The model Azure Model Router served was recovered by checking whether the text
"model_router" or "model-router" appeared in a model string. Spend logs applied that
check to the litellm model path, where the route prefix guarantees a match, but the
proxy applied it to the client's model group alias, which carries no prefix. A model
group named anything else therefore lost the selected model in both the response and
the spend row.
AzureModelRouterConfig now stamps the served model onto _hidden_params, and the spend
log payload and the proxy's response restamping read that stamp. The name heuristic
survives as a fallback for callers with no response in hand, routed through
get_azure_ai_route so it lives in one place.
A reasoning item id is not an Anthropic signature. Passing it off as one got the
block replayed to Anthropic and Bedrock as if it were real, and every backend that
verifies signatures rejected the turn. Thinking blocks now come back unsigned, and
the streaming path no longer emits a signature_delta for them.
Azure AI Foundry, Fireworks, and vLLM reject unknown message fields, so they now
strip reasoning_content alongside thinking_blocks the way Mistral already did.
The thinking-block helpers take ChatCompletionThinkingBlock and
ChatCompletionRedactedThinkingBlock instead of loose mappings.
* 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
* fix(azure_ai): strip tool-level extra fields (e.g. copilot_mcp_server_name) before retrying
* fix(azure_ai): move re import to top-level; fix regex to handle hyphenated field names
- Azure Model Router transform_response: let parent extract actual model from raw response
- common_request_processing: skip model override for Azure Model Router requests
- proxy_server: skip streaming chunk model restamp for Azure Model Router
- Add _is_azure_model_router_request helper
- Add tests for non-streaming and streaming
Made-with: Cursor
* fix: _should_use_api_key_header
