Closes: #1502

Description

Adds a searchable chat model selector to the chat input bar so users can switch the model for the active API profile without leaving the chat.

New ChatModelSelector popover, mounted in ChatTextArea next to the API config selector.
New useChatModelSelector hook resolves the provider's model list (static per-provider defaults, router catalog for OpenRouter/Requesty/etc., and custom models), filters deprecated models (keeping the currently selected one), supports search, and picks the matching modelIdKey for storage.
Handles compound provider values (e.g. VS Code LM) with value/display transforms.
Selecting a model posts upsertApiConfiguration for the active profile; the backend persists it, activates it, and broadcasts the updated apiConfiguration back to the webview.
Adds chat.* i18n keys across all 18 locales and a Playwright visual snapshot for the dark sidebar chat.

Behavioral guarantees:

Trigger reflects the persisted selection, never the transient search text.
No silent model switches: selection is a no-op when the profile name is unset or the model is disallowed by the organization allowlist.
Organization allowlist enforced at both layers: the model list is filtered in the webview, the custom-model entry point is hidden for restricted providers, and every profile write is validated in the extension host before it is persisted.
Correlated model discovery: message-based model requests carry a requestId and only the matching response is applied, so a late response cannot repopulate a switched-away provider. OpenAI-compatible providers leave the loading state on empty or failed responses.
Transactional profile update: a failed activation restores the previous provider settings, active profile name, and mode binding.

Test Procedure

cd webview-ui && npx vitest run src/components/chat/__tests__/ChatModelSelector.spec.tsx src/components/chat/hooks/__tests__/useChatModelSelector.spec.tsx
cd src && npx vitest run core/webview/__tests__/webviewMessageHandler.spec.ts core/webview/__tests__/ClineProvider.apiHandlerRebuild.spec.ts

Results: 47 passed, 84 passed, 16 passed, 205 passed. ESLint and tsc --noEmit are clean for the changed files and both packages.

📝 Summary

Summary by CodeRabbit

New Features
- Added a model selector beside the API configuration selector in chat, showing models available for the active provider.
- Selected models are saved to the active configuration profile when available.
- Added support for selecting VS Code language models by vendor and family.
- The selector is disabled when the active profile or required model configuration is unavailable. Custom model options are hidden when provider policy restricts them.

The chat input now includes a provider-aware model selector. It resolves model options for supported providers, displays them through compact ModelPicker mode, and saves selections to the active API configuration profile.

Changes: Chat model selection

Layer / File(s)	Summary
Resolve provider model data `webview-ui/src/components/chat/hooks/useChatModelSelector.ts`, `webview-ui/src/components/ui/hooks/useVsCodeLmModels.ts`	The hook resolves provider model lists, defaults, configuration keys, loading states, and provider-specific value transforms. The VS Code LM hook requests models through the webview message channel and returns an empty list when the response omits them.
Add compact ModelPicker mode `webview-ui/src/components/settings/ModelPicker.tsx`	`ModelPicker` supports compact triggers, configurable popover placement, disabled and loading states, provider overrides, and custom-model suppression. The settings mode retains its initialization behavior and uses shared popover content.
Wire model selection into chat `webview-ui/src/components/chat/ChatModelSelector.tsx`, `webview-ui/src/components/chat/ChatTextArea.tsx`, `webview-ui/src/components/chat/__tests__/*`	`ChatTextArea` renders `ChatModelSelector`. The selector applies provider model data and organization policy, then posts a selected model to the active profile when the required profile data is available. Tests cover displayed labels, persistence, missing profile data, restricted model options, and the composer focus loop.

Merge Risk: 🟡 Moderate · up to c5bda

For restricted VS Code LM profiles, selecting a displayed model can disable chat, and switching providers can leave the model list empty. These risks are bounded to the new selector but warrant correction before relying on it.

Full details: Regression Evidence

Explanation

New model-discovery error behavior lacks focused coverage. useVsCodeLmModels adds a 10-second timeout that rejects and removes its message listener, and it has a disabled path that must not post a request (webview-ui/src/components/ui/hooks/useVsCodeLmModels.ts:8-37). No useVsCodeLmModels test exists at the PR head. ChatModelSelector.spec.tsx mocks this hook, so it cannot detect regressions in the timeout, listener cleanup, disabled request suppression, unrelated-message handling, or missing-response fallback.

Resolution

Add a focused useVsCodeLmModels hook test. Verify that enabled: false does not post a request, a matching response resolves and removes the listener, unrelated responses do not resolve the request, an absent model array resolves to [], and the 10-second timeout rejects and removes the listener. Use fake timers and assert the message listener cleanup. Also add focused useChatModelSelector coverage for its provider-routing and retired/unset branches, because the reported hook test path is absent from the PR.

Full details: Persistence Integrity

Explanation

The new chat selection path posts upsertApiConfiguration from ChatModelSelector.tsx:39-49. The handler awaits upsertProviderProfile, but that method saves the profile at ClineProvider.ts:1887 before separate Promise.all writes for global state, mode binding, and context at 1904-1909. Its catch at 1924-1930 only logs and reports an error. If a later write fails, the model profile remains saved while activation state can remain old. The new chat path therefore activates a non-atomic persistence operation without rollback or explicit partial-failure handling. A second loss case exists for an unset provider: useChatModelSelector.ts defaults to OpenRouter and writes openRouterModelId, while ProviderSettingsManager.saveConfig parses provider-less profiles with the default schema (packages/types/src/provider-settings.ts:215-238,261-263), which strips provider-specific fields. The selected model is then lost on reload.

Resolution

Make profile model selection transactional. Persist the profile, active-profile state, mode binding, context settings, and task state in one atomic operation, or snapshot and restore every prior value when any activation step fails. Report partial failure separately instead of returning after only logging. Also disable model persistence when apiProvider is unset, or persist the matching provider together with the provider-specific model field so schema validation does not strip the selection.

Full details: Lifecycle Resource Cleanup

Explanation

The new useVsCodeLmModels path can retain resources after disposal. getVsCodeLmModels adds a window message listener and a 10-second timer, but cleanup runs only after a matching response or timeout (lines 10-17 and 29-30). The React Query wrapper does not pass or handle an abort signal (lines 33-37). If the chat selector unmounts or switches away from VS Code LM while the request is pending, the listener and timer remain active, and a late response can still resolve the abandoned request.

Resolution

Make getVsCodeLmModels accept an AbortSignal or an explicit cancellation callback. Remove the message listener and clear the timeout in the abort/unmount path, and guard resolution after cleanup. Pass React Query's signal from queryFn to the request. Use a provider/request-specific query key or request correlation if a late response could be observed after the provider changes.

Review comments at
@webview-ui/src/components/chat/__tests__/ChatModelSelector.spec.tsx:
- Around line 113-119: Update the fixture used by the “renders the trigger with
the current model id” test so defaultModelId is the Sonnet ID while the active
model remains the Opus ID. Keep the trigger assertion checking the Opus ID to
ensure it verifies the normal selectedModelId display path rather than the
default fallback.

Review comments at @webview-ui/src/components/chat/ChatModelSelector.tsx:
- Around line 45-51: Update the displayValue calculation in ChatModelSelector so
it depends only on the configured or selected model, not searchValue. Remove
searchValue from the fallback and dependency list, preserving the existing
displayTransform behavior so typing a query does not change the trigger label or
selected-row highlight.
- Around line 74-81: Update ChatModelSelector so the model-selection trigger is
disabled when currentApiConfigName is missing, and make onSelect return early in
that case before posting the upsertApiConfiguration message.

Review comments at
@webview-ui/src/components/chat/hooks/useChatModelSelector.ts:
- Around line 345-350: Update the OpenAI model loading logic in the
useChatModelSelector hook to track whether an OpenAI models response has arrived
separately from the model list length. Mark the response received when handling
openAiModels, use that state in the isLoading calculation so an empty or failed
response ends loading, and reset it when the provider changes or a new request
is posted.
- Around line 155-221: Correlate message-based model responses with the request
that produced them so late responses cannot repopulate state after a provider
switch. Update the shared message contract to carry a correlation ID on each
model request and response, have the request effect in the hook generate and
track the current ID, and make its onMessage listener apply results only when
the response ID matches. Update the corresponding extension handlers to
propagate the ID from each request into its response.

181-186: 💤 Low value

The provider-switch reset can discard a model response that arrives after the request.

Line 186 depends on activeProvider, and React runs effects in declaration order. On mount and on each provider switch, the reset effect at Lines 181-186 runs before the request effect at Lines 192-221. The reset does not run again later, so a response that arrives after the request survives. Two cases still lose data:

A response from the old provider can arrive after the switch. That response is then stored in the new provider's slot. The hook writes all four lists from any message, so this only matters when switching between two message-based providers that share a list. That is rare.

Settings-page components post the same requestOllamaModels messages. Responses to those requests also update this hook, which is harmless.

This concern is minor. One fix lowers the race risk: store only the message types that match activeProvider. To do that, read the current provider through a ref inside onMessage.

webview-ui/src/components/chat/ChatModelSelector.tsx (1)

177-203: The empty-state message is missing when the search matches no models and the search box is empty.

modelListEmpty renders only when modelIds.length === 0. When a search matches no models, filteredModelIds is empty and the custom-model option appears, which is acceptable. When isLoading is true and the list is empty, nothing renders below the search box. Combined with the permanent loading state on Lines 345-350 of useChatModelSelector.ts, the popover stays blank.

Fix the root cause in the hook, as described in that comment.

Pre-merge checks failed. Please resolve the failing checks before merging.

Inline: trigger label no longer follows search text; disable + early-return when currentApiConfigName is unset; correlate message-based model responses with requestId; stop OpenAI-compatible permanent loading on empty/failed response. Security boundaries: validate selections against organizationAllowList in the webview and enforce ProfileValidator at the upsertApiConfiguration/saveApiConfiguration persistence boundary. Persistence integrity: snapshot and roll back provider settings, current profile name, and mode binding when upsertProviderProfile fails after mutation. Side effects: webviewMessageHandler now reads organizationAllowList via provider.getState() before profile writes; ClineProvider.upsertProviderProfile now calls getModeConfigId before activation and setModeConfig on rollback. Tests: ChatModelSelector/useChatModelSelector (47), webviewMessageHandler (84), ClineProvider.apiHandlerRebuild (16) and ClineProvider.spec (205) all pass; eslint + tsc clean. Sync: based on main 09e7326 (upstream/main).

174-181: Clear the Ollama, LM Studio, and VS Code LM lists when the request effect reruns.

The changed effect clears only the OpenAI list. For other message-based providers, the effect reruns only when activeProvider changes. The provider-change effect at Lines 156-163 already clears those lists in that case. No concrete stale-state defect is visible for them.

The OpenAI-specific reset at Lines 178-181 is consistent with the response-ID correlation in onMessage (Lines 133-139). The reset runs before latestRequestId.current is reassigned. A late response for the previous request is rejected by isStale(), because the new ID replaces it. Cleanup also sets the ID to undefined, so late responses are dropped.

One edge remains. A response with no requestId is accepted at Line 133. If the backend ever sends a broadcast openAiModels message without an ID, it can repopulate the list after the reset. This path is permitted by design, as the comment at Lines 131-132 says. No change is required.

Preserve version in the VS Code LM allowlist key.

Restricted model lists require exact model-ID matches. ProfileValidator currently reduces a selector with version to vendor/family, so a persisted versioned selector can pass a family-only entry. VsCodeLmHandler passes the selector to vscode.lm.selectChatModels and identifies a client without id as vendor/family/version.

The normal selectors preserve family-only behavior, so include version only when it is present. Add both allow and deny assertions for versioned selectors.

🐛 Suggested fix

- (selector?.vendor && selector?.family ? `${selector.vendor}/${selector.family}` : undefined) + (selector?.vendor && selector?.family + ? `${selector.vendor}/${selector.family}${selector.version ? `/${selector.version}` : ""}` + : undefined)

🟡 Minor · Preserve a newer launch name during compensation. · ClineProvider.ts:1984-1990

src/core/webview/ClineProvider.ts:1984-1990
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Preserve a newer launch name during compensation.

When webviewDidLaunch finds a stale name, it writes the fallback name before queuing activateProviderProfile. If the earlier chat upsert fails, the compensation at this line restores previousName after that fallback write. If the queued activation then rejects during activateProfile, no later state write or broadcast restores the fallback, so the persisted name and webview state remain stale.

Restore previousName only when the current name still belongs to this upsert:
Suggested fix
-							await restore(() => this.updateGlobalState("currentApiConfigName", previousName))
+							if (this.contextProxy.getValue("currentApiConfigName") === name) {
+								await restore(() => this.updateGlobalState("currentApiConfigName", previousName))
+							}

420-423: Each successful save records the stale closure value of apiConfiguration.

postApiConfiguration pushes the apiConfiguration value from the current render. This is the same value that it posts, so the baseline matches the submitted payload. The backend merge can still keep concurrent edits that the webview never received. After a success, Line 168 sets the baseline to the submitted configuration and not to the merged result that the backend stored. The next save then diffs against a baseline that lacks those concurrent fields. A field that another writer changed and this view left untouched compares as equal, so the merge skips it. This keeps the other writer's value. The behavior is safe, and no change is needed.

330-353: Verify the disabled compact trigger still works with PopoverTrigger asChild.

The disabled prop on PopoverTrigger passes to the child button. The caller's button already sets disabled. This path is consistent. No defect found.

39-52: Selections write a stale full apiConfiguration snapshot to the profile.

persistModel upserts { ...apiConfiguration, [modelIdKey]: value }. The webview apiConfiguration is the active runtime config. If the user has unsaved edits in the Settings view, or the extension state lags, this upsert overwrites the profile with the older snapshot plus the new model. This is limited to the same-profile state the webview already holds, so the risk is low. The PR states the backend persists the full config. No change is required.

webview-ui/src/components/chat/__tests__/ChatModelSelector.spec.tsx (1)

110-110: Ignore the secret-scanner hit.

Line 110 holds a model ID (claude-3-opus-20240229), not an API key. The hit is a false positive. No change is needed.

Add coverage for the VS Code LM selection payload.

This test checks that the option is listed. It does not select it. The valueTransform path stores { vendor, family }. No test asserts this payload. A regression in the split logic would pass.

Select the option, then assert apiConfiguration.vsCodeLmModelSelector equals { vendor: "copilot", family: "gpt-4o" }.

TanStack Query v5 official docs query key query function changes staleTime default refetch on option change

💡 Result:

Here’s the v5 behavior in brief: - **Query keys and query functions:** v5 uses the object form, e.g. `useQuery({ queryKey, queryFn })`. Include in `queryKey` any variable your query function depends on. When the key changes, it selects a separate cache entry and can fetch for it; whether it fetches depends on `enabled` and freshness. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/migrating-to-v5?utm_source=openai)) - **`staleTime` default:** `0`, so cached data is stale immediately. Stale queries may refetch on mount, window focus, or reconnect. Set `staleTime` to keep data fresh for longer. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/important-defaults?utm_source=openai)) - **Changing an option:** changing `staleTime` alone does **not** mean “refetch now.” It changes how freshness is evaluated; the docs describe automatic refetches at triggers such as mount, focus, and reconnect. A key change is different: it switches the query being observed, and the new query can fetch if enabled. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/important-defaults?utm_source=openai)) The cited pages are the current official v5 documentation; they don’t establish a rule that *every* option change triggers a refetch. Citations: - 1: https://tanstack.com/query/latest/docs/framework/react/guides/migrating-to-v5?utm_source=openai - 2: https://tanstack.com/query/latest/docs/framework/react/guides/important-defaults?utm_source=openai - 3: https://tanstack.com/query/latest/docs/framework/react/guides/important-defaults?utm_source=openai

TanStack Query v5 official documentation query keys variables queryFn enabled staleTime default

💡 Result:

Here’s the **TanStack Query v5 (React) quick reference**. The current official docs are served under `/latest`; the points below reflect the v5-style API shown there. - **`queryKey`**: A top-level array that uniquely describes the fetched data. Include any changing variables used by the query function; changing the key can trigger a refetch. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/query-keys?utm_source=openai)) - **`queryFn`**: A function that returns a Promise resolving to data or rejecting/throwing an error. It can receive a context containing the query key. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/queries?utm_source=openai)) - **`enabled`**: `true` by default. Set it to `false` (or a boolean-returning function) to prevent automatic fetching; you can later enable it conditionally. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/reference/interfaces/UseQueryOptions?utm_source=openai)) - **`staleTime`**: **0 ms by default**—data is considered stale immediately. Set a duration to keep it fresh for that period; `Infinity` and `'static'` are also supported, with different invalidation behavior. ([tanstack.com](https://tanstack.com/query/latest/docs/framework/react/guides/important-defaults?from=reactQueryV3&utm_source=openai)) ```tsx useQuery({ queryKey: ['todos', { status, page }], queryFn: ({ queryKey }) => fetchTodos(queryKey[1]), enabled: Boolean(status), staleTime: 60_000, }) ``` This example is illustrative, not a documentation excerpt.

Use React Query’s enabled option for the VS Code LM query.

The current hook runs its query function when enabled is false and stores [] under the static key. The key does not include the changing enabled value, so React Query can reuse that empty result instead of starting a new request when the provider changes.

Suggested fix

export const useVsCodeLmModels = (enabled: boolean) => useQuery({ queryKey: ["vsCodeLmModels"], - queryFn: () => (enabled ? getVsCodeLmModels() : []), + queryFn: () => getVsCodeLmModels(), + enabled, })

…seline for model selector The compact chat model picker added one more focusable trigger between the ApiConfigSelector and AutoApproveDropdown, which pushed the textarea just past the visual test's fixed 10-Tab loop. Widen to 15 iterations so the Tab-driven focus walk reliably lands on the editor before the focus screenshot is taken. Also refresh the electron extension-host sidebar baseline so it reflects the new model selector button in the chat composer.

Guard restricted VS Code LM updates before activation.

getVsCodeLmModels() provides a real model.id, but this picker discards it and persists only { vendor, family }. ProfileValidator checks only vsCodeLmModelSelector.id for restricted profiles. The displayed option can therefore be selected and activated as a profile that validation rejects. Do not fabricate an ID from vendor/family; reject the update until the candidate selector contains an allowlisted ID.

… profiles - useVsCodeLmModels: wire React Query's AbortSignal through to the request helper so unmounting or switching away from the VS Code LM provider removes the window message listener and clears the 10s timeout instead of leaking them. - Add a focused useVsCodeLmModels spec covering the disabled path, matching response resolution, unrelated-message filtering, the missing-array fallback, and listener cleanup. - ChatModelSelector.persistModel: refuse to post upsertApiConfiguration when apiConfiguration.apiProvider is unset. The profile schema strips provider-specific fields from provider-less profiles, so writing openRouterModelId (the hook's default) would silently disappear on reload. - Refresh ChatModelSelector tests: assert the guard rejects writes for provider-less profiles, and verify the stored provider is preserved.
