* fix(completion): send prompt_cache_retention to OpenAI instead of silently dropping it litellm.completion(), Router.completion() and the proxy's /v1/chat/completions accepted prompt_cache_retention and listed it as a supported OpenAI param, but completion() never handed it to get_optional_params, and the leftover-kwargs paths skip known OpenAI params, so it never reached the request body. Make it a named argument of completion() and acompletion() like prompt_cache_key and pass it on. A unit guard sends every OpenAI body param through completion() and fails when a param added to OPENAI_CHAT_COMPLETION_PARAMS has no case proving it reaches the wire, the same hole store and prompt_cache_key fell into in #33184. Live e2e tests capture the body OpenAI receives for the proxy, the SDK and the Router on both openai/gpt-5.5 and openai/responses/gpt-5.5. * chore(completion): type the param-forwarding unit test and keep the basedpyright count flat Every new completion() kwarg adds one unknown-argument error at each call site that splats an untyped dict into it; typing print_verbose's argument and Chat's params removes more than prompt_cache_retention added. * test: freeze the outbound-body model and read captured requests from the mock Addresses review: the e2e body model is frozen, the backend params are a tuple, and the unit test reads the request from the respx route instead of appending to a list. |

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.
