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.

Reviewers should pay attention to the provider/model resolution branches and the modelIdKey selection for storage.

- ChatModelSelector popover lives in the chat input bar, showing the active model for the current API profile.
- useChatModelSelector resolves the provider's model list: static per-provider defaults, router catalog (OpenRouter, Requesty, etc.), and custom models, and picks the matching modelIdKey for storage.
- Deprecated models are filtered out, except the currently selected one; the list supports search.
- Selecting a model posts upsertApiConfiguration for the active profile; the backend persists it, activates it, and broadcasts the updated apiConfiguration back to the webview.
- Covers compound provider values (e.g. VSCode LM selector) with value/display transforms.
- Add ChatModelSelector.spec.tsx and useChatModelSelector.spec.tsx.

Summary by CodeRabbit

  • New Features
    • Added a searchable model picker beside the chat configuration selector. Browse available models or enter a custom model ID, with deprecated models hidden unless currently selected.
    • Model selection is available across supported providers, with loading and empty-list states shown when applicable.
    • Added localized model-selection text across supported languages.

Walkthrough

Adds a searchable model selector to chat. A new hook resolves provider model lists, configuration keys, defaults, loading state, and optional value transforms. Selecting a model updates the current API configuration.

Merge Risk: 🟡 Moderate · up to 62c52

The chat model picker can offer the wrong Z.AI models for mainland users, and keyboard-only users cannot pick a model. Fix both before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 62c52

The picker updates saved choices and initiates provider discovery using existing credentials. No newly exploitable security failure was established, but policy enforcement during retries and recovery remains partly unresolved.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly affected assets are the user's captured active profile, the current task's API client, and configured discovery endpoints. Selecting a custom ID requires interaction with the extension UI; the selection handler does not itself introduce a new credential or endpoint.

Security Findings and Attack Paths

  • inferred — A prohibited custom value can cross display filtering into profile persistence and current-task configuration. However, existing settings already provide custom selection and upsert routes, and task creation retains policy validation. The inspected retry path reuses the current API client, but its complete authorization chain and equivalent baseline save restrictions remain unresolved; a newly introduced executable policy bypass is not established.

Trust Boundaries and Controls

  • observed — OpenAI-compatible discovery now runs from the mounted chat hook using the configured URL, key, and headers. The existing extension handler sends the key as a bearer credential to that URL's models endpoint. Settings already used this same credential-bearing discovery path; the PR changes initiation timing rather than adding endpoint-selection authority.

Hardening Proposals

  • proposed — Consider a backend policy-checked model-only update keyed by stable profile identity and revision, with explicit failure and timeout recovery. This would reduce dependence on display filtering and stale full-configuration snapshots; it is a hardening proposal, not a verified new vulnerability.

Full details: Regression Evidence

Explanation

Coverage is missing for changed selector behavior. ChatModelSelector.tsx filters the provider allow-list and hides deprecated models while retaining the selected model (lines 20–31), but its tests use only allowAll: true and non-deprecated models, so they do not check those rules. The test titled “no apiConfiguration” does not unset apiConfiguration; it unsets modelIdKey instead, so the separate missing-configuration early return at lines 60–61 is not tested. The UI change also has no updated Playwright component snapshot: only the Electron end-to-end screenshot changed, while the existing ChatTextArea.visual.tsx component snapshot images did not.

Resolution

Add focused component tests with an organization allow-list and deprecated models, including a deprecated currently selected model. Add a test that leaves modelIdKey set but makes apiConfiguration undefined, then verify selection does not post a message. Add or update the Playwright component snapshot for the chat composer so it captures the new model selector.

Full details: Persistence Integrity

Explanation

The new selector adds a model-persistence path: ChatModelSelector.tsx:73-80 posts upsertApiConfiguration with the updated profile. The handler awaits upsertProviderProfile (webviewMessageHandler.ts:2281-2284), which saves the profile first (ClineProvider.ts:1879-1885) and then runs four activation/state writes in Promise.all (ClineProvider.ts:1889-1907). If one state write fails after the profile save, the profile and active state can diverge. The catch at ClineProvider.ts:1922-1928 logs and shows an error, but it does not roll back completed writes or reconcile the profile and active state. The new selector can therefore persist a model selection while the active consumer still has the prior configuration.

Resolution

Make profile persistence and activation atomic, or record the prior profile and state and restore them if any activation write fails. If rollback is not possible, explicitly handle partial success by reconciling the active configuration from the saved profile and reporting which changes persisted before returning failure.

Full details: Lifecycle Resource Cleanup

Explanation

The new message-based model request effect can duplicate backend work during React StrictMode effect replay. webview-ui/src/index.tsx:13-16 mounts the app inside &lt;StrictMode&gt;. In useChatModelSelector.ts:183-211, the effect posts a request for active message-based providers and returns no cleanup or deduplication. For example, an active Ollama provider can post requestOllamaModels twice during the development mount replay. The handler processes each request with a cache flush and model fetch (src/core/webview/webviewMessageHandler.ts:1382-1418).

Full details: Description check

Explanation

The description explains the implementation and includes test steps, checklist details, and visual snapshot information. However, it does not link an approved GitHub issue; it says the issue will be added later, and the Issue Linked checklist item is unchecked.

- Around line 202-231: In ChatModelSelector tests, separate the existing
unset-modelIdKey case from the missing-configuration guard, then add a test with
modelIdKey set and apiConfiguration undefined via mockUseExtensionState; verify
selecting an option does not post a message.

Review comments at @webview-ui/src/components/chat/ChatModelSelector.tsx:
- Around line 140-155: Update the model-selection controls in the
ChatModelSelector popover: make the options rendered by filteredModelIds.map and
the custom-model choice keyboard-operable, and give the search input and popover
keyboard navigation and selection behavior. Render the clear-search control as a
button with an accessible name so it can be activated by keyboard.

Review comments at
@webview-ui/src/components/chat/hooks/__tests__/useChatModelSelector.spec.tsx:
- Around line 53-69: Add a regression test in the static providers suite for the
Z.AI provider configured with `zaiApiLine: "china_coding"`, asserting the exact
`defaultModelId` and returned model keys for that API line. Replace the existing
truthiness check for Anthropic’s `defaultModelId` with an assertion against its
exact expected constant.

Review comments at
@webview-ui/src/components/chat/hooks/useChatModelSelector.ts:
- Around line 183-217: Update the model-request effect in the
useChatModelSelector hook to depend on a serialized value of openAiHeaders
rather than the object reference, preventing equivalent configuration updates
from repeating the OpenAI request; also reset the model list when activeProvider
changes so models from the previous provider are not retained.
- Line 335: Pass apiConfiguration as the third argument to
getStaticModelsForProvider in the MODELS_BY_PROVIDER branch of the model
selector, so the static model list respects the configured Z.AI mainland models.
Keep the existing provider lookup and fallback behavior unchanged.

Test the missing-configuration guard separately.

The trigger click does not rerender this test: the mocked Popover ignores onOpenChange, and the mocked trigger receives no onClick prop. The selection uses the one-time hook return with modelIdKey unset. However, apiConfiguration remains set, so the test does not cover that guard. Keep the unset-key case and add a case with apiConfiguration: undefined and modelIdKey set.

Make model choices and the clear-search control keyboard-operable.

The search input has no selection key handler, and the popover adds no model-option navigation. The model choices and custom-model choice are click-only divs; the clear-search control is a click-only span. Render these controls as buttons, or use the existing cmdk primitives.

🐛 Suggested fix
-								<div
+								<button
+									type="button"
 									key={modelId}
 									onClick={() => onSelect(modelId)}
 									data-testid={`chat-model-option-${modelId}`}
 									className={cn(
-										"px-3 py-1.5 text-sm cursor-pointer flex items-center gap-2",
+										"w-full text-left px-3 py-1.5 text-sm cursor-pointer flex items-center gap-2",
 										"hover:bg-vscode-list-hoverBackground",

 										{modelId}
 									</span>
 									{modelId === displayValue && <span className="codicon codicon-check text-xs" />}
-								</div>
+								</button>

Also render the custom-model choice and clear-search control as buttons. Give the clear-search button an accessible name.

Add a regression test for the Z.AI mainland API line.

No test covers zai with zaiApiLine: "china_coding". That test should assert both defaultModelId and the model keys returned. This is the branch where the list and the default currently disagree. Also, defaultModelId is checked only with toBeTruthy(). Assert the exact default constants instead.

🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

The OpenAI model request runs again on every new openAiHeaders object.

The effect lists apiConfiguration?.openAiHeaders as a dependency. That value is an object. The backend sends a new apiConfiguration after each upsert. The hook's own model selection triggers an upsert, so each selection posts requestOpenAiModels again, and the request includes the API key. The model list also persists when the provider changes, because state is never reset. Key the effect on a serialized value such as JSON.stringify(openAiHeaders).

Update the model-request effect in the useChatModelSelector hook to depend on a

Pass apiConfiguration to the static model helper.

For Z.AI’s china_api line, the selector can show glm-5.3, which the configured mainland model list excludes. MODELS_BY_PROVIDER already contains Z.AI, so the extra zai condition is unnecessary.
