The _resolve_model_for_cost_lookup function was only checking litellm_params.model when resolving model names from the router. For Azure custom deployment names (e.g. azure/openai/gpt-5.3-codex), this deployment name doesn't exist in the model cost map, so cost returned /bin/zsh. Now checks model_info.base_model and litellm_params.base_model first, falling back to litellm_params.model only if no base_model is set. This matches how the router resolves base_model everywhere else.
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/test_litellm
This folder can only run mock tests.
