The model-list builders are sync, and with check_provider_endpoint on they call OpenRouter's catalog with a 10 second timeout and no caching of failures. They ran on the event loop inside /v1/models, /model/info, /model_group/info and the per-user listing, so one slow catalog froze every request on the worker. Those calls now run in a worker thread with asyncio.to_thread File, batch and RAG credential lookups only need each name's deployment, and a wildcard that is itself a deployment sits in the list ahead of its expansions and resolves its own credentials. get_complete_model_list takes expand_deployed_wildcard_routes, which that lookup sets to False, so a deployed wildcard never fetches its provider catalog there. A key wildcard wider than any deployment, like anthropic/* over a deployed anthropic/claude-*, still expands so it finds the matching deployment's credentials. Every other caller keeps the default The pattern router's model lookup tolerates a pattern removed between its two reads of the pattern table, which a deployment delete on the event loop can now do while a listing runs in a thread Listing now reads only OpenRouter's models/user catalog. OpenRouter's own /models list carries no embedding models, the OpenAI-format /v1/models has no mode field so chat pickers cannot tell embeddings apart, /model_group/info labels them mode chat, and one failing catalog emptied the whole list. Ids ending in :batch are dropped because chat completions answers 404 for them, while :free and every other variant stay. An api_base that already ends in /chat/completions, which chat accepts as is, has that suffix stripped before the catalog route is joined |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/unit
This folder can only run mock tests.
