Summary

  • persist live-discovered API-key custom models into provider configuration when enabled
  • honor saved model visibility when reloading a custom provider live catalog
  • project legacy enabled custom-model refs into the main picker without mutating configuration during reads
  • add regressions for catalog reload, runtime registry persistence, and legacy picker projection

Testing

  • make lint
  • go test ./... -count=1
  • go test -race ./internal/web -run custom-model regression set -count=1
  • repository pre-push checks (build, vet, lint, tests)

Summary by CodeRabbit

  • New Features

    • Custom-provider models now appear in the model catalog with text and tool-use capabilities.
    • Newly enabled custom models are saved across sessions and become available immediately.
    • Live provider catalogs now reflect each model’s saved enabled or disabled state.
  • Bug Fixes

    • Improved model visibility and configuration consistency for custom API-key providers.
    • Removed models no longer provided by a configured provider from the catalog.

📝 Walkthrough

Walkthrough

Custom-provider catalogs now preserve persisted enablement, expose enabled legacy models, persist newly enabled custom models, and rebuild dependents after configuration changes. Tests cover catalog visibility, persistence, registry registration, removal handling, and API capability projection.

Changes

Custom model management

Layer / File(s) Summary
Persisted custom model catalog visibility
internal/web/providers.go, internal/web/models.go, internal/web/models_test.go
Live and legacy custom-provider models use persisted enablement. /api/models exposes enabled custom models with text and tool-call metadata. Provider updates remove models absent from the current catalog.
Custom model enablement and persistence
internal/web/models.go, internal/web/models_test.go
Eligible custom API-key models persist missing runtime metadata when enabled. Provider dependents rebuild after managed or custom configuration changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 2f5ff

Disabling a previously saved live custom model can leave it appearing as enabled in the provider catalog, which may show the wrong models to users after reload. The PR should address this behavior or obtain explicit owner acceptance before merging.

Summary

The change correctly persists custom live-model enables into config.CustomModels and projects legacy model_state-only refs into /api/models; locking follows the established cfgMu+MutateConfig pattern and no security or data-loss issue was found. Build, vet, and the full internal/web (plus config/model) test suites pass, including the three new tests. One regression: the new projection loop makes EnabledModels refs an independent source of picker truth, so a custom model removed through the provider editor reappears as enabled because removal never prunes model-state refs.
