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.

📝 Summary

Summary by CodeRabbit

New Features
- Added a model selector to the chat composer, with searchable model lists where available. Choices reflect provider support and organization restrictions.
- Model selection is available after choosing an API configuration. Providers without in-app model selection direct you to settings.
- Selecting a model updates the active profile’s configuration.
- The selector includes loading and no-results states.
Localization
- Added translations for model selection, loading, and clearing searches in supported languages.

Walkthrough

The chat toolbar now includes a model selector for supported providers. It filters and searches model lists, then sends selected model changes to update the current provider profile. The selector includes translated labels across supported locales.

Changes

Chat model selection

Layer / File(s)	Summary
Model list and selection behavior `webview-ui/src/components/chat/ModelSelector.tsx`, `webview-ui/src/components/chat/selectorConstants.ts`, `webview-ui/src/components/chat/ModeSelector.tsx`, `webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx`, `webview-ui/src/i18n/locales/*/{chat,common}.json`	`ModelSelector` combines static and fetched models, applies organization allow-list and deprecated-model filtering, and supports search and selection. Tests cover provider behavior, search, selection, and filtering. Locale files add selector, loading, and search labels.
Chat toolbar integration `webview-ui/src/components/chat/ChatTextArea.tsx`, `webview-ui/src/components/chat/__tests__/ChatTextArea.spec.tsx`, `webview-ui/src/components/chat/__tests__/ChatTextArea.visual.tsx`	`ChatTextArea` passes the API configuration and organization allow-list to the selector. It disables the selector when API configuration selection is disabled or no persisted configuration name exists. Model changes post an `updateProfileModel` message. Tests cover the trigger and message; the visual test allows more Tab presses when locating the editor.
Profile model update handling `packages/types/src/vscode-extension-host.ts`, `src/core/webview/webviewMessageHandler.ts`, `src/core/webview/ClineProvider.ts`, `src/core/config/ProviderSettingsManager.ts`, `src/core/webview/__tests__/webviewMessageHandler.updateProfileModel.spec.ts`, `src/core/webview/__tests__/ClineProvider.apiHandlerRebuild.spec.ts`	The webview message type includes `updateProfileModel`. The handler validates incoming fields and delegates accepted updates. `ClineProvider` validates profile and provider state, restricts patch keys and values, and upserts accepted settings with rollback handling. `ProviderSettingsManager` can clear a mode mapping. Tests cover merging, invalid requests, stale updates, and failures.

Merge Risk: 🔵 Low · up to 458ba

The model-update rollback test should verify which mode it clears. This is a bounded coverage gap, not an established failure of model switching, so the change remains mergeable with follow-up.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to f2f4c

Changing models during a profile switch can restore the previous profile and its saved settings. Subsequent requests could therefore use an unintended account or endpoint. Normal selections are filtered and validated, and the change does not establish a new remote attack route.

Retained concerns

Medium · security · inferred: The new model-update transaction does not bind commit-time profile identity or activation to the user's current selection. While a profile switch is pending, the toolbar can still send the previous profile name. The handler reads that profile outside the mutation queue and later upserts it with activation enabled, potentially reversing the completed switch and rebuilding the task client with the previous profile's credentials and endpoint. Concurrent edits can also be overwritten by the stale full-profile snapshot.

Security review details

Security Blast Radius

inferred — The demonstrated exposure is within the extension's saved profiles and current task configuration. An unintended activation can affect subsequent request credentials and destination, mode association, and the profile retained in task history. Cross-tenant, service-wide, or remote unauthenticated exposure was not established.

Security Findings and Attack Paths

inferred — A user can initiate a profile switch and select a model before refreshed state arrives. The model message can still name the previous profile; its later activating upsert can reverse the switch. This source-supported transition concern does not require a malicious message, and actual disclosure to an unintended endpoint has not been demonstrated.

Trust Boundaries and Controls

observed — The message crosses the editor webview-to-host boundary through the existing listener. The production webview has a restrictive content-security policy. Normal model choices are organization-filtered; the host checks provider equality and patch fields, and persistence validates provider-specific schemas. These controls do not bind a queued update to the current active profile.
observed — The new patch allowlist includes credential and endpoint fields, but the merge base already exposed full-configuration save and activating upsert messages through the same webview. Broad configuration authority is therefore preexisting; the evidence does not establish a new privilege escalation solely from adding this message.

Resilience and Maintainability Implications

observed — The reused upsert saves before activation, and its queue advances on timeout while the underlying operation may continue. These failure-containment limitations predate this PR. The new model-update path inherits them; they are not treated as independently introduced defects.

Hardening Proposals

proposed — Make model updates an owner-managed transaction that reads, validates identity and current selection, merges, and commits inside the serialized operation. Use a stable profile identity or revision check and prevent stale updates from reactivating a superseded profile. Exercise switching, repeated updates, concurrent edits, and cancellation recovery as security-relevant transition cases.

Full details: Regression Evidence

Explanation

ProviderSettingsManager.clearModeConfig adds rollback behavior that deletes a stored mode mapping and persists the change, but it has no direct unit test. The new ClineProvider test only asserts that a mocked clearModeConfig is called when activation fails with no prior mapping; it does not verify deletion or persistence. The method’s unset-mapping branch can therefore regress without a focused test. The visible composer change does have updated Playwright snapshots, and the model-selection paths have focused tests.

Resolution

Add a focused ProviderSettingsManager unit test that calls the real clearModeConfig with an existing mode mapping and verifies that the mapping is removed and the updated profiles are stored. Also cover the absent-mapping case to verify that it does not write unchanged profiles.

Full details: Security Boundaries

Explanation

The new updateProfileModel path can bypass an organization model allow-list when the policy is unavailable. It reads organizationAllowList from getState() (ClineProvider.ts:2017) and then relies on ProfileValidator.isProfileAllowed (2067). However, getState() starts with ORGANIZATION_ALLOW_ALL and retains it when CloudService.getAllowList() fails (3098–3105); CloudSettingsService.getAllowList() also returns ORGANIZATION_ALLOW_ALL when settings have not loaded (CloudSettingsService.ts:186–188). If a restricted organization sends an update during that state, the check accepts an unlisted model and the new path saves and activates it (ClineProvider.ts:2078). The provider and patch-key guards do not prevent this allow-list bypass.

Resolution

Make the model-update path fail closed when the organization allow-list is unavailable or has not loaded. Distinguish an explicitly unrestricted policy from a missing or failed policy lookup, and do not save or activate the profile until the current policy is available and the proposed model passes it.

Full details: Persistence Integrity

Explanation

A timed-out model update can roll back newer active settings for the same profile. enqueueProviderProfileMutation advances the queue when the timeout-bounded callerResult rejects, even while the original run is still pending (ClineProvider.ts:275–302). If one activation write then fails late, the rollback checks only whether currentApiConfigName === name (1963–1970). A newer model update can save and activate another model under that same profile name before the old write fails. The saved-profile rollback correctly skips the newer profile data when isStillApplied() is false (1918–1920), but activation rollback still calls setProviderSettings(rollback.previous) and restores the old profile metadata (1976–1982). This leaves the newer persisted model inconsistent with the active ContextProxy settings. updateProfileModel passes rollback data into this path (2012–2018, 2073–2081).

Resolution

Prevent stale activation rollback from overwriting a newer update to the same profile. Track and verify the activation/model version or compare the current settings against the failed mutation’s own values before restoring. Also ensure timeout handling cannot allow late writes and rollback to race with subsequent queued mutations, or make the late operation explicitly abort without touching newer state.

Full details: Lifecycle Resource Cleanup

Explanation

The new model-update rollback can write stale activation state after cancellation. enqueueProviderProfileMutation advances the queue when its 30-second timeout wins, even if the underlying mutation is still pending (ClineProvider.ts:268–303). In the changed upsertProviderProfileUnlocked path, a timed-out mutation can later enter the failed-write rollback at lines 1963–1985. If a newer model update for the same profile has already activated, ownsActivation still passes because it checks only currentApiConfigName === name; the older mutation can then restore the previous provider settings and mode mapping over the newer activation. This is a concrete duplicate rollback after cancellation introduced by the changed activation rollback path.

Resolution

Track activation ownership with a per-mutation generation or token, and run activation rollback only when that exact mutation still owns the activation. Alternatively, keep subsequent mutations blocked until the timed-out operation and its rollback settle. Add a regression test where a timed-out model update is followed by a successful update to the same profile, then the older activation write fails; verify the newer settings and mode mapping remain active.

The chat ModelSelector used to send the webview's full apiConfiguration, which can be the active task's config rather than the profile's, so a model pick could overwrite the profile. Send only a model patch via the new updateProfileModel message; the host merges it onto the stored profile and rejects the update if the provider no longer matches. Reuse handleModelChangeSideEffects for the reset logic and tighten the tests.

case to mock the translation function as an identity function, then assert that
showErrorMessage receives the expected common:errors.save_api_config key. Keep
the existing assertion that no profile is saved.

Review comments at @src/core/webview/webviewMessageHandler.ts:
- Around line 2297-2325: In the model-update handler, prevent stale updates from
saving or activating a profile after a switch: make the queued upsert
conditional on the profile still being current when its mutation runs. Update
the upsertProviderProfile call in this handler and its implementation to skip
the save and activation when the current profile no longer matches the requested
profile.

Review comments at
@webview-ui/src/components/chat/__tests__/ChatTextArea.spec.tsx:
- Around line 1251-1276: In the “disables model selection without a persisted
API configuration” test, replace the filtered `upsertApiConfiguration` assertion
with a full assertion that `mockPostMessage` was not called after clicking the
disabled `model-selector-trigger`.

Review comments at @webview-ui/src/components/chat/ChatTextArea.tsx:
- Around line 951-962: In the history restoration flow, clear
historyItem.apiConfigName when the named profile has no apiProvider, while
preserving the current task configuration. This prevents the stale profile name
from being used by the model selector’s handleModelChange update.

…dling Only allow awsCustomArn to be reset (never set) since the allow-list does not cover it, settle all activation writes and restore the stored profile if any fails, and skip a late rollback when a newer selection has already changed the saved values.

- Around line 1971-1975: Gate the activation-state rollback in the

activation state; do not restore `prevName`, `prevMeta`, provider settings, or
the mode mapping after a newer profile switch has completed. Follow the
ownership check used by the saved-profile rollback, preserving rollback behavior
when no newer mutation has taken ownership.
- Line 1948: Add a `signal.aborted` check immediately after
`getModeConfigId(mode)` resolves and before the activation writes begin, so a
timed-out profile-switch mutation cannot continue after cancellation. Use the
existing cancellation handling in the surrounding mutation flow.

restores the prior state even when getModeConfigId(mode) returned undefined; do
not skip rollback based on modeConfigId being truthy. Use the setModeConfig

… rollbacks Only the stored provider's own model id (plus reset-only fields) is patchable, so the unchecked LM Studio draft model cannot be changed. Recheck cancellation after reading the mode mapping, skip the activation rollback when a newer switch owns the activation, and clear a mode mapping that did not exist before the failed update.
