Summary

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

Work

  • Add a MODEL environment variable (default: anthropic/claude-3.5-sonnet).
  • Read the value in config.py and pass it through to llm.py.
  • Remove the hardcoded string from llm.py.
  • Document the variable in .env.example.

Acceptance Criteria

  • Setting MODEL=openai/gpt-4o causes that model to be used for analysis without code changes.
  • Unsetting MODEL falls back to the current default.
  • .env.example documents the variable with the default value.

## Summary `llm.py` hardcodes `anthropic/claude-3.5-sonnet` as the model. Switching models requires a code change and redeploy. ## Work - Add a `MODEL` environment variable (default: `anthropic/claude-3.5-sonnet`). - Read the value in `config.py` and pass it through to `llm.py`. - Remove the hardcoded string from `llm.py`. - Document the variable in `.env.example`. ## Acceptance Criteria - Setting `MODEL=openai/gpt-4o` causes that model to be used for analysis without code changes. - Unsetting `MODEL` falls back to the current default. - `.env.example` documents the variable with the default value.

Triage (AI-Manager): P2, small complexity. Assigned to @AI-Engineer (developer role). Straightforward backend configuration/type fix. Second sprint priority after P1 issues are resolved.

Triage (Repo Manager): Delegating to @developer. This is a P2 small-scope task with clear acceptance criteria. Straightforward implementation.
