test: drop the cwd-relative sys.path.insert calls from the test suite (#37802)
* test: drop the cwd-relative sys.path.insert calls from the test suite

TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.

Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.

Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.

* test: drop the duplicate imports the sys.path sweep exposed to F811

* test(pre-call-utils): restore the os import the new bedrock tests need

test(lint): ban blind pytest.raises(Exception) with ruff B017 (#37731)
* test(lint): ban blind pytest.raises(Exception) with ruff B017

A bare pytest.raises(Exception) accepts whatever the body throws. The TypeError
a refactor introduces satisfies it exactly as well as the rejection the test was
written for, so the crash reads as a pass and the test never goes red.

All 111 existing sites are narrowed here. A runtime probe recorded the concrete
exception each one actually catches, and each site now names that type. Where
the code under test genuinely raises a bare Exception, the site pins a stable
slice of the message with match= instead.

Two sites tell on themselves. The shared responses-API cancel test raises
"custom_llm_provider is required but passed as None" rather than talking to a
provider at all, because cancel_responses takes a provider, not a model. And
test_bedrock_guardrails_with_streaming was the only test in its file still
passing without AWS credentials, because the NoCredentialsError boto3 raised
long before the guardrail ran satisfied the blind raises.

* fix(test): widen the openai batch-dispatch assertion to OpenAIError

The narrowed NotFoundError only holds where OPENAI_API_KEY is set. Without one
the SDK raises OpenAIError while building the client, long before any 404, so CI
went red. OpenAIError covers both and still rejects a TypeError from a refactor.

feat: declarative fallback generalizations for unknown models (#29718)
* feat: declarative fallback generalizations for unknown models

Unknown or newly-released models previously degraded (missed cost lookups,
wrong supports_* flags, broken provider routing) and were patched with one-off
hardcoded regexes scattered across Python. This adds a single data-driven source
of truth: a fallback_generalizations block in model_prices_and_context_window.json
holding ordered, case-insensitive regex rules that map a model name to the
metadata to apply when it has no exact entry.

A new fallback_generalizations module owns the rules and a compiled-regex cache
that is built once and invalidated on reload, so the O(n) scan runs only on a
cache miss. get_llm_provider now routes an otherwise-unknown model via the first
matching rule's litellm_provider, replacing the hardcoded _CLAUDE_PATTERN and
_matches_claude_model_pattern. _get_model_info_helper falls back to a matching
rule's model_info after the exact lookups miss, so get_model_info and the
supports_* helpers resolve unknown models from the same rule. get_model_cost_map
extracts the block out of the returned map, and the integrity check now counts
real model entries (excluding reserved meta keys) so the new key cannot mask a
genuinely shrunk upstream file.

The top level of the file stays a flat map of models so existing litellm releases
that fetch the live file keep working and keep receiving updates; the block ships
in both the root file and the bundled backup. An anthropic-claude rule reproduces
the old future-claude routing and additionally supplies capability flags and a
context window

* refactor(anthropic): derive adaptive-thinking from a version threshold; harden generalizations

Replace the per-minor-version _is_claude_4_6_model / _is_claude_4_7_model substring
matchers with a single _claude_version_at_least predicate that parses the Claude
family version from the model name and compares against 4.6. This covers 4.8/4.9/5.x
without a code change (the old matchers missed 4.8 entirely) while keeping an explicit
supports_adaptive_thinking flag authoritative when present, so there is one source of
truth. The two direct call sites in the chat transformation now route through
_is_adaptive_thinking_model instead of the deleted matchers.

Also address review feedback on the generalizations module: return a copy of the
matched model_info so a future caller cannot mutate the compiled-rule cache, document
that patterns are matched with re.search and must anchor with ^ and $, and reindent
the fallback_generalizations block to the file's 2-space style in both JSON files.

https://claude.ai/code/session_01G8Jro8dPLktwnaaSJwVDpo

* fix(anthropic): surface adaptive-thinking from the cost map; fix date misparse

supports_adaptive_thinking shipped in the model cost map but was never declared
on ModelInfo nor copied during construction, so get_model_info (and the supports_*
factory) silently dropped it for every provider-prefixed or generalized name; only
a bare base entry resolved. Wire it through ModelInfo like the other capability
flags and backfill the flag onto the genuine Claude 4.6/4.7/4.8 entries across
providers so the data, not code, declares the capability. The anthropic-claude
fallback rule also carries the flag (and now accepts a dotted minor, e.g. 4.6) so
an unmapped future Claude degrades to adaptive thinking without a code change.

Tighten the Claude version parser so an eight-digit date suffix
(claude-opus-4-20250514, the non-adaptive Opus 4.0) is no longer read as minor
4.20250514. The cost map stays authoritative; the version check is only a fallback
for provider-prefixed names (bedrock/invoke routes, -v1-less ids) that resolve to
no mapped entry and so cannot be reached by an exact lookup or the bare-name rule.

* fix(anthropic): date-safe adaptive-thinking version fallback, conservative fallback pricing, ruff strict gate

Reconcile adaptive-thinking detection after merging litellm_internal_staging.
Keep the cost-map resolver (_supports_model_capability) as the source of truth and
add a date-safe opus/sonnet/haiku >= 4.6 name version as a fallback for
provider-prefixed ids the cost map cannot resolve (e.g.
bedrock/invoke/us.anthropic.claude-opus-4-6). A two-digit cap on the minor keeps an
eight-digit date suffix from being misread as a minor version, so the dated Claude
4.0 release stays non-adaptive

Price the shipped anthropic-claude fallback rule at the Opus tier so an unknown or
newly released Claude is over-costed rather than billed as free

Drop the module-level global state in fallback_generalizations (PLW0603) in favor of
a small registry object, and switch its annotations plus the new utils helper to
builtin generics (UP006), bringing the ruff strict-rule totals back under ceiling

* refactor(anthropic): drive adaptive-thinking version gate from a declarative rule

Replace the bespoke _claude_version_at_least heuristic with a version-gated fallback_generalizations rule. Unmapped Claude ids now resolve adaptive thinking purely from the cost map: an explicit entry, or the new self-contained anthropic-claude-adaptive-thinking rule that matches opus/sonnet/haiku >= 4.6 (covering 5.x, 6.x and beyond with no code change). New families ship via Price Data Reload instead of a code edit

The rule carries the same Opus-tier pricing as the broad anthropic-claude rule plus supports_adaptive_thinking, and is matched first; the broad rule stays version-neutral, so an unmapped >= 4.6 Claude resolves to full pricing and the adaptive flag from one rule, while a sub-4.6 alias such as claude-opus-4-0 is still priced yet stays non-adaptive. The regex caps the minor at two digits so a dated 4.0 id (...-4-20250514) is never read as a >= 4.6 minor

* refactor(anthropic): dedupe adaptive-thinking rule via declarative extends

The version-gated anthropic-claude-adaptive-thinking rule duplicated the
broad anthropic-claude rule's entire Opus-tier price block because rules do
not merge: first match wins and returns one rule's whole model_info, so the
adaptive rule had to be self-contained.

Add a declarative extends field to fallback_generalizations: a rule names a
parent and inherits its model_info, with its own keys overriding. Inheritance
is resolved once at install time against each rule's raw model_info, so the
adaptive rule now carries only its delta (supports_adaptive_thinking) and
inherits pricing from the broad rule. Runtime matching, provider routing and
gating are unchanged; the broad rule stays anchored and first-match-wins still
holds.

* docs(anthropic): add ignored description key documenting each generalization regex

* fix(anthropic): drop fabricated pricing from the anthropic-claude fallback rule

Per review feedback, the base rule no longer carries input/output/cache costs, and the
adaptive-thinking rule that extends it inherits that no-pricing model_info. Pricing an
unmapped model at a guessed tier reports a confidently-wrong cost without the caller
knowing; dropping it keeps the standard unpriced behavior (zero, not a fabricated
number) so a missing price stays visible. The rules still supply provider routing,
context window, and capability flags, so a brand-new Claude can still be called and its
capabilities (including adaptive thinking for >= 4.6) resolved. Description and tests
updated to match

Litellm oss staging 040626 (#29671)
* fix(azure): apply api_version fallback chain to image edit URL

`AzureImageEditConfig.get_complete_url` only read `api_version` from
`litellm_params`. When callers configured it via `litellm.api_version`
or `AZURE_API_VERSION`, the constructed URL had no `?api-version=` and
Azure responded `404 Resource not found`.

Apply the same fallback chain the Azure chat path already uses in
`common_utils.py`:

    litellm_params > litellm.api_version > AZURE_API_VERSION env >
    litellm.AZURE_DEFAULT_API_VERSION

Adds 5 unit tests pinning each layer of the chain plus a regression
guard for `api_base` that already carries `?api-version=`.

* feat(mcp): core sampling and elicitation flow with security hardening

- Add sampling_handler.py: full MCP sampling/createMessage flow with
  model selection (hint-based + priority-based), auth enforcement,
  budget checks, route restriction gates, and tag policy pre-auth
- Add elicitation_handler.py: MCP elicitation/create relay with
  downstream client capability detection
- Wire sampling/elicitation callbacks in mcp_server_manager.py
  gated behind allow_sampling/allow_elicitation config flags
- Add allow_sampling/allow_elicitation fields to MCPServer type
- Fix session lock deadlock: skip lock for JSON-RPC response POSTs
  (elicitation/sampling replies) with truncated-body heuristic
- Extend client.py with sampling_callback and elicitation_callback
- Security: RouteChecks gate, tag-budget bypass fix, x-forwarded-for
  spoofing fix, Latin-1 header encoding guard
- Add 4 new test modules (model access, priority selection, request
  builder, tool conversion) + update existing MCP tests

* fix(security): run pre-call guardrails before MCP sampling acompletion

Without this, an upstream MCP server with allow_sampling enabled could
send prompts that bypass every guardrail (content filtering, PII
redaction, prompt-injection detection) configured on /chat/completions.

- Call proxy_logging_obj.pre_call_hook(call_type='acompletion') before
  llm_router.acompletion so guardrails fire for sampling sub-calls
- Add HTTPException to the re-raise list so guardrail rejections
  propagate correctly instead of being swallowed as generic errors

* feat(bedrock_mantle): add Responses API support (/openai/v1/responses) (#29490)

* feat(bedrock_mantle): add Responses API transformation config

* test(bedrock_mantle): cover trailing-slash api_base normalization

* feat(bedrock_mantle): export BedrockMantleResponsesAPIConfig

* feat(bedrock_mantle): register gpt-5.x Responses config (gpt-oss unchanged)

* feat(bedrock_mantle): add gpt-5.5/gpt-5.4 Responses price-map entries

* refactor(bedrock_mantle): exclude gpt-oss instead of allow-listing gpt-5 for Responses routing

Frontier OpenAI models on Bedrock Mantle are Responses-only on /openai/v1/responses;
gpt-oss is the legacy family that also speaks chat-completions. Gate by excluding
gpt-oss (which keeps its chat-completions emulation) and defaulting everything else
to the native Responses config, so future frontier models (gpt-6, etc.) route
correctly without a code change. Verified against the live us-east-2 Mantle endpoint:
gpt-oss 400s on /openai/v1/responses while gpt-5.5 400s on both standard paths.

* test(bedrock_mantle): cover supports_native_websocket opt-out

Closes the one uncovered line flagged by codecov on the Responses config.
The assertion documents that Mantle Responses has no realtime/websocket
transport, so realtime routing must not attempt a socket it cannot serve.

* fix(bedrock_mantle): route file_search through emulation instead of forwarding to Mantle

BedrockMantleResponsesAPIConfig inherited supports_native_file_search()
-> True from OpenAIResponsesAPIConfig but never overrode it. Mantle has no
OpenAI vector stores, so a forwarded file_search tool is rejected with a
400 (verified upstream: Tool type 'file_search' is not supported). Opting
out, like the existing supports_native_websocket override, routes the tool
through LiteLLM's file_search emulation instead.

* fix(bedrock_mantle): only route openai.gpt frontier models to Responses

The previous gate excluded gpt-oss and routed every other model to the
native Responses config. But on Mantle only the OpenAI gpt frontier models
(gpt-5.x) are served on /openai/v1/responses; gpt-oss and the non-OpenAI
families (nvidia, mistral, google, zai, ...) are chat-completions only and
400 on that path. Allow-list the openai.gpt- family (excluding gpt-oss)
instead, so chat-only models fall through to the chat-completions emulation.
Verified against the live us-east-2 endpoint: nvidia.nemotron-nano-9b-v2
returns 400 on /openai/v1/responses and 200 on /v1/chat/completions.

* fix(proxy): strip stack trace from HTTP 503 responses (CWE-209) (#28330)

* fix(proxy/cwe-209): strip Python traceback from HTTP 503 error responses

The /cache/ping endpoint included a full Python traceback in its 503 error
response body (inside the ProxyException message), leaking internal file
paths, line numbers, and call stacks to any caller. Two MCP route handlers
in proxy_server.py similarly interpolated str(e) into "Internal server
error" detail strings.

Fix: log the traceback server-side via verbose_proxy_logger.exception()
and omit it from the ProxyException payload / HTTPException detail returned
to clients. Tests updated to assert no "traceback" keyword or frame paths
appear in the 503 body, with a new dedicated regression test.

* fix(proxy/cwe-209): apply Greptile P2 fixes and add MCP exception-path tests

Greptile 4/5 review identified two remaining gaps and Codecov reported
0% coverage on the two MCP handler exception branches:

1. caching_routes.py — str(e) in "Service Unhealthy ({str(e)})" could
   still leak Redis hostnames/IPs; replaced with static "Service Unhealthy".
   HTTPException is now re-raised before the generic handler so the
   "cache not initialized" 503 still reaches callers with its detail.
   Removed the redundant str(e) arg from verbose_proxy_logger.exception()
   (exception() already appends the traceback automatically).

2. tests — two new unit tests cover the exception paths in
   dynamic_mcp_route and toolset_mcp_route that were previously at 0%:
   - test_dynamic_mcp_route_unexpected_exception_returns_500_without_traceback
   - test_toolset_mcp_route_unexpected_exception_returns_500_without_traceback

All 25 tests pass (9 caching + 16 MCP).

* test(caching_routes): restore precise assertion in test_cache_ping_no_cache_initialized

The assertion was weakened to `"Cache not initialized" in str(data)`, which
matches the raw string of the entire response dict and would pass even if the
error moved to an unexpected field or changed structure.

Restore a targeted check on the parsed response: assert the exact string in
the correct field `data["detail"]`, matching FastAPI's HTTPException
serialisation format {"detail": "<message>"}.

* test(caching_routes): restore precise assertion and add CWE-209 no-cache path test

The assertion in test_cache_ping_no_cache_initialized was weakened to
`"Cache not initialized" in str(data)`, which matched against the raw string
representation of the entire response dict. This would pass silently even if
the error message moved to an unexpected field or the structure changed.

Restore a targeted assertion on the parsed field:
  assert data["detail"] == "Cache not initialized. litellm.cache is None"
matching FastAPI's HTTPException serialisation format exactly.

Add test_cache_ping_no_cache_does_not_expose_internals to show the code path
is still working correctly after the CWE-209 fix: verifies that the HTTPException
is re-raised as-is (no traceback, no source paths), and asserts the complete
response structure is exactly {"detail": "Cache not initialized. litellm.cache is None"}.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(caching_routes): restore ProxyException envelope for null-cache 503

The except HTTPException: raise guard (added in the CWE-209 fix) caused
the null-cache HTTPException to escape as FastAPI's {"detail": "..."} shape
instead of the {"error": {...}} ProxyException envelope that callers expect.

Move the null-cache guard before the try block and raise ProxyException
directly so the response structure is consistent with all other /cache/ping
503s, and the except HTTPException: raise guard is only reachable by
unexpected downstream HTTPExceptions.

Update the two no-cache tests to assert the correct ProxyException envelope.

* Update utils.py (#26609)

* feat(pricing): add Snowflake Cortex REST API model pricing (#26612)

* feat(pricing): add Snowflake Cortex REST API model pricing

## Summary

Adds pricing and context window information for 20+ Snowflake Cortex REST API models to `model_prices_and_context_window.json`.

## What's included

- **7 Claude models** (sonnet-4-5, sonnet-4-6, 4-sonnet, 4-opus, haiku-4-5, 3-7-sonnet, 3-5-sonnet) — with prompt caching rates
- **4 OpenAI models** (gpt-4.1, gpt-5, gpt-5-mini, gpt-5-nano) — with prompt caching rates  
- **5 Llama models** (3.1-8b, 3.1-70b, 3.1-405b, 3.3-70b, 4-maverick)
- **1 DeepSeek model** (deepseek-r1)
- **1 Mistral model** (mistral-large2)
- **1 Snowflake model** (snowflake-llama-3.3-70b)
- **2 Embedding models** (arctic-embed-l-v2.0, arctic-embed-m-v2.0)

Each entry includes `input_cost_per_token`, `output_cost_per_token`, `cache_read_input_token_cost` (where applicable), `max_input_tokens`, `max_output_tokens`, and capability flags (`supports_function_calling`, `supports_vision`, `supports_prompt_caching`, `supports_reasoning`).

## Pricing source

All prices are in USD per token, sourced from the official [Snowflake Service Consumption Table](https://www.snowflake.com/legal-files/CreditConsumptionTable.pdf) — Tables 6(b) (REST API with Prompt Caching) and 6(c) (REST API).

## Context

The existing `snowflake/` provider has zero model entries in the pricing JSON, which means LiteLLM cannot track costs for Snowflake Cortex calls. This PR fills that gap.

* fix(utils): copy extra_body before adding unknown params to prevent model config mutation (#29620)

Fixes #29615. In add_provider_specific_params_to_optional_params, the line:

    extra_body = passed_params.pop("extra_body", None) or {}

returns the original dict reference when extra_body is non-empty (truthy).
Subsequent writes like extra_body[k] = passed_params[k] then mutate the
shared model config object held by the router, poisoning /model/info and
all subsequent requests for that deployment.

The or {} short-circuit creates a new dict only when extra_body is falsy
(None or {}), which is why the bug does not reproduce with extra_body: {}.

Fix: wrap in dict() so we always work on a fresh shallow copy.

* fix(gemini/veo): move image from parameters into instances[0]

Veo's predictLongRunning schema puts image (and prompt) on the

The Gemini path was leaving image in params_copy, so it ended up
nested under parameters and the API silently ignored it.

The Vertex path already builds the instance dict explicitly, so this
just aligns the Gemini path with it.

Fixes #29498

* address greptile: unconditional pop + BytesIO test

- Pop `image` from params_copy unconditionally so it never reaches
  GeminiVideoGenerationParameters even when None, removing implicit
  reliance on Pydantic's extra-field-ignore.

  covering the BytesIO path (_convert_image_to_gemini_format) — round-trips
  the base64 to confirm encoding.

* fix(huggingface): handle special token text in embedding usage (#29660)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params (#29655)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params

ToolPermissionGuardrail builds self.rules and the compiled target/pattern
maps only in __init__. The base update_in_memory_litellm_params re-sets raw
attributes via setattr but never rebuilds those maps, so a guardrail updated
in place (PUT /guardrails, or the immediate in-memory sync) keeps enforcing
the construction-time rules until it is reinitialized (PATCH path, periodic
DB poll, or restart).

Extract the compile step into _load_rules and override
update_in_memory_litellm_params to rebuild from it (dict- and model-safe),
re-normalizing default_action / on_disallowed_action. Mirrors the existing
PresidioGuardrail override of the same method. Adds regression tests.

Fixes #29592.

* fix(guardrails): handle dict params in ToolPermissionGuardrail in-memory update

Delegate to super() only for LitellmParams input (the base setattr loop is
model-only); apply the raw-dict case inline. Fixes the mypy arg-type error
and makes the recompile work when the proxy passes the raw DB dict.

* fix(guardrails): preserve tool-permission rules on a partial in-memory update

A partial update (e.g. a LitellmParams whose rules field is None) ran through
the generic setattr, which set self.rules to None, and the recompile was
skipped, leaving the guardrail with no rules. Snapshot the previous rules and
restore them when the update carries no rules; an explicit empty list still
clears them. Adds a regression test for the rules-absent case.

Addresses the Greptile review note on #29655.

* fix(bedrock): stop base_model label from stripping tools/tool_choice (#29621)

* fix(bedrock): stop base_model label from stripping tools/tool_choice

A Router/proxy Bedrock deployment whose model_info.base_model is a friendly
label (e.g. claude-haiku-4-5) silently lost tools/tool_choice: the outgoing
Converse request was built without toolConfig, so the model behaved as if no
tools were provided. Worked in v1.84.0, regressed in v1.85.0, and with
drop_params=true it failed silently.

Two changes compound into the bug. completion() passed model_info.base_model
as the model argument to get_optional_params, so the real Bedrock model id
never reached supported-param resolution; and get_supported_openai_params
resolved the provider config's params from base_model or model, letting the
label fully replace the real model. For Bedrock the label resolves to no tool
support, so tools/tool_choice were dropped before transformation.

completion() now keeps model as the real deployment model and threads the
resolved base_model (kwarg or model_info) through separately, and
get_supported_openai_params treats base_model as additive: it returns the
union of the params supported by model and by base_model. A hint can only add
capabilities, never strip ones the real model already exposes, which also
preserves the original base_model behavior from #27717 and Azure's base_model
driven model-type detection.

Fixes #29618

* test(main): make base_model param test robust to new parametrize cases

Restore an explicit per-case expected_model_param literal instead of
hardcoding the gemini id, so a future case with a different model can't
produce a misleading assertion failure.

* fix(fireworks_ai): pass response_format json_schema through unchanged (#29606)

FireworksAIConfig.map_openai_params was rewriting the OpenAI strict
`{type: json_schema, json_schema: {name, strict, schema}}` shape into
`{type: json_object, schema: ...}` before sending to Fireworks, dropping
`strict` and `name` and changing the `type`. Per Fireworks' docs json_object
means "force any valid JSON output (no specific schema)", so the schema
constraint was effectively dropped and grammar-guided decoding never ran;
model output silently violated the schema.

The rewrite landed in #7085 (Dec 2024) when Fireworks did not yet accept
native json_schema. Fireworks accepts the OpenAI strict shape natively now,
so the rewrite has become a regression.

Removes the rewrite. Passes response_format through unchanged. Updates the
existing test_map_response_format to assert pass-through. Adds focused
regression tests in tests/test_litellm/ covering preservation of type,
strict, name, and schema body, plus that json_object alone still works.

When a test_custom_llm.py test runs first in the same xdist worker, provider_list contains a str and calling .value on it raises AttributeError. Iterate the immutable LlmProviders enum instead, which is deterministic and what the check intends.

* fix(mcp): depth-aware JSON-RPC response detection and neutral speed-priority fallback

Replace the flat substring check in the truncated-body routing path with a
top-level-key scan so a JSON-RPC response whose result payload nests a
"method" field is still detected as a response and skips the session lock,
removing a deadlock against the in-flight tool call awaiting it.

Drop the inverse max_output_tokens speed proxy when no model exposes
output_tokens_per_second; context-window size does not track latency, so a
neutral score avoids biasing speedPriority toward the smallest-context model.

* fix(guardrails): make ToolPermission rule reload atomic on invalid regex

_load_rules appended each rule to self.rules before compiling its regex, so an
invalid pattern raised mid-loop after the bad rule was already live but without
a _compiled_rule_targets entry. _matches_regex reads a missing compiled target
as a None pattern and returns True, turning the bad rule into a match-all that
silently applies its decision to every tool. Via update_in_memory_litellm_params
(PUT /guardrails) this corrupted the live guardrail.

Build the parsed rules and compiled maps into locals and swap them in only after
every regex compiles, and restore the previous ruleset if a live update is
rejected, so an invalid regex now fails the update without leaving the guardrail
enforcing a broken policy.

* test(mcp): cover sampling conversion, model resolution, and elicitation relay paths

The MCP sampling and elicitation handlers shipped with partial test
coverage, leaving the response-to-MCP conversion, the model resolution
fallback chain, completion-kwargs assembly, guardrail routing, and the
entire elicitation relay untested. That pulled the PR's diff (patch)
coverage below the codecov threshold even though overall project
coverage rose.

Add focused unit tests for _convert_openai_response_to_mcp_result,
_convert_mcp_tools_to_openai, _convert_mcp_tool_choice_to_openai, image
and audio content conversion, the hint-matching and fallback branches of
_resolve_model_from_preferences, _build_completion_kwargs, the router and
guardrail-rejection paths of _run_guardrails_and_call_llm, the
handle_sampling_create_message success and error-propagation flows, the
marker-hoisting fallback for tool content on unexpected roles, and the
elicitation form/url/generic relay together with its decline paths

[internal copy of #29232] feat: route future Claude models to Anthropic provider via pattern matching (#29239)
* feat: route future Claude models to Anthropic provider via pattern matching

Add pattern-based matching for Claude model names so that future models
(e.g., claude-opus-4-9, claude-sonnet-5-0) are automatically routed to
the Anthropic provider without requiring model_prices_and_context_window.json
updates.

The pattern matches: claude-{opus|sonnet|haiku}-{major}-{minor}[-YYYYMMDD]

https://claude.ai/code/session_017asCVDN5jBFMBcZRjiQR6C

* fix: don't hard-code the tier names

Co-authored-by: greptile-apps[bot] <165735046+greptile-apps[bot]@users.noreply.github.com>

* style: move import re to module level (PEP 8)

Move `import re` from inside the module body to the top-level imports
section, following PEP 8 style guidelines that all imports should
appear at the top of the file.

https://claude.ai/code/session_01Dt8fzn81eYMfxu1MoBa5hN

* test: fix claude-mini-4-5 assertion to match generic-tier pattern

The pattern intentionally accepts any [a-z]+ tier (see f835f84) rather
than a hard-coded opus|sonnet|haiku list, so claude-mini-4-5 routes to
anthropic and the old 'is False' assertion was wrong. Replace it with a
positive test that locks in the generic-tier behavior and guards against
a regression to hard-coded tier names.

* style: collapse _CLAUDE_PATTERN to one line (black)

Black 26.3.1 (CI) collapses the re.compile call onto a single line since
it fits within the line limit. Fixes the failing lint check.

c75f0c0566 test: drop duplicate openrouter prefix-strip test
The multi-segment case (openrouter/<provider>/<model> → <provider>/<model>)
is already covered by tests/test_litellm/llms/openrouter/test_openrouter_provider_routing.py
in internal_staging, with broader coverage including double-prefix native
models, wildcard deployments, and the bridge double-call scenario.
Keeping a duplicate in tests/local_testing/ adds maintenance load with no
extra coverage.

232464e151 test: drop incorrect openrouter native-prefix test
The removed test asserted that get_llm_provider(model="openrouter/auto")
should return model="openrouter/auto" with the prefix preserved. That
contract is wrong: the LiteLLM convention strips one "openrouter/" prefix,
so a native OpenRouter model is reached via "openrouter/openrouter/auto"
(double-prefix) which the wire send as "openrouter/auto" — the ID the
OpenRouter API expects for natives. E2E checks against api.openrouter.ai
confirm this is the correct routing convention for all native models
(auto, bodybuilder, free, pareto-code).

Litellm fix update bedrock models (#24947)
* update bedrock models in tests

* updated more tests and model_prices_and_context_window

* fix model id and pricing

* replace more sonnet models

* update tests

* git push

* update pricing

* flaky total cost

* monkey patch

* relax the cost change

* chore: move cost/pricing changes to bedrock-cost-fixes branch

* chore: split Bedrock file-api beta stripping to separate branch

Removes strip_unsupported_file_api_betas_for_bedrock_invoke from this branch;
see litellm_bedrock_invoke_strip_file_api_betas for that fix.

ad07d7faad fix: strip 'openrouter/' prefix from model names (#24234)
Remove early return in get_llm_provider_logic.py that prevented
the 'openrouter/' prefix from being stripped. The early return was
intended for 'native OpenRouter models' like 'openrouter/free',
but no such models exist in the model registry — all OpenRouter
models are multi-segment (e.g. 'openrouter/anthropic/claude-3.5-sonnet')
and need the prefix stripped before being sent to the OpenRouter API.

This regression was introduced in v1.82.3 and caused 400 Bad Request
errors for all OpenRouter models.
