feat: Support OpenRouter presets - #1276
Conversation
📝 WalkthroughWalkthroughOpenRouter model loading now forwards API keys and base URLs, scopes caches by credentials, retrieves authenticated models and presets, and represents presets as synthetic models. Webview flows and tests now preserve and validate preset selections. ChangesOpenRouter model discovery
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds OpenRouter preset discovery and webview integration, but the current head can return incorrect or incomplete model data when custom base URLs are used, and preset metadata behavior is not consistently validated. The PR is not merge-ready until these correctness issues and affected assertions are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

- Around line 610-614: Update the preset expectations in the openrouter model
tests to assert the synthesized contextWindow and fallback description produced
by getOpenRouterModels(), replacing the not.toHaveProperty checks for each
affected preset block while preserving the existing supportsPromptCache
assertion.
In `@src/api/providers/fetchers/modelCache.ts`:
- Line 93: Add OpenRouter’s provider identifier to URL_SCOPED_PROVIDERS so
model-cache entries include the configured base URL. Add coverage verifying
identical OpenRouter key discriminators with distinct base URLs produce separate
cache entries and results.
In `@src/core/webview/webviewMessageHandler.ts`:
- Around line 1101-1113: Resolve openRouterBaseUrl from message.values with the
saved apiConfiguration fallback in the webview message handler. Pass it to both
the OpenRouter flushModels call and the openrouter candidate options, preserving
explicit message values over saved configuration. Add coverage for saved and
unsaved base URLs.
In `@webview-ui/src/components/settings/ModelInfoView.tsx`:
- Around line 60-67: Add focused rendering coverage for the ModelInfoView
context-window condition: verify models whose selectedModelId starts with
“@preset/” do not render the context-window label or token value, while a normal
model with a positive numeric contextWindow still renders it. Keep the test
scoped to this UI behavior and use the existing component test patterns.

573-613: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winAssert the synthesized preset and both description paths.
The test name says it merges public, user, and preset models, but it only checks the public and user entries. Add an assertion for
models["@preset/flash"]. Include an explicit description case as well as the existingnullfallback case.As per coding guidelines, add focused tests for the returned value and cover explicit and unset/default cases.

The implementation in
src/api/providers/fetchers/openrouter.tsLines 153-221 assignsOPENROUTER_PRESET_DEFAULT_CONTEXT_WINDOWto every preset and does not inspectpreset.models. The single-model test references a128000-token model but expects200000. The multi-model test also expects200000while one referenced model already has that value. These tests accept a fixed fallback instead of proving maximum-context derivation.Resolve referenced models and reserve
200000for unresolved presets, or rename the tests to document fixed-default behavior. Replace the threeexpect(true).toBe(true)placeholders with real assertions.As per coding guidelines, assert the value returned by the function instead of using placeholder assertions.
