Cesar GarciaandGitHub 5e70c78b94 fix(cost-tracking): support base_model lookup in litellm_metadata for Responses API (#16778)
Cost tracking was failing for Responses API when using custom deployment names
with base_model configuration. The issue occurred because:

- Chat Completions API stores model_info in 'metadata'
- Responses API stores model_info in 'litellm_metadata'
- Cost calculator only checked 'metadata', missing Responses API costs

Changes:
- Updated _get_base_model_from_metadata() to check both metadata locations
- Added comprehensive unit tests covering all scenarios
- Maintains backward compatibility (metadata takes precedence)

Fixes #16772

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.
