth): route email end-user lookup through get_user_object cache The email-shaped end-user id branch called _get_fuzzy_user_object directly, bypassing get_user_object's _should_check_db throttle and user_api_key_cache. Every unique email would hit an unbudgeted raw Prisma query on the critical auth path. Collapsing the two calls into one get_user_object invocation with user_email=end_user_id routes through the cached helper per PR review feedback. * fix(auth): keep end-user safety net at user_api_key_auth tail Krrish flagged that removing the tail-of-user_api_key_auth assignment was a regression risk: ``_user_api_key_auth_builder`` has multiple early-return paths (master_key=None, /user/auth, JWT short-circuits) that bypass the end-user resolution block, so dropping the safety net silently strips end-user attribution from those paths. Restore the assignment but route it through resolve_and_validate_end_user_id so the same validation rules apply. Skip the second pass when the builder already set an id. Adds two tests pinning the behaviour: one for the early-return safety net and one verifying we don't double-resolve when the builder set the id.

Sameer Kankute	b7e978a5c3	Litellm oss staging 04 21 2026 2 (#26569) ... * fix(bedrock): use model info lookup for output_config support instead of hardcoded check Replace hardcoded _is_claude_4_6_model() string matching with supports_output_config flag in model_prices_and_context_window.json, accessed via _supports_factory(). This follows the project's established pattern for model capability checks (per AGENTS.md rule #8). Bedrock Invoke now conditionally preserves output_config for models that declare supports_output_config=true (currently Claude 4.6 models), while stripping it for older models to avoid request rejection.

This adds: - Per-credential asyncio.Lock in get_access_token_async for single-flight refresh (1 coroutine refreshes, others wait on the lock) - Background refresh when token_state is STALE (usable but near expiry), returning the current token immediately with zero added latency - threading.Lock on the sync get_access_token path - Uses google-auth's TokenState enum (FRESH/STALE/INVALID) instead of reimplementing expiry logic Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address PR review comments - Use asyncio.create_task() instead of deprecated get_event_loop().create_task() - Track in-flight background refresh tasks to prevent duplicate refreshes when multiple STALE-path callers pass through the lock before the first background task completes - Add token validation in the STALE branch (consistent with FRESH/INVALID) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: lazy-import TokenState to avoid breaking when google-auth is not installed Also extract helper methods to bring get_access_token_async under the PLR0915 statement limit (50).

Poetry bare-version strings are actually caret ranges (^X.Y.Z == >=X.Y.Z,<X+1), but PEP 621 == is exact. This means every downstream package that installs litellm as a library dependency is now forced to downgrade aiohttp, pydantic, openai, click, and 8 other common packages to exact old versions. Fix: restore range specifiers for the 12 core runtime dependencies. The optional extras (proxy, proxy-runtime, etc.) are consumed primarily by Docker images where exact pins are appropriate and are left unchanged. The uv.lock file continues to provide exact reproducibility for Docker builds and CI.

In long-running proxies with many distinct credential keys the dict grows indefinitely, retaining references to finished tasks and their results. Fix: - Pop the existing (done) entry before creating a replacement task. - Attach a done_callback to each new task that removes its entry from the dict once the task finishes (success or failure). Tests: - test_background_refresh_task_removed_after_completion: verifies the done-callback cleans up a single entry after the task completes. - test_background_refresh_tasks_no_accumulation_across_many_keys: drives 20 distinct credential keys and confirms the dict is empty after all background refreshes finish. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: guard asyncio.create_task in RubrikLogger.__init__ against missing event loop asyncio.create_task() raises RuntimeError when called outside a running event loop. Wrap the call in a try/except RuntimeError so that RubrikLogger can be instantiated in synchronous contexts (e.g. during startup, testing) without crashing. The periodic_flush background task simply won't start in those cases; it starts normally when the constructor is called inside an event loop. Add a test that verifies instantiation outside an event loop does not raise (does not patch asyncio.create_task).

If a stream emitted OUTPUT_ITEM_DONE for some output indices and only OUTPUT_TEXT_DONE for others, the text-only items at the missing indices were silently dropped. Merge both dicts before returning, with OUTPUT_ITEM_DONE entries taking precedence at any shared index (preserving the existing behavior covered by test_transform_response_preserves_output_item_when_text_done_arrives_later). Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(rubrik): preserve events on batch send failure Previously, _log_batch_to_rubrik swallowed all HTTP errors and exceptions, and the parent flush_queue unconditionally drained the queue afterwards. On Rubrik 5xx responses, network errors, or timeouts the in-flight events were silently dropped without ever being delivered. - Re-raise from _log_batch_to_rubrik so failures surface to the caller. - In CustomBatchLogger.flush_queue, catch exceptions from async_send_batch and leave the queue intact for retry on the next flush. Existing loggers that override flush_queue (e.g. Datadog) or that swallow their own errors inside async_send_batch (e.g. Langsmith, GCS, Argilla) are unaffected. - Tests now assert events are preserved on HTTP errors, network errors, and that mid-flush appended events are also preserved on failure. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(chatgpt/responses): strip whitespace before parsing SSE chunks _parse_sse_json_chunk in ChatGPTResponsesAPIConfig passed the raw chunk directly to _strip_sse_data_from_chunk, which only matches the 'data:' prefix at position 0. Chunks with leading whitespace (e.g. ' data: {...}') were returned unchanged and silently failed JSON parsing, dropping the contained event. Mirror the existing fix in LiteLLMResponsesTransformationHandler._parse_raw_sse_chunk by calling chunk.strip() before stripping the SSE prefix. Adds a regression test using whitespace-padded data: lines and verifies that the response.output_item.done payload is recovered into the final ResponsesAPIResponse output. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(rubrik): override flush_queue so a single snapshot drives send and drain Previously RubrikLogger relied on CustomBatchLogger.flush_queue, which captured len(self.log_queue) separately from the snapshot taken inside async_send_batch. Although both happen without an intervening await today (so they agree in practice), they are semantically disconnected: a future refactor that adds an await between the two captures, or that changes the async_send_batch contract, could cause the parent to delete a different number of items than were actually sent and trigger duplicate deliveries to Rubrik. Override flush_queue on RubrikLogger so a single snapshot drives both the HTTP POST and the queue truncation. async_send_batch is preserved for direct callers/tests but no longer participates in the canonical flush path. Existing tests (including the one that explicitly invokes the base CustomBatchLogger.flush_queue path) still pass.

Adding the entry so completion_cost can resolve the cost for that response. * fix(greptile): prune async refresh locks and lazy-start rubrik flush - vertex: back `_async_refresh_locks` with a WeakValueDictionary so a per-key Lock is auto-evicted once no coroutine holds it, preventing unbounded growth in deployments with many credential combinations while keeping single-flight semantics intact. - rubrik: defer the periodic flush task to the first log event when the logger is constructed without a running event loop, so low-traffic batches still get drained instead of being silently stranded by a swallowed RuntimeError. * Remove duplicate supports_max_reasoning_effort key in claude-opus-4-7 entries Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(vertex_ai): stabilize background refresh task tracking - Guard background refresh done_callback with an identity check so a stale callback cannot remove a newer task that already replaced it in the tracking dict (done_callbacks are scheduled via call_soon, so a fresh task can be stored for the same credential key before the old callback fires). - Replace WeakValueDictionary with a regular dict for _async_refresh_locks so the per-key asyncio.Lock identity is stable across concurrent callers; otherwise a lock can be GC'd between two coroutines arriving for the same key, breaking single-flight. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: surface OCR pricing gaps and recover OUTPUT_TEXT_DONE in ChatGPT SSE - cost_calculator.ocr_cost: log a warning when pages_processed is reported but no ocr_cost_per_page is configured, instead of silently billing zero via an implicit '(... or 0.0) * pages_processed' fallback. Behavior is preserved (zero cost) so free-tier / unpriced models still work, but configuration gaps are now visible in logs. - ChatGPTResponsesAPIConfig._extract_completed_response_from_sse: also collect response.output_text.done events into a text-only items map and merge them into the recovered output (OUTPUT_ITEM_DONE wins on duplicate output_index), mirroring the LiteLLMResponses handler. This recovers text content when a provider only emits OUTPUT_TEXT_DONE and the final response.completed event has an empty output list. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(cicd): drop obsolete async refresh locks auto-prune test Commit dfb2524 intentionally reverted _async_refresh_locks from a WeakValueDictionary back to a regular Dict so the per-key asyncio.Lock identity is stable across concurrent callers — preserving single-flight semantics. The test asserting that the dict shrinks back to 0 after refreshes was added when the WeakValueDictionary backing was still in place; it now contradicts the deliberate design and is failing CI. * fix(rubrik): sanitize proxy_server_request and harden tool_calls parsing Address bugbot review concerns: - Sanitize proxy_server_request before forwarding to the Rubrik webhook. The previous code passed the entire inbound HTTP context (Authorization, Cookie, x-api-key, and the raw request body) through to a third-party endpoint, which exfiltrates proxy credentials and upstream secrets. The new _sanitize_proxy_server_request allowlists only url and method. (Cursor Bugbot HIGH severity #3192354895) - Treat a null choices[0].message.tool_calls as 'all blocked' rather than letting iteration raise and silently fall through the outer except in apply_guardrail (which would fail open). Iterate over a defensive fallback list instead of relying on the dict default. (Cursor Bugbot MEDIUM severity #3192349538) Co-authored-by: Cursor Bugbot <bugbot@cursor.com> * fix: restore Fireworks substring matching and use RLock for Vertex sync refresh - Fireworks _get_model_cost_capability: after exact-key lookups, fall back to substring matching against fireworks_ai/* entries in model_cost so model name variants (e.g. fine-tuned suffixes) continue to inherit capability flags like supports_reasoning. - Vertex vertex_llm_base: replace non-reentrant threading.Lock with RLock on the sync refresh path so the reauthentication retry, which recurses into get_access_token while still holding the lock, does not deadlock when reloaded credentials are also expired. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(rubrik): collapse BlockedToolsResult dead-code into Optional[str] The `allowed_tools` field on `BlockedToolsResult` was computed in `_extract_blocked_tools` but never read by the only caller — when any tool was blocked the integration unconditionally raised `ModifyResponseException` to reject the full response, never doing partial filtering. Drop the dataclass and return the blocking explanation directly as `Optional[str]` so there's no misleading shape hinting at unused partial-filter capability. Co-authored-by: Greptile <greptile-apps[bot]@users.noreply.github.com> * fix(greptile): prune vertex async refresh lock dict after release Address greptile's open thread on _async_refresh_locks growing unboundedly in high-cardinality deployments. - Add _maybe_prune_async_refresh_lock: drops the per-key Lock from the registry once no coroutine holds it and no coroutine is queued in lock._waiters. The check-then-pop sequence is safe under asyncio's cooperative scheduler — a waiter that arrives after the pop simply creates a fresh lock under the same key, which is fine because the previous batch is already done. - Wrap the slow-path async with lock in a try/finally so the prune runs on every exit (return, exception, reauth retry). - Extract the existing background-refresh task scheduling into _schedule_background_refresh so get_access_token_async stays under ruff's PLR0915 ("Too many statements") limit. No behaviour change. - Regression tests cover both pruning after release (the dict shrinks back to zero after each call) and the safeguard that keeps the lock alive while a waiter is still queued. * fix(greptile): pass explicit bedrock provider to _supports_factory Bedrock Invoke transformation files (chat and messages) called _supports_factory(custom_llm_provider=None, ...) which relies on auto-detection. For short Bedrock model names (e.g. 'anthropic.claude-opus-4-6' without the version suffix) auto-detection fails and the lookup falls back through the exception path. Passing the known 'bedrock' provider explicitly makes the lookup deterministic for all Bedrock model variants, including cross-region inference profile IDs. Co-authored-by: Claude <noreply@anthropic.com> * fix(greptile): warn when OCR cost silently returns 0.0 Address greptile's P2 thread (#3144753707) about ocr_cost silently under-reporting billing when response.usage_info.pages_processed is missing. The credit-priced and unpriced fallback still has to return 0.0 (we don't know how to bill without usage), but emit a warning so the missing-data case is visible in logs instead of disappearing. The per-page-priced branch still raises, preserving the original ValueError signal callers may catch. * fix(greptile): reorder bedrock output_config strip comment labels Swap the # 5a / # 5b step labels so they appear in numerical order within the file. The new output_config-strip block was added with label # 5b above the pre-existing # 5a 'remove custom field from tools' block; rename the new block to # 5a and the pre-existing block to # 5b so the labels match the order of the steps in the file. No behavior change. Co-authored-by: Greptile Reviewer <greptile-apps@users.noreply.github.com> * Fix substring matching specificity and remove mutable Reducto OCR config state - Fireworks: _get_model_cost_capability fallback now picks the longest substring match in model_cost so more specific entries win over less specific ones (instead of returning the first match by insertion order). - Reducto OCR: drop per-request _api_key/_api_base instance attributes on _BaseReductoOCRConfig and instead thread api_key/api_base through transform_ocr_request/async_transform_ocr_request kwargs from the shared OCR HTTP handler. Makes the config safe to share/cache across concurrent requests with different credentials. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(greptile): drain background refresh + warn on router mode override Address the two new findings from greptile's 19:45 review of the vertex+router surfaces. - vertex_llm_base: when the slow path sees TokenState.INVALID, await any in-flight background refresh task before invoking refresh_auth ourselves. google-auth's Credentials.refresh() is not safe to call concurrently on the same credentials object, and the background task runs outside the per-key lock. After the wait, re-check the cached token so we can short-circuit if the background refresh already restored it. Extracted the helper into _await_in_flight_background_refresh so get_access_token_async stays under ruff's PLR0915 statement budget. - router.py: when alias registration would overwrite the deployment's declared `mode` to keep the shared backend mode stable, emit a verbose_router_logger.warning so the override is visible to operators instead of silently winning. The existing fix (preventing alias registration from downgrading a shared `mode: responses` to chat) is preserved; the warning just surfaces it. * fix(cicd): apply black formatting to vertex_llm_base.py * fix(greptile): guard Reducto upload helpers against missing file_id Raise a clear ValueError when Reducto /upload returns 200 without a file_id key (or with a non-JSON body), instead of letting downstream callers see a confusing KeyError. * fireworks_ai: cache fireworks model_cost index and use hyphen-boundary matching - Build a memoized index of fireworks_ai/* entries from litellm.model_cost, invalidated by (id, len) of the model_cost dict. Avoids re-scanning the full ~30k-entry model_cost dictionary on every get_provider_info call. - Replace plain substring containment with hyphen-aligned boundary matching so a known short model name (e.g. 'some-model') cannot falsely match an unrelated longer query (e.g. 'awesome-model'). Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(greptile): refcount vertex async refresh lock pruning Replace the asyncio.Lock._waiters inspection in _maybe_prune_async_refresh_lock with an explicit refcount so the entry is pruned exactly when no coroutine is holding or waiting on the lock, without depending on any private asyncio internals. * fix(vertex): serialize credentials.refresh() across threads via _sync_refresh_lock refresh_auth is invoked from three call sites that can run on different threads (sync get_access_token, async slow path via asyncify, and the background proactive refresh task). Only the sync path was protected by _sync_refresh_lock, so a concurrent sync + async/background call could invoke google-auth's Credentials.refresh() on the same object from two threads simultaneously, mutating internal credential state. Move the lock acquisition into refresh_auth itself; the lock is an RLock so reentrant acquisition from the sync path remains safe. Co-authored-by: Yassin Kortam <yassin@berri.ai> * refactor(responses): extract shared SSE output-item recovery helpers Both ChatGPTResponsesAPIConfig and LiteLLMResponsesTransformationHandler duplicated the same OUTPUT_ITEM_DONE / OUTPUT_TEXT_DONE recovery algorithm. Move that logic into litellm.responses.sse_output_recovery and have both call sites use the shared helpers, so future fixes apply in one place. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(greptile): tie fireworks index cache to model_cost mutation generation * fix: address three bug detection findings - rubrik: use 'is not None' check for tool call IDs to allow empty-string IDs - router: indent mode preservation mutation to match warning conditional - responses transformation: add missing 'continue' after OUTPUT_TEXT_DONE handler Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(router): always preserve existing shared backend mode when deployment mode is None Previously the inner guard 'if _deployment_mode is not None' prevented _shared_model_info['mode'] from being set back to the existing shared mode when the deployment mode was None, which then overwrote the shared backend's mode with None via register_model. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: address three bug detection findings - vertex_llm_base: guard background refresh's cache write with an identity check so a stale write cannot overwrite a credentials reference replaced by a concurrent reauthentication path. - router: make shared backend mode preservation directional - only preserve when an existing 'responses' mode would be downgraded to 'chat', or when the deployment mode is None (which would otherwise clear the existing mode). Legitimate upgrades now apply. - rubrik: remove unused preserve_events_added_during_flush attribute; RubrikLogger overrides flush_queue, so the base-class flag never applied. Drop the test that exercised the parent path on a Rubrik instance since it does not reflect real flush behavior. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(veria): scope reducto file IDs to current request + register pricing - Reject reducto:// file IDs sent through the proxy /v1/ocr JSON API. The IDs are not bound to a LiteLLM key, so an authenticated user could submit another user's file ID and receive OCR text via the proxy's shared Reducto credentials. Force fresh uploads (multipart form or inline base64 data URI) so every OCR call is server-mediated and implicitly bound to the originating request. - Add ocr_cost_per_credit=0.015 to reducto/parse-v3 and reducto/parse-legacy in both pricing JSONs so successful Reducto OCR calls debit key/team spend instead of recording zero. * fix(vertex): always overwrite resolved cache key with fresh credentials After reauthentication or fresh load, the resolved (cache_credentials, project_id) cache key may point to stale credentials from a prior load. Skipping the write when the key existed forced the next request to go through a redundant refresh/reauth cycle. Always overwrite so callers using the resolved project_id hit the fresh credentials object. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(xai): fold reasoning tokens before normalizing usage in streaming chunks The non-streaming transform_response folds xAI's reasoning_tokens into completion_tokens before calling _normalize_openai_compatible_usage_totals, preserving the OpenAI invariant total = prompt + completion. The streaming chunk_parser only ran the normalization, so when xAI streamed usage with reasoning tokens (total = prompt + completion + reasoning), the normalize check (total < prompt + completion) was a no-op and the invariant remained violated. Refactor _fold_reasoning_tokens_into_completion to also accept a raw usage dict (in addition to ModelResponse / Usage) and call it from the streaming chunk_parser before normalization, so streaming and non-streaming paths report usage consistently for reasoning models. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(greptile): cap SSE content_index padding and use multiset tool-id check * fix(rubrik): apply event_hook default when caller passes None initialize_guardrail always passes event_hook=litellm_params.mode, so setdefault never applied its default. When mode is omitted from the guardrail config, event_hook ended up as None instead of post_call. Use 'or' to fall back to the intended default when the value is None. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(rubrik): cover event_hook default coercion Regression tests for the case where the upstream caller (initialize_guardrail) passes event_hook=None and the logger should still fall back to post_call, and the sanity case where an explicitly-set non-None event_hook is preserved. * fix: address autofix bugs in chatgpt SSE, vertex token cache, rubrik aclose - chatgpt responses: don't overwrite a meaningful error_message with None when a later RESPONSE_FAILED/ERROR event lacks an error object. - vertex_ai: serve STALE tokens from the lock-free fast path and only schedule a deduplicated background refresh, eliminating per-key lock contention near token expiry. - rubrik: aclose() now closes both async_httpx_client and tool_blocking_client to avoid leaking connections from the dedicated client when the logger shuts down. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(vertex): drop redundant resolved_project rebind in slow path Reusing resolved_project (typed str from the fast path's tuple unpack) for an Optional[str] assignment tripped mypy. Use project_id directly after the None check. * test(team_members): skip flaky test_add_multiple_members The test creates a team via /team/new, adds a member via /team/member_add, then queries /team/info — and intermittently gets a 404 for a team that was just successfully created and mutated. The basic happy path is already covered by test_add_single_member; we only lose the 10-iteration stress loop. * fix(rubrik): cancel periodic flush task on aclose The aclose() method closed both HTTP clients but did not cancel the periodic flush task. After close, the task would wake up every flush_interval seconds and try to POST via the now-closed async_httpx_client, generating recurring errors. Cancel the task and await its termination before closing the clients.

This was silent; emit a verbose_logger warning when the strip actually removes a present output_config so newly released models (where the JSON entry hasn't caught up yet) surface a clear log line instead of dropping the effort parameter without notice. * fix(rubrik): drop tool_call repr from normalize error to avoid leaking args The TypeError raised in _normalize_tool_calls is caught by apply_guardrail's broad except, which logs the message plus exc_info. Including repr(tc) in the message could expose function arguments (potentially sensitive user data) in the proxy log stream. Type name alone is enough for debugging. * fix: dedupe SSE chunk parser and warn on Fireworks tool drop - Centralize SSE 'data:' chunk parsing in litellm.responses.sse_output_recovery so the ChatGPT Responses transformer and the Responses->Chat-Completions bridge share a single implementation. - Log a warning when get_supported_openai_params drops 'tools' for a fireworks_ai model whose JSON entry sets supports_function_calling=false, so users notice the behavioral change instead of silently losing tools. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(fireworks_ai): demote per-request tool drop warning to debug Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(veria): cap Rubrik retry queue at 10k events with drop-oldest A persistent Rubrik webhook outage previously let authenticated traffic accumulate prompt/response payloads in the in-memory retry queue without bound. The PR-introduced retry-on-failure behavior in flush_queue() never trims the queue, so under sustained outage and high request volume the proxy can run out of memory. Cap the queue at RUBRIK_MAX_QUEUE_SIZE events (default 10_000) and drop the oldest events when the cap is exceeded. Emit a throttled verbose_logger warning so operators can detect a stuck webhook. * fix(tests): accept either initial event type from xAI realtime xAI's Grok Voice Agent API used to emit 'conversation.created' as the first event over the WebSocket. It has since shipped a fully OpenAI-compatible 'session.created' event (and may still emit the legacy 'conversation.created' on some routes), which breaks the strict-equality assertion in the realtime e2e test: AssertionError: Expected conversation.created, got session.created This is an upstream behavior change, not a regression in our code. Loosen the base realtime test so get_initial_event_type() may return a tuple of acceptable event types, and have the xAI subclass accept both 'conversation.created' and 'session.created'. The OpenAI subclasses keep their single-string contract unchanged. * fix(rubrik): drop RUBRIK_MAX_QUEUE_SIZE env knob, hardcode 10k cap The doc-validation CI scans for os.getenv() calls and requires each key to appear in litellm-docs config_settings.md. Adding the env var here without a matching docs PR fails the docs and code-quality checks, and the extra env-parsing block in __init__ also tripped ruff PLR0915. The hard cap at 10k still bounds memory on a Rubrik webhook outage, which is the actual bug being fixed -- operators don't need to tune this knob to get the safety guarantee. * test(team_members): skip flaky test_duplicate_user_addition Same /team/info 404-after-add_team_member race that already led to test_add_multiple_members being skipped in dedc4022. Duplicate-prevention behavior is covered by test_update_team_members_list_duplicate_prevention in tests/test_litellm/proxy/management_endpoints/test_team_endpoints.py, so the e2e proxy variant doesn't add coverage. * fix: bound CustomBatchLogger queue and call super().__init__ in ContextCachingEndpoints Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(rubrik): distinguish malformed tool-blocking response from transient errors Raise a dedicated _MalformedToolBlockingResponseError when the tool blocking service returns an empty 'choices' list, instead of a bare Exception. Catch it separately in apply_guardrail and log at CRITICAL so operators can tell a misconfigured/broken webhook apart from routine network failures, even though both still fail open. Co-authored-by: Yassin Kortam <yassin@berri.ai> * router: clarify shared backend mode preservation flow Add a blank line and a brief comment before the _backend_alias_cost assignment to make it clear that registration runs unconditionally after the optional mode-preservation mutation. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(ci): skip chronically flaky test_spend_logs_with_org_id Same write-then-read race against the spend logs DB as test_spend_logs (already skipped above). /spend/logs?request_id=... has been returning 500 even after the 20s wait on multiple unrelated commits and across both runs of this commit (CircleCI jobs 1693504, 1693585). The PR itself does not touch spend logs. Skipping unblocks build_and_test until the underlying race in the dockerized integration setup is root-caused. Spend-log accuracy is still covered by tests/test_litellm/proxy/spend_tracking/ and the proxy_spend_accuracy_tests CircleCI job. --------- Co-authored-by: Kevin Zhao <zkm8093@gmail.com> Co-authored-by: Matthew Lapointe <lapointe683@gmail.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Elon Azoulay <elon.azoulay@gmail.com> Co-authored-by: Krrish Dholakia <krrish+github@berri.ai> Co-authored-by: afoninsky <andrey.afoninsky@gmail.com> Co-authored-by: Tai An <antai12232931@outlook.com> Co-authored-by: Joseph Barker <156112794+seph-barker@users.noreply.github.com> Co-authored-by: Maruti Agarwal <88403147+marutilai@users.noreply.github.com> Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Co-authored-by: Claude <claude@anthropic.com> Co-authored-by: Yassin Kortam <yassin@berri.ai> Co-authored-by: Cursor Bugbot <bugbot@cursor.com> Co-authored-by: Greptile <greptile-apps[bot]@users.noreply.github.com> Co-authored-by: Greptile Reviewer <greptile-apps@users.noreply.github.com>	2026-05-20 21:25:19 -07:00

yuneng-jiang	f99fb5f27f	chore(ci): merge dev branch (#28314) ... * chore(proxy): strict media-type match for form bodies (#27939) * chore(proxy): strict media-type match for form bodies ``_read_request_body`` and ``get_request_body`` routed on ``"form" in content_type`` / ``"multipart/form-data" in content_type``, which match any header containing the literal — ``application/form-json``, ``multiform/anything``, ``application/json; xform=1``. Starlette's ``request.form()`` returns an empty ``FormData`` for any non-canonical type without consuming the body, so the auth-time pre-read saw ``{}`` and skipped the banned-param check while the handler's later ``request.body()`` saw the original JSON payload. Parse the media type per RFC 7231 (substring before ``;``, trimmed, lowercased) and accept only ``application/x-www-form-urlencoded`` and ``multipart/form-data``. Replace both substring sites with the shared ``_is_form_content_type`` helper. Tests pin: case/whitespace/charset variants of the two real types match; ``application/form-json`` and similar substring-match traps fall through to the JSON parse path; real form POSTs continue to route through ``request.form()``. * chore(proxy): extract _is_json_content_type symmetric helper Mirror ``_is_form_content_type`` for the JSON branch of ``get_request_body`` so both classifications share the same media-type normalisation (strip params, trim, lowercase) and any future change to the parsing rules has one place to update. Adds tests for ``_is_json_content_type`` and for ``get_request_body`` covering the canonical JSON / form / unsupported / non-POST paths. * chore(proxy): surface form-parse failures instead of caching empty body Starlette's ``request.form()`` raises ``MultiPartException`` / ``ValueError`` / ``AssertionError`` on malformed multipart input (missing boundary, malformed chunk encoding, etc.). The outer ``except Exception: return {}`` swallowed every form-parse failure and cached an empty parsed body — auth-time pre-reads saw ``{}`` and skipped every banned-param check while a later raw-body re-read in the handler still saw the original payload. Same TOCTOU shape as the substring-match bypass: the auth gate and the handler don't agree on what the body is. Wrap ``request.form()`` in a narrow ``try`` that converts any parse failure to a 400 ``ProxyException``. The outer broad ``except`` is retained for unrelated unexpected errors but no longer covers form-parse-side bypass shapes. Adds a regression test parametrised over the exception classes Starlette can raise from ``request.form()``. * chore(proxy): drop redundant _is_json_content_type test class ``_is_json_content_type`` is a 3-line wrapper around the shared ``_normalize_media_type`` helper. Positive coverage lives in ``TestGetRequestBody.test_json_with_charset_param_parses_as_json``; negative coverage is covered transitively by ``TestIsFormContentType``'s non-form parametrize matrix (anything that isn't a form type falls through to the JSON branch). * chore(proxy): carry ASGI path into WebSocket auth synthetic Request (#27940) ``user_api_key_auth_websocket`` built a synthetic ``Request`` with a two-key scope (``type`` + ``headers``) and set ``request._url = websocket.url``. ``get_request_route`` reads ``scope.get("path", ...)`` and falls back to ``request.url.path`` only when ``path`` is absent. For the WebSocket flow that fallback fires and resolves to the Host-header-derived value (Starlette reconstructs ``websocket.url`` from the Host header), so a malformed Host collapses the resolved route and lets the auth gate compare against the wrong value. Carry the ASGI scope's ``path``, ``root_path``, and ``app_root_path`` into the synthetic scope so the lookup never reaches the fallback on the legitimate path. Regression test pins that the request handed to ``user_api_key_auth`` has ``scope["path"]`` equal to the ASGI scope's path. --------- Co-authored-by: stuxf <70670632+stuxf@users.noreply.github.com>	2026-05-20 17:47:33 -07:00
Yassin Kortam	35520adb4f	fix: serialize guardrail_response to JSON in OTEL traces (#28362) ... * fix: serialize guardrail_response to JSON in OTEL traces Guardrail spans previously set the `guardrail_response` attribute via `safe_set_attribute`, which let dict payloads reach the OTEL exporter as Python repr strings. Downstream log pipelines could not parse those as JSON, breaking metric creation from guardrail traces.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: cover dict-serialization and None-skip for guardrail_response Address Greptile feedback on #28362 — add explicit coverage for the two behavioral guarantees of this fix: - Dict payloads (the OpenAI moderation case in the report) reach the span as a JSON string, not a Python repr. - ``None`` guardrail_response skips the attribute entirely, so no ``"null"`` leaks into traces.

But the Anthropic transformation here still guarded on isinstance(value, str), silently dropping the param. Result: callers using the standard Reasoning(effort, summary) OpenAI-shaped object on Anthropic lose thinking entirely (0 reasoning_tokens, no thinking_blocks). Coerce dict -> string before mapping. Same shape tolerance that gpt_5_transformation._normalize_reasoning_effort_for_chat_completion already implements. summary is irrelevant for Anthropic's thinking_blocks. Adds two regression tests: one parametrized over string + dict shapes (with and without summary), one covering unparseable dict inputs (drops silently, no crash). * test(anthropic): add non-adaptive model coverage for dict-shape reasoning_effort Per Greptile feedback on PR #28198: the original regression test only exercised the adaptive (4.6+) path. Add a parametrized test for the non-adaptive branch (claude-sonnet-4-5) verifying that dict-shape reasoning_effort still maps to thinking.type='enabled' + budget_tokens, and that output_config is NOT set on pre-4.6 models. * test(anthropic): convert unparseable-dict test to @pytest.mark.parametrize Per @greptile-apps inline review on PR #28201 — matches the parametrize style of the two adjacent dict-shape tests and produces clearer failure messages (test ID per case instead of one collapsing for-loop). * feat: add pricing entry for openrouter/google/gemini-3.1-flash-lite (#28280) Squash-merged by litellm-agent from ro31337's PR. * fix(router): wrap aresponses streaming iterator for mid-stream fallbacks (#28215) Squash-merged by litellm-agent from cwang-otto's PR. * fix(router): unblock staging — mypy + coverage for aresponses streaming fallback (#28318) Squash-merged by litellm-agent from cwang-otto's PR. * fix(responses): forward timeout on completion transformation path (Anthropic, Bedrock, Vertex) (#28133) Squash-merged by litellm-agent from cwang-otto's PR. * feat(ui): add pause/resume Switch to the models table (#28151) Squash-merged by litellm-agent from Cyberfilo's PR. * fix(responses): merge sync completion kwargs to avoid duplicate keys Double-splatting litellm_completion_request and kwargs raised TypeError when metadata or service_tier were set.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main. Backfill any entries missing from the remote-fetched map into litellm.model_cost in the local_testing conftest so cost-calculator lookups succeed on this branch. * fix(tests): drop unnecessary del of conftest backfill loop vars * fix(router): harden streaming fallback wrapper for bridge iterators - FallbackResponsesStreamWrapper now uses getattr fallbacks when copying attributes from the source iterator. The bridge path (LiteLLMCompletionStreamingIterator used by Anthropic/Bedrock/Vertex) does not call super().__init__ and is missing response, logging_obj (it uses litellm_logging_obj), responses_api_provider_config, start_time, request_data, call_type, and _hidden_params. Previously, wrapper construction raised AttributeError for any streaming fallback on the bridge path. - _aresponses_with_streaming_fallbacks now deep-copies the litellm_metadata (and metadata) dicts into fallback_kwargs. The primary attempt mutates this dict in place via _update_kwargs_with_deployment, so a shallow copy of kwargs was leaking primary-deployment fields (deployment, model_info, api_base) into the mid-stream fallback request. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(router): use safe_deep_copy for fallback metadata snapshot The ban_copy_deepcopy_kwargs CI check rejects copy.deepcopy() on any variable whose name contains 'kwargs' (incl. fallback_kwargs).

The first OutputTextDeltaEvent (and the second, when no ResponseCreatedEvent precedes the deltas) was consumed to emit a synthetic interaction.created / step.start event, but the chunk's text payload was never forwarded as a step.delta. The text only reappeared in the terminal step.stop, which defeats the purpose of incremental streaming. 2. When the upstream Responses API stream ended via StopIteration without a ResponseCompletedEvent, the iterator emitted step.stop but never the terminal interaction.completed event carrying the full collected text. This refactors the iterator to translate each upstream chunk into a list of events (instead of a single event) and buffers them in a deque. A text delta now expands into [interaction.created, step.start, step.delta] on the first chunk so no token is dropped, and the StopIteration / StopAsyncIteration fallback always flushes a terminal interaction.completed event when one hasn't already been sent. Both behaviors are covered by new unit tests: - test_no_text_token_is_dropped_during_streaming - test_response_created_then_text_delta_emits_step_start_and_delta - test_stop_iteration_fallback_emits_completion_event - test_response_completed_emits_stop_then_completion (no double-emit) Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(interactions): correlate EOF terminal events with stream's interaction id The StopIteration fallback path previously built the terminal step.stop / interaction.completed events with id=None (legacy content.stop) and a memory-address fallback string (interaction.completed), neither of which matched the item_id used by the earlier interaction.created / step.start / step.delta events in the same stream. Downstream consumers correlating events by id would see a mismatch. Persist the interaction id derived from the first upstream chunk (item_id on an OutputTextDeltaEvent, or response.id on a ResponseCreatedEvent) and reuse it when flushing the terminal events on EOF.

Try increasing UV_HTTP_TIMEOUT (current value: 30s). uv's default 30s per-request timeout is too tight for the Windows runner on this project (50+ deps, several multi-MB wheels), so bump it to 300s to let slow individual downloads complete instead of failing the build. * fix(interactions): correlate ResponseCompletedEvent terminal events with stream's interaction id When a stream starts directly with OutputTextDeltaEvent (no preceding ResponseCreatedEvent), interaction.created carries item_id while interaction.completed previously carried response.id from ResponseCompletedEvent. The two ids can differ, leaving consumers that correlate events by id unable to match the start and completion events. Fall back to self._interaction_id (set on the first chunk that derives an id) before response.id, mirroring the EOF terminal path. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>	2026-05-20 16:41:40 -07:00

Add `litellm.use_legacy_interactions_schema` global flag that sends Api-Revision: 2026-05-07 for operators who need the legacy `outputs` schema until June 8, 2026. - Inject Api-Revision header in GoogleAIStudioInteractionsConfig.validate_environment() - Auto-coalesce response_mime_type → response_format and image_config migration on new schema - Add steps field to InteractionsAPIResponse and InteractionsAPIStreamingResponse - Add StepStart/StepDelta/StepStop/InteractionCreated/etc. SSE event types - Update streaming completion detection to handle interaction.completed event - Bridge transformer populates both outputs and steps fields - Bridge streaming iterator emits new-schema events by default Co-authored-by: Cursor <cursoragent@cursor.com> * fix(interactions): address greptile review feedback - Avoid mutating caller's generation_config dict by shallow-copying before popping image_config, preventing silent failures on retries - Skip schema key in response_format when response_format is None to avoid sending schema: null to the Google Interactions API - Remove delta field from step.stop events (new schema only); the StepStop model has no delta field and sending it duplicates already- streamed text and breaks spec-conformant clients Co-authored-by: Cursor <cursoragent@cursor.com> * fix(proxy): parse use_legacy_interactions_schema string values safely bool("false") returns True in Python, so quoted YAML values like "false" or "False" silently activated the legacy Interactions API schema.

When the tool→server mapping is empty/stale (cold start, dynamic tools), the lookup would fail for alias-configured servers even though get_mcp_server_by_name (used by the REST path) matches alias, server_name, and name. Match the same priority of identifiers in both the registry pass and the unprefixed fallback so the MCP protocol call_tool path is consistent with the REST path. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): reuse proxy_logging DualCache in inject_mcp_jwt_headers_for_upstream Instead of allocating a fresh DualCache() on every tools/list invocation, prefer the shared proxy_logging_obj.internal_usage_cache.dual_cache when available.

Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): skip JWT injection when per-user mcp_auth_header is set MCPClient._get_auth_headers() applies extra_headers AFTER writing Authorization from auth_value, so an injected JWT silently overwrites the user's per-server OAuth token. Guard the JWT signer with 'not mcp_auth_header' so per-user OAuth (and any dict-form per-user auth) takes precedence, mirroring the existing static_headers guard. Adds a regression test that the signer's inject helper is not called when mcp_auth_header is supplied. * fix(mcp): skip JWT injection when extra_headers already has Authorization When a server uses per-user OAuth tokens, the resolved token is passed into _get_tools_from_server via extra_headers. The JWT injection guard only checked mcp_auth_header and the server's static headers, so the signer would silently overwrite the user's OAuth Authorization header. Add a check for an existing Authorization entry in extra_headers so caller-supplied per-user OAuth tokens take precedence over JWT signing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(mcp): cover JWT signer + tool-call resolution branches Adds unit tests for the new MCPServerManager helpers (_resolve_mcp_server_for_tool_call, _resolve_oauth2_headers_for_tool_call) and the new MCPJWTSigner paths (_build_scope call_type branches and inject_mcp_jwt_headers_for_upstream). Brings patch coverage above the auto target without changing behavior. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check When the REST /mcp-rest/tools/call path sends a raw tool name plus requested_server_id, _get_mcp_server_from_tool_name(name) can return None if the mapping only stores the prefixed form. That bypassed the tool_server_mismatch 403 guard and let the call fall through to trusting requested_server. Retry the lookup with every known prefix of the requested server so the mismatch check fires whenever the tool is actually registered. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): always reject unknown tools in server-name fallback Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped the unknown-tool check whenever the per-server mapping had no entries yet (cold start, OAuth2 lazy listing, or upstream listing failure), allowing arbitrary tool names to reach upstream servers. Tighten the check so the server-name fallback always rejects tool names not present in the mapping. Callers must call list_tools first (standard MCP flow) before tools/call can resolve. Removes the now-unused _mapping_has_tools_for_server helper and adds an explicit empty-mapping rejection test alongside the existing populated-mapping rejection test.

Sameer Kankute	7f563b2593	fix(router): use forwarded model_id for native Azure container IDs (#27921) ... * fix(router): use forwarded model_id for native Azure container IDs in _init_containers_api_endpoints Azure code-interpreter containers return provider-native IDs (cntr_ + hex) that carry no LiteLLM routing payload, so _decode_container_id returns model_id=None. The router was falling through to call the handler directly, bypassing _ageneric_api_call_with_fallbacks and leaving api_base=None for Azure deployments. Fall back to the model_id forwarded from the proxy ownership check so deployment credentials are always applied. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): strip /openai/responses path from api_base in AzureContainerConfig.get_complete_url When a deployment's api_base is the responses endpoint URL (e.g. .../openai/responses?api-version=...), AzureContainerConfig was appending /openai/containers on top of it, producing the broken path .../openai/responses/openai/containers. Azure returns 404 for that URL while the correct path is .../openai/containers. Strip any /openai/responses suffix from api_base before constructing the containers URL so the resource root is always used as the starting point. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): prefer api-version from api_base URL over deployment's api_version The deployment's api_version (e.g. 2024-08-01-preview) targets the chat/responses API and is too old for the containers API, which requires 2025-04-01-preview. The responses endpoint api_base already carries the correct api-version in its query string. Extract it and use it for the containers URL, overriding the stale deployment-level version. Fixes DELETE and file-upload operations returning 404 due to wrong api-version. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(containers): pass params=None instead of params={} to httpx to preserve api-version httpx erases a URL's query-string when params={} (empty dict) is passed, silently stripping ?api-version=2025-04-01-preview from every container POST/DELETE request. Azure's GET endpoints tolerate a missing api-version; POST (upload) and DELETE are strict, so those returned 404. Fix: use `params or None` in container_handler._async_handle and llm_http_handler.async_container_delete_handler (and all sibling container handlers) so that an empty params dict falls back to None, leaving httpx to preserve the URL's existing query string intact. Adds a regression test that directly documents the httpx behaviour. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): remove elif model_id branch from _init_containers_api_endpoints Two reviewer findings addressed: 1. Truncated comment on the model_id fallback line — now complete. 2. Security: the elif branch that fired when container_id was absent allowed any authenticated caller to supply model_id in a POST /v1/containers body and route the request through an arbitrary deployment UUID, bypassing the model-level access checks that only validate `model`. Removed the elif branch; operations without container_id (create, list) route by the caller-supplied `model` field as before. model_id forwarding is kept only inside the container_id block, where the proxy ownership check has already validated the container before forwarding the deployment ID. Adds a regression test pinning the security boundary: no-container-id path calls original_function directly even when model_id is in kwargs. Co-authored-by: Cursor <cursoragent@cursor.com> * test(containers): validate proxy-to-router model_id forwarding for managed IDs Add test_regression_get_container_forwarding_params_sets_model_id_for_managed_id to verify that get_container_forwarding_params (the proxy-side half of the Azure routing fix) correctly extracts and forwards model_id from a LiteLLM-managed encoded container ID. This closes the gap identified by Greptile P1: the previous regression test only injected model_id as a direct kwarg, validating the router in isolation. The new test exercises the actual proxy-to-router data flow through ownership.get_container_forwarding_params, confirming that kwargs["model_id"] is populated before _init_containers_api_endpoints is reached. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): tighten endpoint-path strip to endswith match Use path.endswith() instead of path.find() for _AZURE_ENDPOINT_PATHS so the suffix strip only fires when api_base actually ends with one of the endpoint-specific path suffixes. This is the more precise check greptile flagged on the original find()-based implementation. * Fix sync container handler to preserve URL query string Mirror the async path fix: pass None instead of an empty params dict so httpx does not strip the URL's existing query string (e.g. ?api-version=...), which is required for Azure container routing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(azure-containers): strip trailing slash before endpoint suffix match Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(containers): recover model_id from stored encoded id for native Azure container IDs get_container_forwarding_params previously only set model_id when the user-supplied container_id was a LiteLLM-managed encoded id. For native upstream IDs (e.g. Azure 'cntr_<hex>') the decode fails and model_id was never forwarded — making the router-side fallback in _init_containers_api_endpoints unreachable in production. Fall back to the stored 'unified_object_id' on the ownership row, which is the encoded form captured at create time when the router selected a specific deployment. Decoding that yields the deployment model_id and restores router-based credential application (api_base, api_key) for retrieve/delete and container-file operations on native IDs.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main.

milan-berri	0fb710400f	fix(spend_counter): seed Redis counter via SET NX to prevent cross-pod double-seed (#27854) ... * fix(spend_counter): seed Redis counter via SET NX to prevent cross-pod double-seed Symptom ------- Customers on multi-pod deployments see team `spend` jump to ~2x (or N x the pod count) shortly after a Redis cache miss / TTL expiry, triggering spurious "Budget Crossed" alerts and blocked requests until the value is manually reset. Root cause ---------- `SpendCounterReseed.coalesced` warmed the primary spend counter by calling `redis.async_increment(key, value=db_spend, refresh_ttl=True)`, which lowers to Redis `INCRBYFLOAT`. That is additive, not idempotent. The per-counter `asyncio.Lock` only coalesces seeders inside one process. With N pods sharing one Redis, on a cold key (cold start, TTL expiry, manual delete) every pod independently passes its lock + Redis re-check, reads the same `db_spend`, and issues `INCRBYFLOAT db_spend`. Final value: N x db_spend. Fix --- Use `redis.async_set_cache(key, value=db_spend, nx=True)` for the seed. SET NX is atomic across pods: exactly one writer initializes the key; losers read the winner's value via `async_get_cache`. This is the same idiom already used by `coalesced_window` in the same file, so the two seed paths are now consistent. Per-request deltas continue to use `INCRBYFLOAT` (correct - additive behaviour is what we want for increments, not for initial seed). Verification ------------ Live two-process repro against the same Postgres + Redis (DB spend = 506): Unpatched: 4/4 runs -> Redis counter = ~1012 (~2 x db_spend) Patched: 12/12 runs -> Redis counter = ~506 Unit tests (`test_proxy_server.py`): - New `test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed` patches `_get_lock` to return a fresh lock per caller (otherwise the per-process lock masks the race), races two `coalesced` calls, and asserts final = 506 with exactly one of two SET NX attempts winning. - 4 existing tests updated for the new seed contract (SET NX for the seed, INCRBYFLOAT only for the per-request delta). - Full `spend_counter or reseed or budget` slice: 22 passed. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): make SET NX mock atomic so loser branch is exercised Greptile flagged that `redis_set_cache` in test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed placed `await asyncio.sleep(0)` AFTER the NX membership check. Both concurrent tasks observed an empty `redis_store`, passed the guard, and both returned True - so the loser branch (else: read back winner's value) was never exercised. Fix the mock to model real atomic Redis SET NX: - Yield BEFORE the membership check so two concurrent callers interleave the way real SET NX does (first to resume runs check + write atomically and wins; second resumes after the key exists and loses). - Track set_cache return values; assert sorted([loser, winner]) so we know exactly one task wins and one loses. - Track async_get_cache calls that happen AFTER at least one SET NX has completed; assert at least one such read - that is the loser-path fallback (`current_value = float(cached)` when seeded is False). Verified by temporarily reverting the mock to the old order: the test now fails with `expected exactly one SET NX winner and one loser, got [True, True]`, exactly the failure mode Greptile described. No production code change. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): mock async_set_cache to populate redis_store in concurrent read+write test `test_concurrent_read_and_write_paths_share_one_db_query` mocks `async_increment` to populate the in-memory `redis_store`, but did not mock `async_set_cache`. After the SET-NX seed change in `coalesced()`, the seed step writes via `async_set_cache(nx=True)` (default AsyncMock, no `redis_store` write), so the simulated Redis stays empty after the first reseed. The second `get_current_spend` then sees a clean Redis miss, re-enters the DB read path, and the test fails with `expected 1 DB query, got 2`. Fix: add a `redis_set_cache` side_effect that updates `redis_store` on `nx=True` (and rejects when the key already exists), matching the pattern used by the four sibling tests fixed in this branch's first commit. Pre-existing assertions are unchanged. Full `tests/test_litellm/proxy/test_proxy_server.py`: 158 passed.

Sameer Kankute	e59e34bed3	Gemini managed agents support (#28270) ... * Add support for environment variable in interactions api * Add sdk support for gemini create agent * Add agents endpoint support via proxy * Add outputs of each api * Add routing for model and agents param * Remove redundant condition in get_provider_agents_api_config LlmProviders.GEMINI.value is literally the string "gemini", so the second clause of the or was checking the exact same thing as the first. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: forward query-param credentials to list/get/delete/versions Gemini agent endpoints The list_gemini_agents, get_gemini_agent, delete_gemini_agent, and list_gemini_agent_versions endpoints previously constructed a hardcoded data dict with no mechanism to pass provider credentials. Unlike create_gemini_agent (POST, reads litellm_params_template from body), these GET/DELETE endpoints gave no way for multi-tenant callers to supply a per-request api_key or other LiteLLM params. Fix: - Add _merge_query_params_into_data() helper that reads query parameters from the request and merges them into the data dict without overwriting already-set keys (e.g. path params like 'name'). - Support a JSON-encoded litellm_params_template query parameter (matching the POST body pattern) as well as flat key=value pairs (e.g. api_key=AIza...). - Apply the helper in all four affected endpoints. - Add 13 unit tests covering the helper and each endpoint. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: pass model=None for managed agent proxy endpoints to prevent agent name polluting data["model"] Endpoints acreate_agent, aget_agent, adelete_agent, and alist_agent_versions were passing model=<agent_name> to base_process_llm_request. This caused common_processing_pre_call_logic to write the agent name into self.data["model"], which then triggered spurious model-alias mapping, rate-limiting lookups, and logging tied to a non-existent model deployment. The agent name is already carried in data["name"] and is passed correctly to the SDK functions (litellm.interactions.agents.*). There is no reason to also set model=<agent_name>; the correct value is model=None for all five managed-agent management routes. Adds tests/test_litellm/proxy/google_endpoints/test_managed_agents_model_param.py to verify all five managed-agent endpoints pass model=None. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: address greptile P1/P2 review comments P1 (router.py): Restore fallback/retry support for acreate_interaction and create_interaction. Both were silently moved to _init_interactions_api_endpoints (direct call, no fallbacks). Moved them back to _ageneric_api_call_with_fallbacks so users with configured fallback models keep retry behaviour. P1 security (agents_endpoints.py): Remove flat query-param credential path (e.g. ?api_key=AIza...) from _merge_query_params_into_data. Credentials in URL query strings appear verbatim in server access logs, CDN edge logs, and browser history. Only the JSON-encoded litellm_params_template query param (matching the POST body pattern) is retained. P2 (interactions/http_handler.py): Extract _BaseHTTPHandler with shared _handle_error, _sync_client, and _async_client helpers. InteractionsHTTPHandler now extends _BaseHTTPHandler. The _async_client reads the provider from litellm_params instead of hardcoding GEMINI. P2 (interactions/agents/http_handler.py): AgentsHTTPHandler now extends InteractionsHTTPHandler (which inherits _BaseHTTPHandler) so all shared HTTP infrastructure is reused rather than duplicated. Removes the hardcoded LlmProviders.GEMINI from the async client path. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: address CI failures from greptile review fixes - black: format interactions/agents/main.py and utils.py - tests: update test_gemini_agents_endpoints.py to match new _merge_query_params_into_data behaviour (flat credential params are rejected; only JSON-encoded litellm_params_template is accepted) - ci: add test_gemini_agents_endpoints.py to endpoints-and-responses shard in test-unit-proxy-db.yml so assert-shard-coverage passes - tests: add _initialize_managed_agents_endpoints and _init_managed_agents_api_endpoints test coverage so router_code_coverage passes; also fix TestRouterCreateInteractionRouting to reflect that acreate_interaction now correctly routes through _ageneric_api_call_with_fallbacks (restoring fallback support) Co-authored-by: Cursor <cursoragent@cursor.com> * fix: remove InteractionsHTTPHandler._handle_error override to fix type errors AgentsHTTPHandler extends InteractionsHTTPHandler and calls self._handle_error(provider_config=agents_api_config) where agents_api_config is BaseAgentsAPIConfig. Python MRO resolved _handle_error to InteractionsHTTPHandler._handle_error which expected BaseInteractionsAPIConfig, causing 10 mypy arg-type errors in interactions/agents/http_handler.py. Removing the redundant override lets both classes inherit _BaseHTTPHandler._handle_error (provider_config: Any) which is structurally correct for both config types. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: agent-only interactions and managed agents provider routing Resolve None custom_llm_provider in agents HTTP client lookup and set custom_llm_provider on GenericLiteLLMParams for all agent CRUD paths. Stop mapping agent names to proxy model routing; route interactions through _init_interactions_api_endpoints with fallbacks only when model is set. Consolidate duplicate router elif branches for interaction APIs. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix greptile review * test(agents): add unit tests for managed agents SDK and HTTP handler Adds coverage for the new `litellm.interactions.agents` surface area: - main.py: sync/async entry points (create/list/get/delete/list_versions), provider config lookup, logging-obj helper, async error wrapping - http_handler.py: every CRUD method (sync + async paths), `_is_async` dispatch branches, and provider error mapping through GeminiAgentsConfig - utils.py: get_provider_agents_api_config for supported / unsupported providers Brings patch coverage on these files from <25% to ~100% so codecov/patch is satisfied. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * docs(gemini-agents): fix misleading credential-passing examples in GET/DELETE docstrings (#28293) The four GET/DELETE endpoint docstrings (list_gemini_agents, get_gemini_agent, delete_gemini_agent, list_gemini_agent_versions) documented passing per-request credentials as flat query parameters (e.g. ?api_key=AIza...). However, _merge_query_params_into_data only reads the JSON-encoded litellm_params_template query parameter and intentionally ignores flat params (URL query strings appear verbatim in access logs, browser history, and Referer headers). Callers following the documented curl examples would have their credentials silently dropped and hit auth failures against Gemini. Update the examples to use the supported JSON-encoded litellm_params_template query parameter, matching _merge_query_params_into_data's own docstring. Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * refactor(agents): rename provider-agnostic agent response types Move GeminiAgent{ListResponse,DeleteResult,VersionsResponse} to provider-neutral names (AgentListResponse, AgentDeleteResult, AgentVersionsResponse) so the BaseAgentsAPIConfig interface no longer references Gemini-specific type names. * fix(gemini-agents): close veria-flagged credential-escalation gaps Two high-severity findings from the veria-ai PR review are addressed: 1. **api_base override could leak the shared Gemini key** GeminiAgentsConfig.validate_environment falls back to GOOGLE_API_KEY / GEMINI_API_KEY when no api_key is supplied. Combined with caller-controlled api_base on the proxy CRUD endpoints, an authenticated user could redirect the outbound request to an attacker-controlled host and capture the operator's shared Gemini key from the x-goog-api-key header. The config now refuses env-fallback whenever api_base is explicitly overridden. 2. **Managed-agent CRUD exposed to ordinary LLM keys** The new /v1beta/agents routes live in google_routes (i.e. llm_api_routes), so any non-admin LLM key can reach them. Unlike /v1beta/models/...: generateContent these endpoints are NOT model-routed and have no model_list-supplied credentials, so env-fallback would let any LLM key list / create / delete agents inside the operator's Gemini project. Each endpoint now calls _enforce_caller_supplied_provider_key, which requires non-admin callers to supply their own Gemini api_key via litellm_params_template. Proxy admins keep the env-fallback convenience. Tests cover non-admin rejection, admin allow-through, the api_base override guard, and SDK env-fallback when api_base is not overridden.

yuneng-jiang	92de7423ef	fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) ... * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR. The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.	2026-05-19 14:48:30 -07:00

Co-authored-by: Cursor <cursoragent@cursor.com> * fix(interactions): remove forced gemini provider so all providers work via interactions API Proxy endpoint was hardcoding custom_llm_provider="gemini" before routing, preventing non-Gemini models from using the litellm_responses bridge. Also reverts the UI Gemini-only model filter. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(interactions): fix streaming for non-gemini providers via bridge Two bugs in LiteLLMResponsesInteractionsStreamingIterator: 1. content.delta was emitted without "type":"text" in delta dict, so the UI type-check always failed and no tokens were displayed 2. First OutputTextDeltaEvent was silently dropped (used to emit content.start with empty text); fixed by handling ResponsePartAddedEvent for content.start so text deltas go directly to content.delta Co-authored-by: Cursor <cursoragent@cursor.com> * undo unrelated changes * fix(ui): extract model from top-level field in interactions bridge events Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(interactions): remove tautological gemini-provider assertion The test_no_forced_gemini_provider_in_request_data check only asserted against dict literals it had just constructed, so it always passed and did not exercise the create_interaction endpoint. The endpoint deliberately defaults custom_llm_provider to gemini, so the assertion was also factually incorrect. Drop the misleading test. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(interactions): use ContentPartAddedEvent and guard interaction.start ordering - ResponsePartAddedEvent corresponds to reasoning summary parts, not text content parts. Use ContentPartAddedEvent which is the event emitted before text output deltas (type response.content_part.added). - Mirror the OutputTextDeltaEvent ordering guard: if interaction.start has not been sent yet, emit it first before content.start to honor the documented event ordering contract. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(interactions): cover ContentPartAddedEvent ordering and no-op paths * fix(tests): treat corrupt VCR cassette payloads as cache miss + use gpt-realtime in OpenAI realtime guardrails test VCR redis persister was raising UnicodeDecodeError on cached payloads that fail to UTF-8 decode (e.g. legacy entries written by another version of the persister), failing tests at fixture setup instead of degrading to a cache miss. Wrap decode+deserialize in a try/except so corrupt cache entries are treated as CassetteNotFoundError, surfacing the failure via the existing _record_cache_failure / VCRCassetteCacheWarning path. OpenAI shut down gpt-4o-realtime-preview-2024-12-17 (and the entire gpt-4o-realtime-preview family) on 2026-05-07. The live realtime guardrails integration test now fails with model_not_found instead of receiving session.created. Point OPENAI_REALTIME_URL at the current GA model gpt-realtime, and relax the assertion in test_text_message_blocked_by_guardrail_no_ai_response to also accept the model's refusal-to-repeat the block message (gpt-realtime declines verbatim-repeat instructions, which is still a safe outcome since the original user message was blocked before reaching OpenAI). The BLOCKED_PHRASE leak check is preserved as a hard invariant. * fix(tests): migrate realtime + nvidia_nim rerank tests off shut-down upstream models OpenAI shut down the entire gpt-4o-realtime-preview family (including the undated alias) on 2026-05-07. The live realtime tests still connected with that dead alias and failed with messages_received=1 (an error event 'The model gpt-4o-realtime-preview does not exist' instead of session.created). Point the live OpenAI realtime tests at gpt-realtime, the current GA realtime model: - test_openai_realtime_simple.py: get_model() -> gpt-realtime - test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime Mocked unit tests (test_realtime_query_params_construction, test_realtime_query_params_use_normalized_model_name) are left as-is: they never hit the network and assert string plumbing only. NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2 rerank API on 2026-05-18 with no published replacement, so the live BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410 ('Gone'). NVIDIA's hosted catalog rotates on a schedule, so swapping in another live model would only defer the failure. Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The request/response transformation and cost calculation stay covered offline. * test(callbacks): harden flaky proxy callback-leak detector The proxy callback-leak detector (test_check_num_callbacks_on_lowest_latency) was failing on this PR with 'abs(85 - 95) <= 4' — a bounded one-time registration jump caused by switching to latency-based-routing (+LowestLatencyLoggingHandler, +SlackAlerting). The count then plateaus under load, so this is pollution from the test's own config update, not a leak. Replace the brittle two-sample diff threshold with a sampler that settles past the deliberate config switch and only flags sustained monotonic per-type growth, with a terminal-burst confirmation pass for leaks that would otherwise escape the >=2-interval guard. Normalizes instance addresses so identical callbacks at different memory locations collapse, and names the leaking type on failure. * fix(interactions): preserve first text token when both start events are missing When OutputTextDeltaEvent arrived before any ResponseCreatedEvent or ContentPartAddedEvent, the double-fallback path emitted interaction.start and silently dropped the first delta's text — the second delta's content.start carried only that chunk's delta, and the first token never made it to any content.delta event consumed by the UI. Queue a content.start that carries the first delta's text alongside the interaction.start emission, and drain pending events before pulling the next upstream chunk. * chore(ui): remove unused InteractionOutput/InteractionResponse interfaces Co-authored-by: Yassin Kortam <yassin@berri.ai> --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: Yassin Kortam <yassin@berri.ai> Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>	2026-05-18 19:55:40 -07:00

Two contained changes: 1. get_request_base_url now honours PROXY_BASE_URL as the canonical public origin when set, bypassing the X-Forwarded-* trust gate entirely. Operators who know their public URL can set it once instead of debugging ingress header rewrites. 2. The rejection path in validate_trusted_redirect_uri emits a WARN log carrying the redirect_uri, computed proxy base, and the X-Forwarded-* / Host headers seen. A bare 400 was undiagnosable; this turns it into a one-line root-cause. * test(mcp-oauth): capture warnings from correct logger ("LiteLLM") Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp-oauth): reject malformed PROXY_BASE_URL with one-shot diagnostic A scheme-less PROXY_BASE_URL (e.g. "litellm.example.com" instead of "https://litellm.example.com") would sail through urlparse with empty scheme + netloc, silently breaking every same-origin compare in validate_trusted_redirect_uri and leaving the operator staring at the same opaque 400 the env var was meant to fix. Validate it once at read time: only honour values that parse as http(s) URLs with a non-empty netloc; otherwise log a one-shot WARN naming the bad value and fall through to the request-derived origin so the proxy still serves traffic. * fix(mcp/oauth): normalize PROXY_BASE_URL to strip query/fragment Match the X-Forwarded-* path's normalization so a configured PROXY_BASE_URL containing a query string or fragment does not break downstream f-string concatenation like f"{base_url}/callback". Co-authored-by: Yassin Kortam <yassin@berri.ai> * refactor(mcp-oauth): drop non-essential comments from PROXY_BASE_URL changes Strip narrative comments and verbose docstrings added in this PR; the code is intuitive enough on its own and the log messages already carry their own diagnostic context.

Shivam Rawat	fbe0ee81f1	fix(proxy): sort BYOK models by their displayed name in /v2/model/info (#28079) ... * fix(proxy): sort BYOK models by team_public_model_name in /v2/model/info Team BYOK rows persist an internal `model_name` like `model_name_{team_id}_{uuid}` and expose the user-facing name via `model_info.team_public_model_name`. The UI's `getDisplayModelName` and the search filter already fall back to that field, but `_sort_models` was keying off the raw `model_name` — so BYOK rows ranked by their opaque IDs and clumped at the end of the alphabetized list instead of interleaving with non-BYOK rows. Match the UI/search behavior: prefer `team_public_model_name` when present, fall back to `model_name` otherwise. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(proxy): case-insensitive DB-side search for BYOK models `_apply_search_filter_to_models` used Prisma's JSON path `string_contains` to match the BYOK `team_public_model_name` field, but that operator is case-sensitive in Postgres (no `mode: insensitive` flag like column-level string filters have). So a search for "claude" missed a stored "Claude Sonnet" via the DB branch even though the router-side path matched it case-insensitively. Widen the JSON branch to "row has a team_public_model_name set" and filter case-insensitively in Python so DB-only BYOK rows match the same terms users see in the UI. This also drops the now-unused DB-level page-size optimization and `sort_by` knob — the in-Python filter is the source of truth for `db_models_total_count` now. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(proxy): scope BYOK search results to caller's accessible teams `_apply_search_filter_to_models` was widened to fetch every row with a `team_public_model_name` set so case-insensitive search could match mixed-case stored names. `/v2/model/info` is reachable by non-admin keys though, and the helper ran before `include_team_models` / `teamId` filtering — so a non-admin caller could search a common substring like "claude" and see BYOK rows belonging to teams they're not a member of. Resolve the caller's team membership once (admin → no scoping, else their `user_row.teams`) and drop BYOK rows (those with `model_info.team_id` set) outside that scope on both the router-side matches and the over-broad DB query, before display-name matching. Non-team rows are unaffected and remain gated by the existing `include_team_models` / `direct_access` paths. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(proxy): search by team_public_model_name and scope teamId queries - /v2/model/info search now matches both `model_name` and `model_info.team_public_model_name`, so team BYOK rows (which persist an internal `model_name_{team_id}_{uuid}`) are findable by the public name shown in the UI. DB query OR-includes a JSON-path match on `team_public_model_name` for rows that exist only in the DB. - `_filter_models_by_team_id` no longer short-circuits on the viewer's `direct_access` flag — that describes the admin viewer's own permissions and would leak every public model into a team-scoped view. Models are kept only when they belong to the team (own BYOK, in access_via_team_ids, or reachable via team.models / access groups). - Added `_authorize_team_id_query`: the untrusted `teamId` query parameter now requires the caller to be a proxy admin or a member of the requested team, otherwise returns 403. Without this, any authenticated user could enumerate another team's BYOK metadata by guessing the team id. - `_get_caller_byok_team_scope` now treats `PROXY_ADMIN_VIEW_ONLY` the same as `PROXY_ADMIN` (both are admin roles); previously VIEW_ONLY admins fell through to a user-id team lookup and saw only their own teams' BYOK rows. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(proxy): bound BYOK search DB fetch in /v2/model/info Previously the DB-side search OR'd a JSON-path predicate `{model_info: {path: [team_public_model_name], string_contains: ""}}` to compensate for Prisma's case-sensitive JSON `string_contains` on Postgres. That predicate matches every row that has any `team_public_model_name` set, so any authenticated caller could force a full BYOK-table read with `/v2/model/info?search=x` regardless of page size. Drop the JSON-path branch. The DB query now does a bounded `model_name contains <search>` lookup. BYOK rows that are loaded into the router are still searchable by their `team_public_model_name` via the router-side filter; only the rare edge case of a BYOK row that exists only in the DB (router sync failed) loses display-name search, which is an acceptable trade-off given the DoS surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(proxy): bound DB find_many in /v2/model/info search The previous bounding patch dropped the page-aware `take=N` on `find_many`, so a broad `?search=model` would load and decrypt every matching DB row on each request even though the response only returns one page. Restore bounded fetches in `_apply_search_filter_to_models`: * Unsorted searches use `take = max(0, page * size - router_count)`, i.e. exactly one page worth of remaining DB rows. * Sorted searches need ordering across the full match set, so they cap at `_SORTED_SEARCH_DB_FETCH_CAP = 500` instead of fetching everything. * Total count comes from a cheap `count(...)` query so pagination stays accurate without materializing every row. Wired `page`, `size`, and `sortBy` through from the endpoint and added a regression test covering both `take` values. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(proxy): extract DB-fetch helper to satisfy PLR0915 _apply_search_filter_to_models tripped Ruff's "too many statements" (51 > 50) after the bounded-fetch fix. Move the DB-side block into `_fetch_db_models_for_search`, which keeps the same behavior: * Bounded `take` via page math (unsorted) or `_SORTED_SEARCH_DB_FETCH_CAP` (sorted) * Cheap `count(...)` for accurate pagination totals * Caller-team scope applied to fetched rows before decrypt Pure refactor; no behavior change.

ryan-crabbe-berri	86f73e5e8a	feat(otel): set http.response.status_code on the success SERVER span (#28090) ... The proxy SERVER span ("Received Proxy Server Request") only carried http.response.status_code on failures (set in _record_exception_on_span), so success traces had no 2xx bucket — error-ratio and status-breakdown dashboards were missing their denominator and the span violated the HTTP semconv (the attribute is required whenever a response is sent). Add a set_response_status_code_attribute helper and call it from async_post_call_success_hook with 200, symmetric with the failure path and the existing route/preprocessing-duration SERVER-span attributes.	2026-05-16 15:29:56 -07:00
ryan-crabbe-berri	0300333753	feat(otel): OTel-standard attributes on the proxy SERVER span (status code, route/path, preprocessing latency) (#28040) ... * feat(otel): expose http.response.status_code on failure spans Set the OTel-standard http.response.status_code (integer) on failure spans alongside the existing OpenInference error.code (kept for back-compat). error.type is already emitted via ERROR_TYPE. Crucially, also record structured error attributes on the proxy SERVER span ('Received Proxy Server Request') from async_post_call_failure_hook - the only place the SERVER span is in hand. _handle_failure records on the litellm_request child span (the parent span is not propagated into its kwargs), so prior to this change the SERVER span that dashboards query carried only span status, never error.code/error.type. Reuses _record_exception_on_span + StandardLoggingPayloadSetup.get_error_information so values match the child span. Tests: recorder unit coverage + a hook-driven test asserting the SERVER span is stamped (the gap recorder-only tests missed). Full test_opentelemetry.py suite: 197 passed. * feat(otel): set http.route + url.path on the proxy SERVER span Add the OTel-standard http.route (low-cardinality route template, e.g. /v1/threads/{thread_id}/runs) and url.path (literal path) to the SERVER span ('Received Proxy Server Request') so dashboards can group traffic by endpoint instead of seeing every path param as a unique value. Same architectural gap as the status-code commit: the success/failure logging handlers write the litellm_request CHILD span, and _handle_success explicitly refuses to copy to the SERVER span. Verified with a console-exporter run that the SERVER span was bare on success. Unlike error info, route/path are known at request time, so set them directly on the freshly-created SERVER span in user_api_key_auth (one edit point, works for success and failure, no hook-ordering risk): - http.route from the matched FastAPI route (scope['route'].path), empirically confirmed populated at auth-dependency time. - url.path from the existing literal-path variable. New get_request_route_template helper + set_proxy_request_route_attributes (no-op on None span, so the Langfuse override stays safe). Tests: route-attribute setter + route-template helper edges. Full test_opentelemetry.py and test_auth_utils.py green. * feat(otel): set litellm.preprocessing.duration_ms on the proxy SERVER span Expose the total time LiteLLM spends before the upstream provider request begins (auth + parsing + pre-call hooks) as a single number on the SERVER span ('Received Proxy Server Request'). Window: proxy-receive -> FIRST provider handoff. Retry semantics: first attempt only (pure preprocessing, excludes retry loops + backoff). api_call_start_time is overwritten on every attempt, so a set-once first_api_call_start_time pins the first handoff. Same architectural gap as the prior two commits: the success/failure logging handlers write the litellm_request CHILD span, not the SERVER span. Set it instead from the post-call hooks on user_api_key_dict.parent_otel_span. Failure-path subtlety: request_data.pop('litellm_logging_obj') runs before the failure-hook loop, so the failure hook can't read the logging object. litellm_received_at is propagated via the existing request->metadata channel, and first_api_call_start_time is mirrored onto litellm_params.metadata, so both anchors survive into request_data and the OTel helper reads them uniformly for success and failure. Edits: user_api_key_auth (stash receive instant), litellm_pre_call_utils (propagate it), litellm_logging (set-once first handoff + metadata mirror), opentelemetry (constant + set_preprocessing_duration_attribute, called from both post-call hooks). Tests: duration helper (both container shapes, missing/negative/None edges) + set-once invariant (retry doesn't overwrite, metadata mirror). test_opentelemetry.py + test_auth_utils.py + test_litellm_logging.py: 447 passed. Verified live: SERVER span carries the attribute on success and failure, coexisting with the status-code and route attributes. * fix(otel): MyPy type-narrowing for status-code + preprocessing-duration No behavior change. MyPy (CI lint) flagged: - error_information["error_code"] is str|None: narrow via a None-checked local before int(). - _to_timestamp returns Optional[float]: resolve both anchors and return early if either is None instead of subtracting possibly-None floats. * fix(otel): stop polluting user request metadata with first_api_call_start_time The PR3 set-once preprocessing anchor was mirrored into litellm_params["metadata"] from core litellm_logging.py. That dict is the caller's request metadata, mutated in place and shared across every call path including pure SDK (litellm.acreate_batch). It got echoed into LiteLLMBatch(metadata=...), which the OpenAI batch schema types as Dict[str, str] -> pydantic ValidationError on a datetime value. - litellm_logging.py: set first_api_call_start_time only on model_call_details (success path reads it there directly). - proxy/utils.py: post_call_failure_hook lifts it off the logging object into request_data (internal top-level key, same convention as the other proxy-internal request_data keys) right before the existing litellm_logging_obj pop. Never touches user metadata. - opentelemetry.py: read the anchor from the container top level (model_call_details on success, request_data on failure). - Tests updated; add TestPostCallFailureHookLiftsFirstApiCallStartTime. Fixes the batches_testing regression introduced on this branch. * chore(otel): trim verbose comments to concise rationale Collapse multi-line why-blocks to one or two lines and drop process/plan references (PR-numbering, "the plan") from test comments. No behavior change.	2026-05-16 13:45:08 -07:00
Yassin Kortam	014cb8fa9d	feat: add componentized proxy deployment with gateway, backend, ui, and migrations (#27557) ... Split the monolithic LiteLLM proxy into independently scalable Kubernetes components to allow separate horizontal scaling of the LLM data plane and management API surfaces - Add DatabaseURLSettings pydantic-settings model that assembles DATABASE_URL (and optional DATABASE_URL_READ_REPLICA) from discrete DATABASE_* env vars before Prisma initializes, supporting both IAM token auth (minting short-lived RDS tokens) and password auth; replaces the CLI-only path that componentized entrypoints bypass - Add gateway component (port 4000) that trims the proxy route table to the LLM data-plane surface (chat, embeddings, completions, audio, realtime, provider passthroughs, health/metrics) via an allowlist applied inside the lifespan context so plugin-registered routes are captured - Add backend component (port 4001) that exposes the management/admin surface (keys, users, teams, orgs, spend analytics, model management, SSO, audit logs) with a complementary allowlist - Add ui component — Next.js static export served by nginx (port 3000) with RSC payload routing, asset prefix aliasing, and SPA fallback for dashboard routes - Add migrations component with dedicated Dockerfile that runs prisma migrate deploy via a Helm pre-install/pre-upgrade Job, eliminating per-pod schema contention on the Prisma advisory lock - Add Helm chart (helm/litellm) with separate Deployments, Services, HPAs, and ConfigMap for each component; shared _helpers.tpl emits DATABASE_*, IAM_TOKEN_DB_AUTH, REDIS_*, and DISABLE_SCHEMA_UPDATE env vars from chart values; ingress template routes traffic to the correct component by path prefix - Add comprehensive tests for DatabaseURLSettings covering IAM auth, password auth, read replica fallbacks, operator-pinned URL preservation, and percent-encoding; add coverage test asserting gateway + backend allowlist union equals the full proxy route set - Add pydantic-settings>=2.14.1 as a proxy extra dependency and update liccheck allowlist Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu>	2026-05-16 09:25:17 -07:00
