Background

Roadmap reference: ROADMAP.md > P3 > Multi-model support

Currently all analyses use the single model configured via the MODEL env var. Allowing per-request model selection enables A/B comparison of LLM outputs and lets users choose cost vs. quality trade-offs.

What to do

  1. Add an optional model field to the analysis request body (e.g., POST /analyze payload).
  2. If model is provided, use it for this request; otherwise fall back to the MODEL env var default.
  3. Validate that the provided model is in an allowlist (configurable via ALLOWED_MODELS env var) to prevent abuse.
  4. Store the model used in the analysis result record so it is visible in the dashboard.
  5. (Optional) Add a GET /models endpoint returning the list of allowed models.

Acceptance criteria

  • A request specifying model: openai/gpt-4o uses GPT-4o for that analysis.
  • An unrecognised model returns a 400 Bad Request with a helpful message.
  • The model used is visible in the analysis result on the dashboard.
## Background Roadmap reference: ROADMAP.md > P3 > Multi-model support Currently all analyses use the single model configured via the `MODEL` env var. Allowing per-request model selection enables A/B comparison of LLM outputs and lets users choose cost vs. quality trade-offs. ## What to do 1. Add an optional `model` field to the analysis request body (e.g., `POST /analyze` payload). 2. If `model` is provided, use it for this request; otherwise fall back to the `MODEL` env var default. 3. Validate that the provided model is in an allowlist (configurable via `ALLOWED_MODELS` env var) to prevent abuse. 4. Store the model used in the analysis result record so it is visible in the dashboard. 5. (Optional) Add a `GET /models` endpoint returning the list of allowed models. ## Acceptance criteria - A request specifying `model: openai/gpt-4o` uses GPT-4o for that analysis. - An unrecognised model returns a `400 Bad Request` with a helpful message. - The model used is visible in the analysis result on the dashboard.

Closing: already implemented in main. Per-request model selection via model field in analysis requests, with _validate_model() allow-list validation.
