Summary

Currently llm.py uses a single hardcoded model (anthropic/claude-3.5-sonnet via OpenRouter). This issue adds the ability for users to select from multiple LLM providers per analysis run and compare outputs.

What to do

  • Extend the analysis request schema to accept an optional model field (e.g., gpt-4o, gemini-1.5-pro, anthropic/claude-3.5-sonnet).
  • Update llm.py to route to the specified model via OpenRouter (which already supports multiple providers).
  • Store the model used alongside each analysis result in the database.
  • Expose a GET /models endpoint that returns the list of supported/available models.
  • Update the frontend Analysis page to show a model selector dropdown.
  • Document the MODEL default and the per-request override in the README.

Acceptance criteria

  • Analysis requests can specify a model field; the default falls back to the MODEL env var (see issue #763).
  • The selected model is stored in the analysis result and shown in the dashboard.
  • GET /models returns a list of at least three supported models.
  • Existing tests updated to cover the model selection path.

Depends on leeworks-agents/SPARC#763 (configurable MODEL env var).

## Summary Currently `llm.py` uses a single hardcoded model (`anthropic/claude-3.5-sonnet` via OpenRouter). This issue adds the ability for users to select from multiple LLM providers per analysis run and compare outputs. ## What to do - Extend the analysis request schema to accept an optional `model` field (e.g., `gpt-4o`, `gemini-1.5-pro`, `anthropic/claude-3.5-sonnet`). - Update `llm.py` to route to the specified model via OpenRouter (which already supports multiple providers). - Store the `model` used alongside each analysis result in the database. - Expose a `GET /models` endpoint that returns the list of supported/available models. - Update the frontend Analysis page to show a model selector dropdown. - Document the `MODEL` default and the per-request override in the README. ## Acceptance criteria - [ ] Analysis requests can specify a `model` field; the default falls back to the `MODEL` env var (see issue #763). - [ ] The selected model is stored in the analysis result and shown in the dashboard. - [ ] `GET /models` returns a list of at least three supported models. - [ ] Existing tests updated to cover the model selection path. ## Reference Roadmap P3: Multi-model support.

Already Resolved

Multi-model support is implemented: per-analysis model selection is wired through API request models (CompanyAnalysisRequest.model, BatchAnalysisRequest.model), frontend model picker exists, and llm.py uses config.model as default.

Closing as complete.
