* 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 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
