Roadmap item: P2 Backend - Make LLM model configurable

llm.py hardcodes anthropic/claude-3.5-sonnet. Switching models requires a code change and redeployment, which slows experimentation and makes it impossible to change models at runtime.

What to do

  1. In llm.py (or config.py), read a MODEL environment variable.
  2. Default to anthropic/claude-3.5-sonnet if not set so existing behaviour is preserved.
  3. Pass the resolved model name to the OpenRouter/API call.
  4. Document MODEL in .env.example and in the relevant README section.

Acceptance criteria

  • Setting MODEL=openai/gpt-4o causes llm.py to call that model.
  • Omitting MODEL uses the existing default.
  • .env.example documents the variable.

Resolved -- already implemented in the codebase.

config.py already reads the MODEL env variable: model = os.getenv('MODEL', 'anthropic/claude-3.5-sonnet'). The LLM analyzer and API endpoints use this as the default model, with per-request overrides also supported.

Closing as already resolved.
