Release v0.5.3
…fix-0.5.3 chore: strip dev suffix for stable release 0.5.3
Override provider parameter to use 'Anthropic' when model starts with 'anthropic/' for optimal performance. Adds debug logging and updates docstring to document this behavior. Closes #116
Add 16 unit tests covering: - Anthropic models auto-selecting Anthropic provider - Anthropic models overriding any specified provider - Non-Anthropic models using specified provider - General LLM configuration (temperature, max_tokens, etc.) - Caching wrapper integration All tests pass (16/16)

Code Review SummaryRan comprehensive code review with pr-review-toolkit:code-reviewer. Issues IdentifiedImportant (addressed):✅ Missing unit tests for provider auto-selection logic - FIXED
Minor (addressed):✅ Docstring clarity - IMPROVED
SummaryAll identified issues have been addressed. The provider auto-selection logic is now fully tested and documented. |
Make docstring more explicit about provider parameter being completely ignored for Anthropic models, addressing code review feedback.
Resolved conflicts in tests/test_core/test_litellm_llm.py by combining: - Provider auto-selection tests (this branch) - Comprehensive caching wrapper tests (develop) Result: 33 tests total (30 passed, 1 skipped, 2 async failures pre-existing from develop)
The merge incorrectly kept version 0.5.3 instead of 0.5.3.dev0. Develop and feature branches should always have .dev suffix. Version suffix stripping should only happen on main branch releases.

Summary
Automatically routes Anthropic models (anthropic/*) to Anthropic's infrastructure for optimal performance by overriding the provider parameter.
Changes
Why
When using Anthropic models through OpenRouter, routing through Anthropic's infrastructure provides better performance than using other providers' proxies.
Testing
Closes #116
