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.

Add a model selector to the chat input area, letting users pick a
model directly from chat instead of going through settings. Adds
i18n translations for the selector across all supported locales.

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.

Signed-off-by: daewoongoh <daeungoh@gmail.com>
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.

Walkthrough

The chat toolbar adds a model selector. It supports static and dynamic providers, organization allowlists, fuzzy search, model updates, unsupported-provider settings fallback, localization, and focused tests.

Changes

Chat model selection

Layer / File(s) Summary
Toolbar integration
webview-ui/src/components/chat/ChatTextArea.tsx
The chat toolbar renders ModelSelector with the active API configuration and organization allowlist.
Model loading and selection
webview-ui/src/components/chat/ModelSelector.tsx
The selector loads static or dynamic models, filters models, supports search, updates provider configuration, and opens settings when selection is unsupported.
Validation and localization
webview-ui/src/components/chat/__tests__/*, webview-ui/src/i18n/locales/*/chat.json
Tests cover provider models, search, allowlists, loading, selection, fallbacks, and Bedrock filtering. All listed chat locales add model-selection strings. The focus-navigation retry limit increases from 10 to 15.

Merge Risk: 🟡 Moderate · up to c754d

Supported providers with no returned or permitted models can be misleadingly sent to Settings rather than receiving an appropriate empty or error state. The new search control also excludes keyboard and assistive-technology users. Resolve these before merging.

Full details: Regression Evidence

Explanation

The new ModelSelector behavior has an uncovered unset-provider path. ModelSelector.tsx explicitly falls back from an unset apiConfiguration.apiProvider to providerIdentifiers.openrouter, and ExtensionStateContext initializes apiConfiguration as {}, so this path is reachable during initial state loading. The focused ModelSelector.spec.tsx tests always provide an explicit provider. Existing ChatTextArea tests may render with incomplete state, but they do not assert this behavior. The PR does include the required Playwright chat-composer snapshots, and the explicit static, dynamic, retired, allowlist, loading, search, and Bedrock cases have focused tests.

Resolution

Add a focused ModelSelector.spec.tsx test with apiConfiguration={{}} and mocked OpenRouter data. Assert that the selector uses the OpenRouter model list and does not show the unsupported fallback. Also cover the selected-model isLoading branch separately from the router-model loading branch, because the component gates the fallback and loading label on both values.

Full details: Persistence Integrity

Explanation

The new persistence path can store a conflicting Bedrock profile. ModelSelector.handleSelect spreads apiConfiguration and changes only modelConfig.field at webview-ui/src/components/chat/ModelSelector.tsx:131-137. The selector removes custom-arn from the list, but it does not clear a previously stored awsCustomArn. If a user has a Bedrock custom-ARN profile and selects the Bedrock default or another listed model, upsertApiConfiguration persists both the new apiModelId and the old ARN. The awaited backend upsert stores that payload. On the consumer path, AwsBedrockHandler uses any awsCustomArn and overrides apiModelId from the ARN, so the persisted model selection is not propagated and the profile becomes semantically inconsistent. The existing settings helper explicitly clears awsCustomArn for this transition, but the changed chat path does not.

Resolution

Before posting the Bedrock model update, clear awsCustomArn when selecting a normal model, or reuse handleModelChangeSideEffects so the same provider-specific cleanup runs. Add a regression test with { apiProvider: bedrock, apiModelId: "custom-arn", awsCustomArn: validArn }, select a listed Bedrock model, and assert that the upsert payload has the new apiModelId and an empty or absent awsCustomArn.

Full details: Lifecycle Resource Cleanup

Explanation

The PR activates an uncancelled request path in chat. ChatTextArea.tsx:1317-1323 mounts ModelSelector, which calls useRouterModels and useSelectedModel at ModelSelector.tsx:60-61. For a dynamic provider, useRouterModels executes fetchRouterModels; that helper adds a window message listener and starts a 10-second timer (useRouterModels.ts:17-55). Its cleanup runs only on a matching response or timeout. It does not consume or handle the React Query cancellation signal. If the chat component is disposed, or the active API configuration changes before the response, the abandoned listener and timer remain active until timeout, and the old extension request continues while the new provider request starts. The same newly activated useSelectedModel path also has equivalent uncancelled message requests for LM Studio and Ollama. The new ModelSelector tests do not cover unmount, provider changes, or cancellation. The two router hook observers are not treated as duplicate work because they share the same React Query key; the failure is the missing cleanup after disposal or restart.

Resolution

Propagate the React Query signal into the request helpers used by the new component. On abort, remove each message listener, clear its timeout, and settle or cancel the request safely. Apply this to fetchRouterModels, the LM Studio and Ollama model requests, and the OpenRouter provider request (pass the signal to Axios). Add tests that unmount or switch providers while each request is pending, then verify that listeners, timers, and stale requests are cleaned up and that a subsequent provider request does not retain the old handler.

Inline comments:
In `@webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx`:
- Around line 283-312: Extend the ModelSelector loading test to simulate the
useRouterModels transition from loading to loaded: update the mock with returned
models, rerender the existing component, and wait deterministically for the
loading label to disappear and the returned model to become selectable. Keep the
test cleanup isolated and verify the selector no longer shows the loading state
after the update.

In `@webview-ui/src/components/chat/ModelSelector.tsx`:
- Line 88: Update ModelSelector’s state logic around isSupported so provider
capability is tracked independently from the filtered modelIds list. Represent
query/loading failure separately, treat an empty allowlist-filtered list as
unavailable without labeling the provider unsupported, and reserve the
unsupported fallback near the rendering branch for providers with no
model-selection capability.
- Around line 241-244: Replace the search-clear span in ModelSelector with a
native named button or existing IconButton using type="button", preserving its
setSearchValue("") behavior and styling. Add and use a localized “Clear search”
translation key in the common catalogs; do not reference the undefined
common:ui.clear key.

Cover the loading-to-loaded transition.

This test stops while useRouterModels is loading. It does not prove that newly returned models update and enable the selector.

Update the mock, rerender the component, and assert that the loading label disappears and the returned models become selectable. This case detects the survived dependency-array mutation at ModelSelector.tsx Line 84.

As per path instructions, tests require “cleanup and deterministic async behavior.”

283 - 312, Extend the ModelSelector loading test to simulate the useRouterModels
transition from loading to loaded: update the mock with returned models,
rerender the existing component, and wait deterministically for the loading
label to disappear and the returned model to become selectable. Keep the test
cleanup isolated and verify the selector no longer shows the loading state after
the update.

Separate provider support from model availability.

isSupported becomes false when the organization allowlist removes every model. Line 188 then labels the supported provider as unsupported and directs the user to Settings, where the same allowlist still applies.

A router-model failure can enter the same branch after loading stops. Track provider capability, query failure, and an empty filtered list as separate states. Use the unsupported fallback only when the provider has no model-selection capability.

ModelSelector’s state logic around isSupported so provider capability is tracked
independently from the filtered modelIds list. Represent query/loading failure
separately, treat an empty allowlist-filtered list as unavailable without
labeling the provider unsupported, and reserve the unsupported fallback near the
rendering branch for providers with no model-selection capability.

Use a native, named button for the search clear control.

When searchValue.length > 0, the span is the only clear action. Its onClick supports pointer input, but the span is not focusable or keyboard-activatable and does not expose a named control to assistive technology. Replace it with a native button or the existing IconButton, using type="button" and a localized accessible name for “Clear search.” Add that translation key to the common catalogs; common:ui.clear is not defined.

Address CodeRabbit review on PR Zoo-Code-Org#1633: an org allowlist that filters out
every model (or a settled router-model query with zero results) was
incorrectly treated the same as a provider with no model-selection
capability, showing the unsupported/Settings fallback instead of a
disabled trigger. isProviderSupported now only reflects whether the
provider is dynamic or backed by a static model list; add test coverage
for the allowlist-empties-everything case and fix the existing
loading-to-loaded test's expectations to match.
