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 same existing message and ClineProvider.upsertProviderProfile path used by the settings page. No new backend protocol is introduced; the chat selector only changes the modelId field and reuses the existing save/activate/broadcast flow.
  • Adds chat.* i18n keys across all 18 locales and a Playwright visual snapshot for the dark sidebar chat.

Behavioral guarantees (webview-only, introduced by this PR)

  • Trigger reflects the persisted selection, never the transient search text.
  • Webview-side allowlist filtering: the model list is filtered against the organization allowlist in the webview, and the custom-model entry point is hidden for restricted providers. The extension-host validation on upsertApiConfiguration is the pre-existing path shared with the settings page — this PR does not modify it.
  • No silent model switches in the webview: ChatModelSelector.persistSelection is a no-op when the active profile name is unset, so the trigger never writes to an unnamed profile. The trigger is also disabled when apiProvider is missing from the active profile.
  • Single in-flight model discovery per channel: every message-based model hook (router / Ollama / LM Studio / VS Code LM / OpenAI-compatible) shares one stable queryKey and runs through TanStack Query, so only one request is in flight at a time. When the provider switches, React Query aborts the pending AbortSignal, the hook's settled flag short-circuits any late resolution, and the previous message listener is removed synchronously — a stale response therefore cannot repopulate the newly selected provider. OpenAI-compatible providers leave the loading state on empty or failed responses.

Out of scope for this PR: any change to ClineProvider.upsertProviderProfile (allowlist validation, transactional snapshot/rollback, profile persistence semantics). Those are pre-existing concerns of the shared profile-mutation path and should be addressed separately if needed.

Test Procedure

cd webview-ui && npx vitest run src/components/chat/__tests__/ChatModelSelector.spec.tsx src/components/chat/hooks/__tests__/useChatModelSelector.spec.tsx src/components/ui/hooks/__tests__/useVsCodeLmModels.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, plus the updated useVsCodeLmModels and new useChatModelSelector hook specs. ESLint and tsc --noEmit are clean for the changed files and both packages.

49-59: Correlate VS Code LM responses with their requests.

The comment at Lines 8-11 says at most one request is in flight. That is true on the webview side only. If the query is cancelled, the extension handler still replies later. A new request started after the cancel then matches only by type and accepts the reply to the old request. A request ID that the handler echoes back would remove this race. A prior review raised this, and the code has not changed.

This test only checks that the option is listed. Nothing asserts that selecting it posts vsCodeLmModelSelector: { vendor, family }. A prior review raised this, and the gap is still there.

📝 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 the required profile and provider details are available.
    • Added support for selecting VS Code language models by vendor and family.
    • Model selection is unavailable when required configuration details are missing. Custom model options are hidden when provider restrictions apply.
    • Model choices respect provider restrictions and omit deprecated models, except when a deprecated model is already selected.
    • Updated the settings model picker to use the shared model-selection experience.

The chat input now includes a provider-aware model selector. A shared searchable selector serves settings and chat. Chat selections are saved to the active API configuration profile when the required profile data is available.

Changes: Chat model selection

Layer / File(s) Summary
Resolve provider model data
webview-ui/src/components/chat/hooks/useChatModelSelector.ts, webview-ui/src/components/chat/hooks/__tests__/useChatModelSelector.spec.tsx, webview-ui/src/components/ui/hooks/useVsCodeLmModels.ts, webview-ui/src/components/ui/hooks/__tests__/useVsCodeLmModels.spec.tsx
The chat 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 handles matching responses, timeouts, and aborts. Tests cover provider resolution and request behavior.
Use shared model selection UI
webview-ui/src/components/ui/model-select/ModelSelect.tsx, webview-ui/src/components/settings/ModelPicker.tsx
ModelSelect provides searchable model options, provider and organization filtering, deprecated-model handling, and optional custom-model selection. ModelPicker delegates its selection UI to ModelSelect and retains value transformation, callbacks, and one-time default initialization.
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 displays provider model options and posts selected models to the active profile when required profile data is available. Tests cover labels, persistence, missing profile data, restricted options, and focus behavior.

Explanation

The PR satisfies the coding requirements in [#1502]. ChatTextArea mounts ChatModelSelector beside the API configuration selector. The selector supports static and dynamic provider models, search, deprecated-model handling, compound VS Code LM values, and persisted model changes for the active profile. Unsupported or unavailable configurations disable selection without posting a change. The PR adds chat.* translations across all 18 locales and automated component, hook, model-discovery, and visual-test coverage.

Full details: Out of Scope Changes check

Explanation

The changes remain within [#1502]. ModelSelect, the ModelPicker integration, provider model discovery, organization filtering, profile-selection persistence, localization, regression tests, and visual-test updates support the chat model-selector feature or shared model-selection behavior. The available evidence does not establish an unrelated change. The excluded screenshot files do not affect this assessment.

Full details: Description check

Explanation

The description includes the linked issue, implementation details, test procedure and results, checklist, visual snapshot details, and documentation impact. The optional Additional Notes and Get in Touch sections are omitted, but the description is otherwise complete and actionable.

Full details: Security Boundaries

Explanation

The allowlist bypass remains unresolved. The changed ChatModelSelector.persistSelection posts the complete profile and selected model through upsertApiConfiguration (webview-ui/src/components/chat/ChatModelSelector.tsx:41-55). The selector filters models only in the webview (ModelSelect.tsx:83-93), so a crafted webview message can supply a disallowed model. The host handler forwards that profile without validation (src/core/webview/webviewMessageHandler.ts:2305-2308), and upsertProviderProfile saves and activates it (src/core/webview/ClineProvider.ts:1887-1913). ProfileValidator.isProfileAllowed is only called during task creation (ClineProvider.ts:3412-3414). With an organization allowlist that permits only selected models, a crafted message can persist and activate a disallowed model.

Resolution

Validate the complete incoming profile in the extension host before saving or activating it. Use the current organization allowlist with ProfileValidator.isProfileAllowed, reject invalid upsertApiConfiguration updates, and preserve the previous profile and task configuration when validation or activation fails.

Full details: Persistence Integrity

Explanation

The new chat path activates a non-atomic profile persistence flow. ChatModelSelector.persistSelection posts upsertApiConfiguration with the changed model (webview-ui/src/components/chat/ChatModelSelector.tsx:41-55), and webviewMessageHandler awaits upsertProviderProfile (src/core/webview/webviewMessageHandler.ts:2305-2308). upsertProviderProfile saves the profile first, then performs separate list, active-profile, mode-binding, and context writes with Promise.all (src/core/webview/ClineProvider.ts:1887-1909). Its catch logs the error and returns without rollback (src/core/webview/ClineProvider.ts:1924-1930). If setModeConfig or another propagation write fails after saveConfig succeeds, the selected model remains persisted while activation state or context can remain stale. This is a concrete changed caller activating the partial-failure path.

Resolution

Make the chat profile update transactional. Snapshot the existing profile, profile list, active-profile name, mode binding, context provider settings, and task state before mutation. Restore every changed value when any activation or propagation step fails, and report the partial failure. Alternatively, replace the separate saves and activation writes with one atomic persistence operation.

Full details: Regression Evidence

Explanation

Focused coverage remains incomplete. useChatModelSelector passes sentinel IDs to useOllamaModels and useLmStudioModels when no model is configured (useChatModelSelector.ts:89-94), but the hook tests only stub results and do not assert those arguments (useChatModelSelector.spec.tsx:88-127). The hook also reads state-backed models for LiteLLM and Poe and disables useRouterModels for those providers (useChatModelSelector.ts:42-53, 82-85, 113-118), but no direct test supplies routerModels for either provider or verifies the remote query is disabled. The chat composer Playwright snapshots and VS Code LM lifecycle coverage are present.

Resolution

Add direct useChatModelSelector tests that assert useOllamaModels("ollama") and useLmStudioModels("lmstudio") when the model is unset. Add a LiteLLM or Poe test with provider models in extension state and assert those models are returned while useRouterModels is called with fetching disabled. Retain the existing VS Code LM lifecycle tests and chat composer snapshots.

Full details: Lifecycle Resource Cleanup

Explanation

The lifecycle leak remains. useChatModelSelector calls useVsCodeLmModels(activeProvider === providerIdentifiers.vscodeLm) at useChatModelSelector.ts:95, while the chat component stays mounted during provider changes. useVsCodeLmModels keeps the constant query key ['vsCodeLmModels'] and only changes enabled at useVsCodeLmModels.ts:62-67. Disabling the observer does not remove it or cancel its active fetch. Therefore, a VS Code LM request keeps the window message listener and 10-second timer in getVsCodeLmModels at lines 32-59 until a response or timeout. The tests cover explicit queryClient.cancelQueries, but no enabled-to-disabled rerender path.

Resolution

Cancel the active vsCodeLmModels query when enabled changes to false, or make the query identity include the active provider/enabled state so the old observer is removed and its abort signal reaches getVsCodeLmModels. Add a regression test that rerenders from enabled to disabled, verifies removeEventListener and timer cleanup, and confirms a later VS Code LM response cannot populate the query.

@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.

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).

🟡 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.

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.

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" }.

Proposed addition
 		expect(screen.getByTestId("model-option-copilot/gpt-4o")).toBeInTheDocument()

…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.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

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.

53-53: 🎯 Functional Correctness

Use the query’s enabled option instead of caching a disabled result.

When enabled is false, this query stores [] under the same key used for an enabled request. Changing only the captured enabled value does not change that key. Use enabled as a query option so the false-to-true transition starts the model request. This concern was raised in a previous review. TanStack Query documents both conditional queries and query-key dependencies. (tanstack.com)

Correlate VS Code LM responses with their requests.

When the query is canceled and then remounted, the extension can reply to the old request after the new request starts. The new listener matches only the message type, so it can resolve with the old model list. Include and echo a request ID, then accept only the matching response.

… 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.

67-67: The trigger stays enabled when apiProvider is unset, so selections are silently dropped.

On Line 46, persistSelection returns early when apiConfiguration.apiProvider is missing. However, isDisabled on Line 67 does not check apiProvider. The hook falls back to OpenRouter, so the user can still open the list and pick a model. Nothing is saved, and the user gets no feedback.

Add !apiConfiguration?.apiProvider to isDisabled.

Proposed fix
-	const isDisabled = disabled || !modelIdKey || !currentApiConfigName
+	const isDisabled = disabled || !modelIdKey || !currentApiConfigName || !apiConfiguration?.apiProvider

The settings popover no longer matches the trigger width.

ModelPicker now always passes renderTrigger. Because of that, Line 160 always applies w-[300px], and Line 164 always applies align="start" in Settings. The class w-[var(--radix-popover-trigger-width)] then has no effect for either caller. The comment on Lines 158-159 says Settings keeps the old layout, but no caller reaches that path. The result is a visible change: the settings model list is 300px wide instead of matching the full-width combobox.

Choose the compact layout with an explicit prop, not with the presence of renderTrigger.

Proposed fix
+	/** Compact popover anchored under the trigger (chat input). */
+	compact?: boolean
 ...
-					renderTrigger && "w-[300px]",
+					compact && "w-[300px]",
 ...
-				align={renderTrigger ? "start" : undefined}
-				sideOffset={renderTrigger ? 4 : undefined}>
+				align={compact ? "start" : undefined}
+				sideOffset={compact ? 4 : undefined}>

Then pass compact from ChatModelSelector.

Update ModelSelect’s popover layout to use an explicit compact-layout prop
rather than renderTrigger, so settings retain the trigger-width layout and
default alignment while compact chat popovers keep their fixed width and trigger

- ModelSelect: remove popover width dead-code ternary; all callers pass
  renderTrigger so align/sideOffset/width are now constants.
- ChatModelSelector: include !apiConfiguration?.apiProvider in isDisabled
  so the trigger no longer opens a picker whose selection would be
  silently discarded by persistSelection guard.
- useVsCodeLmModels: document why no requestId correlation is needed
  (stable query key => at most one in-flight queryFn invocation).
- useVsCodeLmModels.spec: assert removeEventListener receives the same
  handler reference that addEventListener registered, instead of
  expect.any(Function).
- ChatModelSelector.spec: rename the provider-less case to assert the
  trigger is disabled and the popover cannot be opened.
…opover width

- useVsCodeLmModels: reject immediately if signal is already aborted before
  registering message listener or starting the timer. Extract abort handler
  into a named function registered with { once: true }, and remove it in
  cleanup. finish() now only checks settled, leaving abort semantics to
  the handler.
- useVsCodeLmModels.spec: add an abort-path test that cancels the query,
  asserts the registered message handler is removed, and verifies a late
  response does not populate result.current.data.
- ModelPicker: pass contentClassName w-[var(--radix-popover-trigger-width)]
  so the settings popover follows its combobox trigger width while chat
  keeps the 300px compact default. twMerge resolves the w-* conflict.

…, add useChatModelSelector hook spec

- useVsCodeLmModels: export getVsCodeLmModels so tests can exercise the
  already-aborted signal branch directly without going through React Query.
- useVsCodeLmModels.spec: add a timeout-path test using fake timers (advance
  10s, assert listener removed and error state populated), and an
  already-aborted test that asserts no listener is registered, no timer
  starts, and no postMessage is sent.
- useChatModelSelector.spec (new, 7 cases): cover router, ollama, lmstudio,
  vsCodeLm (with valueTransform/displayTransform round-trip and null
  boundary), static anthropic, default openrouter fallback, and retired
  provider handling.
…rt-circuit

useChatModelSelector.spec: assert mockUseVsCodeLmModels is called with false for every non-vscodeLm branch (openrouter/ollama/lmstudio/anthropic/default-openrouter/retired) and true only for vscodeLm, so a future regression that opens the vscode-lm request on the wrong provider fails.

useVsCodeLmModels.spec: timeout test now reuses the wrapper() helper instead of inlining a QueryClient/Provider pair. already-aborted test now spies on globalThis.setTimeout and AbortSignal.prototype.addEventListener to assert the early-return path never installs timers or abort listeners; all four spies restored in try/finally so they do not leak into sibling tests.

🟡 Minor · Gate the query with TanStack Query's enabled option. · useVsCodeLmModels.ts:62-66

webview-ui/src/components/ui/hooks/useVsCodeLmModels.ts:62-66
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Gate the query with TanStack Query's enabled option.

For non-VS Code LM providers, the current query resolves [] and stores it under the shared ["vsCodeLmModels"] key. Switching providers only changes the value captured by queryFn; it does not change the observer's enabled state. The selector can therefore keep exposing the cached empty model map until another refetch trigger occurs.

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

This prevents the disabled path from caching [] and triggers a stale-query refetch when the observer changes from disabled to enabled. A failed refetch can still retain previously cached data, including a legitimate empty result; this fix targets the provider-switch cache pollution.

Match responses to requests with a requestId.

handler accepts any vsCodeLmModels message. A query can be canceled and then started again, for example on unmount and remount. In that case, the late reply to the canceled request resolves the new request. The handler in src/core/webview/webviewMessageHandler.ts:1483-1487 sends no correlation ID back. The PR description says model-discovery responses are matched by requestId, but this path does not do that. Send a requestId, echo it from the extension handler, and check it in handler.

…el option

Previously the hook short-circuited inside queryFn: ({ signal }) => enabled ? getVsCodeLmModels(signal) : []. That let React Query cache an empty array under the shared query key for non-vscodeLm providers, so switching back to vscodeLm could read the stale empty cache instead of re-issuing the request. Now enabled is passed as a top-level useQuery option, so TanStack Query simply does not invoke queryFn when disabled.

Disabled spec now asserts both vscode.postMessage and window.addEventListener('message') are untouched after fetchStatus settles to idle, proving queryFn never runs rather than returning [].
