Summary

llm.py hardcodes anthropic/claude-3.5-sonnet as the model. Switching models requires a code change and redeploy.

Work to do

  • Add a MODEL environment variable to config.py with anthropic/claude-3.5-sonnet as the default.
  • Update llm.py to read the model name from config.
  • Document the variable in .env.example.

Acceptance criteria

  • Setting MODEL=openai/gpt-4o causes the LLM client to use that model.
  • When MODEL is unset the existing default is used unchanged.
  • No hardcoded model strings remain in llm.py.

## Summary `llm.py` hardcodes `anthropic/claude-3.5-sonnet` as the model.

Already resolved. config.py line 43: model = os.getenv("MODEL", "anthropic/claude-3.5-sonnet"). llm.py reads self.model = config.model. Documented in .env.example. Closing.
