Closes: #1502

Description

Adds a ModelSelector to the chat input toolbar so users can pick a model directly from chat instead of going through Settings.

  • New ModelSelector component (webview-ui/src/components/chat/ModelSelector.tsx), mounted in ChatTextArea next to the existing ModeSelector / ApiConfigSelector.
  • Resolves the model list per provider: dynamic providers (e.g. OpenRouter) via useRouterModels, static-model providers via getStaticModelsForProvider.
  • Falls back gracefully for unsupported/retired providers, showing a selectModelUnsupported tooltip that points back to Settings instead of hiding or breaking the control.
  • Uses Fzf for search once the model list is long enough (SEARCH_THRESHOLD).
  • Adds selectModel / selectModelUnsupported i18n strings to chat.json for all supported locales.

Test Procedure

  • Added unit tests in webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx covering supported/unsupported providers, dynamic vs. static model lists, and search behavior.
  • Manual testing: open chat, switch between API configurations using different providers (e.g. OpenRouter, Anthropic), confirm the model dropdown lists the correct models, selecting one updates the active configuration, and providers without inline model listing show the fallback tooltip.

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added a model selector to the chat interface alongside API configuration and approval controls.
    • Supports provider-specific and dynamically available models, searchable lists, display names, loading states, and organization-based filtering.
    • Selecting a model updates the relevant configuration automatically.
    • Providers without in-chat model selection offer a shortcut to open settings.
    • Added localized model-selection labels and messages across supported languages.
  • Tests

    • Added coverage for model selection, filtering, keyboard navigation, loading, and unsupported-provider scenarios.

Walkthrough

The chat input now includes a model selector. It supports static and dynamic provider models, searchable lists, configuration updates, unsupported-provider navigation to settings, tests, and translations for all supported locales.

Changes

Chat model selection

Layer / File(s) Summary
Model resolution and selection
webview-ui/src/components/chat/ModelSelector.tsx
Adds provider model resolution for static and dynamic models, fuzzy search, model selection, configuration updates, loading states, and settings navigation for unsupported providers.
Chat toolbar integration
webview-ui/src/components/chat/ChatTextArea.tsx, webview-ui/src/components/chat/__tests__/ChatTextArea.visual.tsx
Renders ModelSelector after the API configuration selector and passes the active configuration, organization allowlist, translated title, and layout class. The visual test allows additional focus polling iterations.
Selector validation and localization
webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx, webview-ui/src/i18n/locales/*/chat.json
Tests static and dynamic models, display names, loading, search, keyboard activation, allowlist filtering, Bedrock pseudo-model exclusion, configuration updates, and unsupported providers. Adds selectModel and selectModelUnsupported translations across supported locales.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to cdd30

The inline model selector adds in-chat model changes, but its keyboard activation path is not independently covered by the current test. A keyboard-only regression could affect users who select models without a pointer; the implementation is otherwise ready with low residual risk.

Explanation

The changes satisfy issue #1502 by adding an inline model selector, supporting static and dynamic providers, enabling search, handling unsupported providers through Settings fallback, and adding translations for supported locales.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 4 files.

Full details: Regression Evidence

Explanation

No regression-evidence failure found. ModelSelector.spec.tsx has focused Vitest coverage for static and dynamic model sources, selection messages and setting resets, labels, search and no-results behavior, keyboard activation, allowlists, Bedrock custom-arn exclusion, loading, unsupported providers, retired providers, and an allowlist that removes every model. The changed chat toolbar also has Playwright coverage through ChatTextArea.visual.tsx, with updated theme baselines committed for the visible composer. Locale additions are mechanical configuration.

Full details: Trust And Persistence Invariants

Explanation

No explicit trust or persistence invariant failure is introduced. ModelSelector derives selectable IDs from static/router model records and applies filterModels with organizationAllowList before rendering options. Its selection path only posts the selected filtered ID through the existing upsertProviderProfile flow. That flow awaits saveConfig, locked secret storage, state updates, and webview refresh. The new component adds no secret export, dynamic execution, approval action, or unmanaged lifecycle resource; router-model requests use the existing bounded cleanup and timeout behavior.

Inline comments:
In `@webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx`:
- Around line 41-52: Update the Popover mock used by ModelSelector tests so it
tracks open state through onOpenChange and renders PopoverContent only while
open, or replace it with the real Popover implementation. Extend the tests to
verify model options are unavailable before activating model-selector-trigger
and available after the trigger click.
- Around line 78-84: Update the ModelSelector.handleSelect tests to seed
reasoningEffort, modelMaxTokens, and modelMaxThinkingTokens in both
configuration fixtures, then assert in both upsertApiConfiguration save-payload
expectations that these fields are cleared. Keep the existing partial payload
assertions and verify the normalized cleared values explicitly.
- Line 25: Replace the any-based casts in ModelSelector.spec.tsx, including the
useRouterModelsMock fixture, with the resolved router-model data type,
ProviderSettings type, and precise React component prop types. Type the mocked
fixtures and props directly so TypeScript enforces assignability without
changing the test behavior.

In `@webview-ui/src/components/chat/ModelSelector.tsx`:
- Around line 148-156: Replace the clickable model option div in ModelSelector
with a keyboard-accessible button or semantic listbox option, preserving
handleSelect(modelId), selected styling, and focusability; add a test that
selects a model via keyboard activation.
- Line 169: Update the unsupported-provider condition in ModelSelector so it is
rendered only when isSupported is false and useSelectedModel is no longer
loading; while loading, preserve the loading trigger behavior. Add a regression
test covering a dynamic provider with no model IDs during loading.

Filter the chat model selector's model list through the organization
allowlist so it matches ModelPicker in settings, and keep the trigger
visible while a dynamic provider's models are still loading.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Isolate router-model loading in this test.

Line 285 makes useSelectedModelMock load too. This masks the case where useRouterModelsMock is loading while selected-model resolution is complete. Set this mock's isLoading to false, keep the router-model mock loading, and assert that the trigger remains visible. Update ModelSelector to use router-model loading for this fallback condition. Run the narrowest relevant Vitest suite after the change.

As per coding guidelines, “Add focused tests for UI binding and save behavior” and include “true and false/unset cases when defaults could hide omissions.”

The unsupported-provider fallback could flash briefly for a dynamic
provider whose router-models query was still loading but whose
selected-model resolution had already finished. Gate both the fallback
and the loading label on routerModels.isLoading as well.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the keyboard test trigger selection through the keyboard.

fireEvent.keyDown only dispatches a key event in this harness. ModelSelector has no onKeyDown handler, and the following fireEvent.click invokes the selection handler directly. The test therefore passes even if Enter activation regresses. Use a focus-capable or browser-level keyboard harness and assert that Enter or Space alone posts the update.

As per coding guidelines, tests must cover focused UI behavior and save behavior. As per path instructions, regression tests must use behavior-focused assertions.

432 - 433, Update the keyboard-selection test around ModelSelector to use a
focus-capable or browser-level keyboard interaction, removing the direct
fireEvent.click call. Assert that pressing Enter or Space while the option is
focused alone triggers the expected update/save behavior through
behavior-focused assertions.
