Model Selection

OpenChat separates model selection from provider credential management, so users can switch quickly without leaving chat.

Model Selector UX

Implemented in model-selector.tsx with desktop and mobile variants:
  • Search by model/provider.
  • Filter by provider/favorites.
  • Hover/info panel for model metadata.
  • Keyboard navigation for accessibility.

Favorite Models

  • Stored in local persistent state.
  • Used for fast grouping in retry/fork model menus.
  • Defaults can be seeded in selector UI.

Provider Modes

  • osschat provider for shared hosted usage profile.
  • BYOC/BYOK providers configured in Settings > Providers.
  • Active provider and daily usage/search state in provider.ts.

Reasoning Controls

  • Reasoning toggle appears only for capable models.
  • Effort levels are tracked in model state and sent at generation time.

Model Catalog Source

  • GET /api/models proxies the OpenRouter models endpoint.
  • Uses Upstash-backed cache and IP-based rate limiting.
  • Includes TRUST_PROXY safeguards for rate-limit identity correctness.
