feat(friendli): fetch models from /v1/models - #2331
Friendli models now come from the public https://api.friendli.ai/serverless/v1/models endpoint. This endpoint does not need an API key. The fixed friendliModels list stays as a fallback.
src/api/providers/fetchers/friendli.ts: A new fetcher gets the catalog and keeps only chat models. It maps the context window, max output, prices, cache read price, image input, and reasoning effort values.
FriendliHandler: The handler does not fetch the catalog at construction. It loads the catalog one time, before its first request, through getModels. If the request fails or returns no entry, the handler uses the fixed list or the default model info. The handler keeps a configured model ID that is not in the fixed list. The handler does not need an API key at construction, because the catalog is public.
Friendli is now a dynamic provider. requestRouterModels always fetches its catalog.
Webview: The model picker and useSelectedModel use the fetched models when they are available. Before the data loads, they use the fixed list.
Reviewers must check this behavior change: a request with no API key now goes to Friendli and fails with HTTP 401. Before, the handler failed at construction. Kimi Code works the same way.
Test Procedure
Unit tests:
cd src && npx vitest run api/providers/__tests__/friendli.spec.ts api/providers/fetchers/__tests__/friendli.spec.ts core/webview/__tests__/webviewMessageHandler.spec.ts core/webview/__tests__/ClineProvider.spec.ts
cd webview-ui && npx vitest run src/components/ui/hooks/__tests__/useSelectedModel.spec.ts src/components/settings/utils/__tests__/providerModelConfig.spec.ts
pnpm check-types
The tests cover these cases:
Construction with no API key does not fail and does not fetch the catalog.
The fetcher calls the public URL and forwards the abort signal.
The handler loads the catalog one time, and waits for it before it streams.
An empty catalog falls back to the fixed list.
An unknown model ID keeps its ID when the catalog request fails.
The webview uses the fixed list before the router models load.
Manual check:
Run curl -s https://api.friendli.ai/serverless/v1/models. The response has a data list.
Select the Friendli provider in Zoo Code settings.
Open the model picker. It shows the models from the response.

Summary
Summary by CodeRabbit
New Features
Friendli can discover available models and their capabilities, context limits, pricing, and other details from its public catalog without credentials.
Discovered models appear in settings and provide model information for selection.
Friendli remains usable with its static model information while the catalog loads or if catalog details are unavailable.
Friendli is available as a dynamic provider, and configured model selections are preserved.
Friendli is added to dynamic model handling. The system fetches and maps its public model catalog, includes Friendli models in router results, and uses fetched metadata in provider and webview model selection with static fallbacks.
Changes: Friendli model catalog

Summary
Recognize Friendli and map its catalog packages/types/src/provider-settings.ts, packages/types/src/__tests__/provider-identifiers.test.ts, src/api/providers/fetchers/friendli.ts, src/api/providers/fetchers/__tests__/friendli.spec.ts
Friendli is added to the dynamic provider list. The fetcher validates catalog responses and maps chat model metadata, including limits, capabilities, prices, reasoning options, and descriptions. Tests cover mapping and failure cases.
FriendliHandler caches fetched models and exposes catalog fetching. Model lookup uses fetched metadata, then static metadata, then OpenAI sane defaults. Router model results include Friendli.
Use fetched Friendli metadata in model selection webview-ui/src/components/settings/utils/providerModelConfig.ts, webview-ui/src/components/settings/utils/__tests__/providerModelConfig.spec.ts, webview-ui/src/components/settings/ApiOptions.tsx, webview-ui/src/components/ui/hooks/useSelectedModel.ts, webview-ui/src/components/ui/hooks/__tests__/useSelectedModel.spec.ts, webview-ui/src/components/settings/providers/__tests__/*, webview-ui/src/utils/__tests__/validate.spec.ts
The settings picker and selected-model hook use fetched Friendli metadata when available and fall back to the static catalog. Related fixtures and tests include Friendli router data.

Explanation
[#2332] The public catalog fetcher maps chat models, token limits, pricing and supported reasoning-effort values. The picker uses fetched models and falls back to the fixed list. The handler and automated tests cover loading and fallback. The prior assessment required budget_tokens mapping, but the issue requires reasoning-effort values, not token budgets.

The changed catalog fetch uses a fixed public URL and validates the response. The model picker retains organization allowlist filtering. No changed path shows a concrete secret leak, unsafe execution, or control bypass.
Full details: Persistence Integrity
Explanation
The changed Friendli catalog path uses the existing model cache. The cache awaits its file write and uses safeWriteJson for replacement and rollback. The changed selection code preserves configured model IDs.
Full details: Regression Evidence
Explanation
Two changed paths lack focused regression coverage: - ApiOptions.tsx:776-781 passes the fetched catalog to the picker. The new utility and hook tests do not verify this wiring. The Friendli component tests check only the provider form. - friendli.ts:213-214 adds cancellation during catalog loading to completePrompt. The cancellation test covers only createMessage; the completePrompt test checks signal forwarding after loading. The previous failure is addressed: the fetcher test checks cancellation, and the picker utility test checks an empty Friendli catalog.
Resolution
Add a component test that verifies fetched Friendli models reach the picker. Add a completePrompt test that cancels a pending catalog load and asserts rejection without a chat request.
Full details: Lifecycle Resource Cleanup
Explanation
The catalog wait still has a cancellation race. In src/api/providers/friendli.ts:96-97, cancellation can occur after settleOnAbort resolves but before the generator resumes. The generator then starts a chat without checking the signal. The base provider does not pass the signal to createStream, so a restarted task can overlap with that stale request. The new test covers cancellation while the catalog remains pending, not this race. The prior failure is only partly addressed: streaming cancellation is still not forwarded.
Resolution
Check the abort signal after the catalog wait and before starting the chat. Forward the signal to the streaming request while preserving shared catalog loading. Add tests for cancellation at catalog settlement and during streaming.

Current step: Address maintainer or CODEOWNER feedback, push an update, then re-request review from the blocking maintainer.
Review-state labels are managed by this workflow; do not edit them manually. community-approved is managed the same way — do not add or remove it manually. It signals a fresh community code approval for the current head as an advisory priority only; maintainer review is still required.
Add or strengthen a focused test that fails under the mutation. If the mutant is equivalent, request maintainer approval for the narrowest mutator-specific exclusion and explain why it cannot change behavior:
// Stryker disable next-line ConditionalExpression: normalized input cannot reach the alternate branch
const result = condition ? value : fallback
Broad all exclusions and exclusions without a concrete reason are reported as advisories.

metadata when query data is unavailable, including before any data is cached.
Keep fetched query data as the source once it becomes available.
Review comments at @src/api/providers/friendli.ts:
- Around line 90-92: Update the Friendli request-construction flow around
getModel so it waits for the Friendli model catalog fetch to complete before
resolving metadata for the selected model. Preserve the existing fallback
behavior when the fetch fails, and ensure request construction uses the resolved
metadata for fetched-only models.
- Around line 81-83: Remove the eager getModels request from handler
construction and defer catalog fetching until Friendli model metadata is needed.
Reuse the existing friendliModels fallback, and ensure handler construction
alone does not trigger repeated background requests when the cache is empty.

84-89: Prevent a failed or empty catalog fetch from being retried per handler construction.
modelsLoad is memoized per handler instance. A new handler repeats the fetch when the cache is empty. The fetch now starts lazily in createMessage and completePrompt, not in the constructor. This addresses the earlier construction-time concern. No further action is needed.

Retry an empty or failed catalog on the next request.
If the first catalog load returns {} or rejects, modelsLoad remains settled. Later requests on the same handler never retry, so a fetched-only model keeps fallback metadata after the catalog recovers. Clear the settled promise on empty results and failures while retaining the shared in-flight promise. BaseProvider.ensureCatalogLoaded already implements that retry pattern.
