fix(streaming): keep merged think tags balanced and split SSE lines only on CR/LF (#48755)
* fix(vertex_ai): split Gemini SSE lines on CR/LF only so U+2028 in text keeps the stream

The Gemini and Vertex AI streaming path read the SSE body with httpx
iter_lines()/aiter_lines(). Those follow str.splitlines(), which also breaks
on U+0085, U+2028, U+2029, \x0b, \x0c and \x1c-\x1e. JSON leaves U+0085,
U+2028 and U+2029 unescaped inside strings, so a data: line whose text holds
one of them was cut in two. The tail is not a data: line and the head never
parses, and the accumulate-and-retry fallback then carries the unparsed
prefix forward, so every later event is appended to it and the stream ends
with no more content and no usage.

SSE lines end only at CRLF, LF or CR. The new iter_sse_lines/aiter_sse_lines
split decoded text on exactly those, treating a CR at the end of one chunk and
an LF at the start of the next as one break. The first request and every
long-decode hop now read through them.

* fix(streaming): keep merged think tags balanced and split shared SSE lines only on CR/LF

Close an open <think> block on the first content or tool-call delta and at stream end, reopen it when reasoning returns, and route the shared chat completions stream through the SSE line splitter so U+2028 and U+2029 inside JSON no longer drop chunks.

* fix(streaming): exact-match the SSE [DONE] marker in BaseModelResponseIterator

* fix(streaming): split every SSE reader on CR/LF only and keep the logged think block closed

Switch the remaining httpx stream readers (Anthropic chat, Google GenAI,
Interactions, Codestral, openai_like, Predibase, LangGraph, Vertex Agent
Engine, A2A providers, Azure AI agents, sandboxes, the A2A endpoint, and
others) from iter_lines/aiter_lines to iter_sse_lines/aiter_sse_lines, so a
raw U+2028 or U+2029 inside a JSON string no longer splits an event.

Keep the chunk that closes a think block in the logged and cached response
when a stream ends without a finish_reason, close the block before a legacy
function_call, and make sync Codestral FIM streaming send stream=true and use
the text-completion-codestral stream parser.

Test fakes that only mocked iter_lines now stream real httpx bytes and
assert the content they feed in.

* fix(streaming): split buffered SSE parsers only on CR and LF, shard the codestral tests

Buffered SSE and JSONL parsers used str.splitlines(), which also breaks on
U+2028, U+2029 and U+0085 that JSON allows raw inside strings. They now use
split_sse_lines from sse_lines.py, which also gains a str.split fast path.
Adds tests/unit/llms/codestral to the unit workflow shard.

* fix(streaming): keep U+2028 in restamped Anthropic frames and fold CRLF before splitting SSE lines

* test: type the new stream tests, drop a comment, and benchmark the SSE line splitter

* test: type the iterator class parameters in the line-separator stream tests

* fix(responses): stream tool call arguments opened in a text chunk

* fix(responses): hold a tool call that shares a chunk with text until the text ends

* test: type the a2a SSE handler helper and the sandbox fake responses

fix(llms): join api_base and route with one shared helper (#47535)
* fix(llms): sanitize trailing slashes in provider get_complete_url

* test(llms): move trailing-slash url tests into each provider's mapped unit file

* fix(llms): strip trailing slashes in Perplexity search and Ollama embedding URLs and run the Topaz tests in CI

* fix(llms): strip trailing slashes in search, DashScope, VolcEngine, GigaChat and Gradient AI URL builders

* fix(fastcrw): strip a trailing slash from api_base and expect one slash in the GigaChat tests

* fix(gigachat): strip a trailing slash from the pass-through api_base

* fix(llms): join api_base and route with one shared helper

A deployment api_base that ends in / made several get_complete_url builders emit a double slash, which Envoy and other gateways answer with 404. Add join_api_base in url_utils and use it in those builders, with a regression test that drives every get_complete_url under litellm/llms with a trailing-slash api_base

* refactor(llms): move per-provider api_base strips onto join_api_base

Use the shared join_api_base helper in the search, chat, embedding, image variation, GigaChat and VolcEngine URL builders instead of a per-provider rstrip and suffix check, so one helper owns the single-slash join

* ci: run the trailing-slash URL builder test in the llms shard

* test(integration): cover trailing-slash api_base across provider URL builders

Wire cells for chat, streaming, messages, responses, embeddings, search and pass-through with and without a trailing slash, an owned-proxy module for the flag-gated providers, env bases and a worker kill, two chaos bursts, and a Topaz SDK cell

* fix(llms): send every provider route through join_api_base

Every place under litellm/llms and litellm/main.py that joined a caller-settable api_base with a route by concatenation or f-string now goes through join_api_base, so an api_base with a trailing slash sends the same upstream path as one without it

Routes made only of a caller-supplied id, model, or passthrough path stay on a plain join over an already normalized base, because the helper's suffix dedup would turn a lookup by id into a list or create call

The sweep test now also reaches the factory-made JSON provider builders, and a new loopback test drives the public entrypoints with an api_base ending in /gw/ and checks that every request path keeps /gw/ with no double slash

* fix(llms): keep the route skip only where a builder already had it

join_api_base is a pure join again. The new ensure_api_route skips the route only when the URL path
already ends in it, and it is used only where the merge base or the trailing-slash test PR head
already skipped. Evals cancel, Predibase, and Azure AI threads append their route again, EdenAI
model listing and Gemini RAG ingestion join through join_api_base, and Azure AI Anthropic checks the
path so a host named anthropic-* builds /anthropic/v1/messages

* fix(azure_ai): read /anthropic from the URL path when building the count_tokens URL

* test(llms): run the Gemini RAG trailing-slash case through aingest

The sync ingest wrapper needs a current event loop, which an earlier async test in the same worker clears

* test(llms): cover the Azure realtime, Bedrock rerank, and oobabooga joins with a trailing-slash api_base

* test(integration): cover api_base joins across providers, query strings and named hosts

* feat(url_utils): add join_api_base and ensure_api_route helpers

* fix(url_utils): keep the scheme slashes when a stripped suffix was the whole host

join_api_base and ensure_api_route now keep the // of a base left with only a scheme,
so http://v1 with /v1 stripped joins to http://v1/files as before. The Azure v1 client
base_url goes through ensure_api_route so a base ending in /openai/v1 no longer doubles it

* fix(azure_ai): build the count_tokens URL from the messages URL

* fix(azure_ai): match anthropic as a whole path segment in the messages URL

* fix(llms): keep main's Azure AI anthropic match and non-string Bedrock endpoints

Azure AI chat and messages go back to cutting the base at the first
/anthropic, as on main, and count_tokens keeps its path check, so a
gateway path like /anthropic-proxy builds the same URLs as main. A base
that already ends in /v1/messages still gets count_tokens next to it.

A non-string aws_bedrock_runtime_endpoint (an httpx.URL VPC endpoint) is
used as its text again in AgentCore, Bedrock responses and the RAGFlow
base, instead of falling back to the default host.

get_volcengine_base_url and GigaChat's get_api_base strip a trailing
slash again for outside callers. The cache-hit wire test is skipped as a
known proxy bug, since one cache hit writes two cache_hit spend rows.

* fix(llms): drop a slash before the api_base query and tighten the route test checks

* test(llms): annotate new test locals as Final and flatten the builder generator

* fix(url_utils): keep a scheme-only api_base hostless so it fails before sending

* test: migrate selected llm translation contracts

* test: migrate anthropic completion translation tests

* test: migrate bedrock and cohere translation tests

* test: tighten bedrock translation migration

* test: migrate azure and openai model translation tests

* test: migrate openai and small-provider translation tests

* test: migrate gemini and vertex translation tests

* test: migrate optional params and rerank translation tests

* test: migrate huggingface, json and openrouter translation tests

* test: fix openrouter integration expectations

* test: migrate ovhcloud, prompt and small provider translation tests

* test: split reasoning effort grid into unit and e2e

* test: migrate router and realtime guardrail translation tests

* test: migrate google interactions translation tests

* test: migrate a2a, evals, skills and hosted vllm translation tests

* test: remove remaining llm translation suite

* test: tighten migrated llm translation unit tests and land missing rows

Restores rows the first pass dropped or weakened (bedrock agentcore and openwebui thinking stream, anthropic prefix, citations and tool_choice, azure agents handler, huggingface bare api_base, optional params num_retries, alternating roles, rerank response type), replaces truthiness and call-count checks with whole-value assertions, and moves tests to the mirror file of the code they cover

* test: move cohere, databricks, fireworks and gemini rows to mirror files over mocked HTTP

Restores three TestCohereV2Transform methods the first pass nested out of collection, replaces direct transform calls with respx-backed completion calls, and drops the databricks and fireworks files that sat outside their mirror paths

* test: close lost-intent gaps found in review of the llm translation migration

Points the hosted-mock guard at the triton test's new integration path, restores exact rerank result assertions for infinity, drops the reasoning e2e fallback that passed for any multi-line answer, and adds the mixtral invoke system prompt variants, eval deletion, and async pdf url download that the legacy suite exercised

* test: assert provider acceptance in the reasoning effort e2e

The live half of the split grid proves each route accepts reasoning_effort. claude-fable-5-1 on the direct route answers without surfacing reasoning content, so a reasoning-presence check either fails on head or needs a fallback that passes for any answer. Wire shape stays covered by the unit grid

* test: cover async and stream-end paths the legacy translation suite exercised

Adds async variants for bedrock converse file and thinking content, bedrock embedding timeout and region resolution, interaction stream termination and success logging, xai reasoning token folding, and bytes chunks with a prefix before data:. Also scopes the vertex safety settings global in test_vertex_safety_settings with monkeypatch so it stops leaking into gemini request bodies on the same worker

* test: type the new llm translation e2e calls and mark moved fixture dirs as packages

* test: name the reasoning effort e2e models as module constants

* test: assert reasoning content, register the new gemini coverage ids and give the guardrail config e2e a unique name

* test: block the prompt the shared guardrail denies and drop the reasoning presence check

* test: drop the duplicate litellm import left by the main sync

test: move the unit half of 126 mixed legacy files into tests/unit (#45090)
* test: move the unit half of 126 mixed legacy files into tests/unit

* test: restore litellm globals that moved tests set

* test: finalize migration test cleanup

* test: restore original bodies of moved legacy tests

The move into tests/unit had rewritten 612 test bodies, and some of the rewrites dropped assertions. Each moved test now carries its original body from the legacy file, with only the imports, helpers, fake provider credentials and monkeypatched env it needs to run under tests/unit

test_timeout_streaming goes back to tests/local_testing because it needs the fake OpenAI endpoint server. The image payload fixture moves with its only user, and two tests that leaked global state (a registered model cost entry and queued logging tasks) are now isolated

* test: drop module imports shadowed by restored local imports

* test: assert on LiteLLM output in no-assertion moved tests and isolate leaks

Twenty no-assertion candidates get one assertion on the value LiteLLM returns, with the original lines unchanged. Four tests go back to their legacy files because they only check types or imports, write into the working directory, or cannot assert without a body change

Two moved tests leaked globals into later tests in the same worker, so monkeypatch fixtures now restore the retry-after header parser and the end user cost tracking flags

* test: drain queued logging tasks before the Phoenix span test

The moved Phoenix test counted spans from logging tasks that earlier tests had queued, so the drain fixture moves to tests/unit/conftest.py and both it and the Datadog batch test use it. test_factory_function goes back to its legacy file because its returned wrapper calls the real Assistants API and cannot be asserted on without a body change

refactor(types): replace Any with proven types in 157 files (#44798)
* refactor(types): replace Any with proven types in 299 files

Clears 871 basedpyright Any errors (reportAny 6,703 to 6,240, reportExplicitAny 1,651 to 1,243) without adding a cast, an ignore or a suppression, and without touching any budget file

Most edits are annotation-only: a parameter, return or local goes from Any to object, Mapping[str, object] or the concrete type the value always held. Fourteen files validate untyped JSON once where it enters, through a module-level pydantic TypeAdapter or model_validate, and then use real types

No HTTP status, error type or response shape changes. Mistral speech and fal.ai Bria image generation now report a pydantic ValidationError instead of an AttributeError when the provider answers 2xx with a body that is not a JSON object

* refactor(types): make the config locals fix effective and trim no-op edits

The Mapping[str, object] annotation on `locals().copy()` removed no error,
because the checker narrows the variable back to the dict[str, Any] the call
returns. 21 provider config constructors now build the same copy with
dict(locals()), which the checker infers as object values under that
annotation, so each file loses one reportAny.

The same annotation is reverted in 31 other config files where it stayed a
no-op, together with the tests that were added only to cover those lines, and
the one MCP server manager line that no CI coverage shard executes is
reverted too. The pull request drops from 345 to 297 changed files.

* refactor(types): accept only int in the proxy state setter

get_proxy_state_variable is annotated to return int, but
set_proxy_state_variable still took Any, so the checker could not hold
callers to the type the getter promises. The setter now takes int, which is
what its only caller already passes.

* refactor(types): index the proxy state key so the getter returns int

* refactor(types): keep public annotations and provider error text unchanged

Restore every public return, public method parameter, public attribute and exported
alias to its annotation on main so code that type-checks against the package keeps
type-checking, and take the Mistral speech and fal.ai Bria changes back out so no
provider error message differs from main

* refactor(types): leave the Vertex RAG chunking read as it is on main

Take the chunking format validation back out of the Vertex RAG ingestion path. It needs the vertexai SDK, a storage bucket and a RAG corpus to execute, so nothing here could run it end to end, and it cleared only two errors

* test(integration): pin the validated provider boundaries on a live proxy

* test(integration): give the held burst a client that outlasts the gate

The fault cell holds a burst at the upstream for up to 60 seconds while it kills a worker, but sent the burst through the shared 15 second client, so a slow box could time the survivors out before the gate opened. The burst now goes through its own client whose timeout is twice the gate, and the gate length is one named constant.

* refactor(types): keep the license reply handling and experimental MCP signatures as they were

The license check validated the whole reply as a mapping, which changed the error text logged for a reply that is not an object. It now validates only the verify value, so every reply is handled and logged exactly as before while the value is still typed.

Three files under the experimental MCP server changed annotations on public functions and methods (three returns and three parameters). They go back to their previous content so no public signature in the diff is narrowed.

* test(integration): answer the proxy's model-list call in the OpenAI stand-ins

Every 300 seconds each proxy worker asks an OpenAI deployment for GET /v1/models. Four new cells own an OpenAI stand-in that accepted only the call under test, so a refresh landing inside a cell failed it. The stand-ins now answer that call through the suite's own helper and the cells count only the provider calls they drive.
