Custom models supplied through a proxy cannot currently be hidden in T3 Code without removing their definitions. I want to keep those models available to my harnesses while showing a smaller list in T3 Code.

This extends the existing per-instance visibility control to custom models. Hide means remove from discovery, not disable execution or replace saved selections. It replaces #29743 with a single implementation built around that distinction.

Behavior

Where the custom model is used	After hiding it
Running turns, queued work, existing threads and saved drafts	Keep the model and options; no cancellation or substitution.
Explicit environment/project defaults	Keep the default, including when creating new threads.
Configured rate-limit fallback	Keep using it when applicable; display metadata follows the effective selection.
Text generation, source-control writing and review guides	Keep explicit selections and existing inheritance.
Saved scheduled tasks	Keep execution unchanged and show the saved model accurately when editing.
Selected-model display	Keep the correct name, capabilities and controls, and indicate that it is hidden.
Ordinary picker rows, search, favorites and MCP model discovery	Omit it, even while selected. Switching away does not make it selectable again.
Explicit known model references from agents	Remain valid. Visibility is not an authorization boundary.
Last-used/carry-over hints for genuinely new threads	Skip hidden models; saved drafts and explicit defaults are not convenience hints.
Automatic selection with no saved reference	Use a visible candidate. If none exists, require a model instead of silently choosing a hidden one.

Selected-model metadata comes from the full configured catalog; new choices come from its visible subset. Web/desktop and mobile use that separation rather than putting the selected hidden model back into the dropdown. Server discovery and automatic delegation choices also honor visibility, while explicit references and same-instance inheritance remain valid.

Hide/show reuses the existing preference, keeps custom definitions, options, ordering and favorites, and is reversible per provider instance. No settings schema, proxy configuration or provider adapter changes are needed. This does not introduce a universal retention policy for saved hidden built-in models: their existing selection-resolution rules remain in place. Automatic choices use visible candidates for both kinds.

Verification

Regression tests fail before the fixes for selected hidden models leaking into choices and automatic delegation picking a hidden custom model.
vp run check:changed passes: formatting, lint, knip, affected-package typechecks, 279 adjacent tests, 24 cross-file regression checks and React Compiler checks.
Both picker browser tests pass, including a hidden selected label remaining visible without offering the model as a choice.
In the isolated web client, selected a custom model, hid it and reloaded: its label, reasoning control and Hidden badge stayed correct. It was absent from the open picker and from search after switching away. No paid provider turns were run.
Native mobile and the Electron shell were not manually exercised; mobile logic is covered by focused tests and typechecking. Desktop shares the web implementation.

Screenshots

Before: custom models have no usable visibility switch.

After: custom models use the same visibility control as built-in models.

Scope and discussion

Discussion: #29735. Supersedes the closed #29743, including its unresolved selected-metadata/fallback concerns. The discussion remains open for feedback; it is not maintainer approval.

This is submitted under the focused-configuration route: it extends the existing model-visibility capability to custom entries. The additional selection changes keep visibility from rewriting saved custom references or silently choosing hidden models. It does not add grouping, presets or proxy-side filtering.

Implemented with GPT-6.1 Sol via Codex CLI. The earlier Claude review was of the superseded implementation, not this replacement.

Ssamaluk6d ago

Intentional, not changing. This path only runs when the reused draft is empty and has no explicit model pick, so New Thread is presenting it as a fresh thread. It should resolve the same way a newly created draft would, and new automatic choices skip hidden models. Keeping the hidden sticky model here would make New Thread pick different models depending on whether an empty draft happened to exist. Explicit picks (hasExplicitComposerModelSelection) are untouched, and the sticky selection itself is still stored.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Custom models can now be hidden without deleting their configuration, with hidden labels retained for saved selections. Automatic model defaults also change to skip hidden models, requiring human confirmation of the new selection and all-hidden behavior.

Walkthrough

Hidden-model preferences now apply to built-in and custom models across web, mobile, and MCP flows. The changes update provider visibility controls, model catalogs, picker choices and labels, saved and default selections, and scheduled-task model resolution.

Changes: Model Visibility

Layer / File(s)	Summary
Model catalogs and selection resolution `apps/web/src/modelSelection.ts`, `apps/web/src/modelSelection.test.ts`, `apps/web/src/providerInstances.ts`, `apps/web/src/providerInstances.test.ts`, `apps/mobile/src/lib/modelOptions.ts`, `apps/mobile/src/lib/modelOptions.test.ts`, `apps/web/src/components/chat/providerIconUtils.ts`	Web and mobile model catalogs mark hidden options and exclude them from ordinary choices. Selected-model helpers preserve hidden-model metadata, and default selection resolves against visible models.
Provider visibility controls `apps/web/src/components/settings/ProviderModelsSection.tsx`, `docs/user/project-settings.md`	Provider settings now hide, show, count, group, and bulk-toggle custom and built-in models. Removing a custom model also removes its hidden preference. The project settings documentation describes the controls.
Picker filtering and selected-model display `apps/web/src/components/chat/ChatComposer.tsx`, `apps/web/src/components/chat/ModelPickerContent.tsx`, `apps/web/src/components/chat/ProviderModelPicker.tsx`, `apps/web/src/components/chat/ProviderModelPicker.browser.test.tsx`, `apps/mobile/src/components/ComposerModelControl.tsx`, `apps/mobile/src/features/settings/ScheduledTaskPickerScreens.tsx`, `apps/mobile/src/features/settings/SettingsScheduledTasksRouteScreen.tsx`, `apps/mobile/src/features/threads/ThreadComposer.tsx`, `apps/mobile/src/features/threads/ThreadSettingsSheet.tsx`, `apps/mobile/src/features/threads/new-task-flow-provider.tsx`	Picker choices exclude hidden models. Picker labels and thread settings identify saved hidden selections, and mobile screens resolve selected options with hidden models included.
Defaults, sticky selections, and scheduled tasks `apps/web/src/components/chat/DraftHeroHeadline.tsx`, `apps/web/src/components/settings/scheduledTasksSettings.logic.ts`, `apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts`, `apps/web/src/composerDraftStore.ts`, `apps/web/src/composerDraftStore.test.ts`, `apps/web/src/hooks/useHandleNewThread.ts`, `apps/web/src/hooks/useHandleNewThread.test.ts`, `apps/web/src/providerInstances.ts`, `apps/web/src/providerInstances.test.ts`, `apps/mobile/src/features/threads/new-task-flow-provider.tsx`	Default and sticky selection paths filter hidden models. Scheduled-task fallback resolution excludes hidden models, while configured selections remain selected. Tests cover hidden and visible selection cases.
MCP model listing and delegation `apps/server/src/mcp/OrchestratorMcpService.ts`, `apps/server/src/mcp/OrchestratorMcpService.test.ts`	MCP model listings exclude hidden models. Delegation selects a visible model when no requested or inherited model applies.

Full details: Title check

Explanation

The title "feat(settings): hide custom models without changing saved selections" matches the main change. The diff extends the existing per-instance model visibility control to custom models, and the hidden state leaves saved selections, defaults, and running work unchanged. It follows the conventional commit format the template suggests.

Full details: Description check

Explanation

The description follows the template's sections (Problem, Change, Scope and approval, Verification) and fills in each one with specific content. The Problem is stated: custom proxy models cannot be hidden without removing their definitions. The Change is a per-instance visibility extension. Scope cites the focused-configuration route and a discussion link, and it says plainly that the discussion is not maintainer approval. Verification lists tests, a manual web check, and states what was not checked (native mobile and Electron). The before/after screenshots are present. The Scope section is the weakest part: it relies on the focused-configuration exemption, and the reviewer must judge whether that exemption applies. That is a review question, not a missing section.

Full details: Out of Scope Changes check

Explanation

The changed files support the stated custom-model visibility behavior. They cover hidden-model settings, picker and selected-model metadata, saved selections and defaults, scheduled tasks, mobile flows, MCP discovery, automatic delegation, and regression tests. The documentation describes the same behavior. No unrelated change is demonstrated.

Preserve the accepted model on receipt replay.

If the first model is hidden, the original request selects a later visible model. A retry skips settings and selects the hidden model instead. If the request includes options supported only by the original model, validation returns invalid_request before dispatch can replay the receipt. The target contract permits options without an explicit model. (raw.githubusercontent.com)

Use the committed model selection for replay, or bypass model-dependent validation for an accepted receipt.

✅ Confirmed as addressed by @samaluk

Ssamaluk6d ago

Fixed in d90f0dea8a: default-model resolution reads visibility preferences on receipt replays too, so a retry resolves the same visible model the accepted request validated. A test covers the replay path. The remaining gap is a user changing visibility between the original call and its retry, with model-specific options and no explicit model. That seemed too narrow to justify looking up the committed child selection before dispatch.

CcoderabbitaiBot6d ago

@samaluk The supplied code confirms that receipt replays now read visibility preferences. This addresses the original mismatch when visibility preferences stay unchanged.

If visibility changes between calls, model resolution can still select a different model and reject model-specific options before receipt replay. Understood that you are leaving this narrower case outside this fix. Would you like a follow-up issue for it?

If you found this review helpful, would you consider giving us a shout-out on X?

Thank you for using CodeRabbit!

Review thread resolved.

_{You are interacting with an AI system.}

Ssamaluk6d ago

No follow-up needed, thanks. That case requires a visibility change between a request and its retry, plus model-specific options with no explicit model.

CcoderabbitaiBot6d ago

@samaluk Understood. I won’t open a follow-up issue or request further changes for that edge case.

Match instanceId in getSelectedModelOption.

buildModelOptions is called with selection.instanceId as the locked provider. matchesLockedProvider also admits other instances of the same driver that share the same continuation.groupKey. For example, codex and codex_work can both be returned, and both can expose the same model slug. The existing test "keeps accounts in the continuation group" shows this.

The .find compares only option.selection.model. It can therefore return the option of a different account. The consequences are the wrong provider badge, label and icon, and the wrong capabilities. The capabilities value feeds resolveProviderOptionDescriptors. The removed callers matched both the instance ID and the model.

Compare instanceId as well.

@samaluk Thanks. The supplied code now matches both instanceId and model, which prevents selection of another account’s option in the continuation group.

Do not treat hidden models as unavailable.

useScopedModelDisabledReason returns “This model is unavailable on …” when the matching option is hidden. ProjectDefaultsSettings uses this result for a saved selection, so hiding a saved model can show a misleading status and suppress its effort controls.

The picker already excludes hidden options from new selections. Remove the hidden check from this availability validation.

Do not return an empty model when the instance entry is missing.

resolveAppModelSelectionForInstance returns null in two cases: when the instance has no entry in providers, and when no visible option remains. The new "" fallback treats both as "all hidden." When the entry is missing and the instance has any hidden model, baseModel becomes "". The saved threadModelSelection.model is then ignored.

Return "" only when the instance entry exists and has no visible option. Otherwise keep the previous fall-through.

Fixed in 7f529e4c90. CI checks the PR merged with main, and main's Effect upgrade added NodeCrypto.layer to this file's test layers. I folded the replay case into the existing driver-only delegation test as an it.effect.each row, so it shares those layers, and confirmed that the branch merged with main is the tree that typechecks.

CcoderabbitaiBot6d ago

@samaluk Thanks for the fix in 7f529e4c90. The supplied code confirms that the replay case now shares the driver-only test setup through it.effect.each. Your merged-with-main typecheck confirmation addresses the missing-service concern.

Fixed in 55795976c0. When no model is requested or inherited, driver-only selection now skips instances whose models are all hidden, so a later eligible instance with a visible model is used. Explicit and inherited selections are unchanged. The driver-only test fixture now includes an enabled, fully hidden instance ordered before the expected one.

fix(server): delegation retries reach their receipt after models are hidden169d550

Ssamaluk6d ago

Addressed CodeRabbit's follow-up review (replays after hidden-model changes) in 169d550844: a retry of an accepted delegation still prefers a visible model, but falls back to any advertised model instead of failing, so hiding a model after acceptance can't turn the retry into model_unavailable. New requests still filter hidden models. The driver-only delegation test table has a new row for it.

Ssamaluk6d ago

Fixed in fad6c0d5e9. Visibility is now checked after project enablement, so when every enabled instance of the driver hides all its models, the request fails with model_unavailable and asks the caller to pass target.model or unhide a model. Disabled instances still get the not-enabled error. The driver-only delegation test table has a new row for this case; it fails on the previous commit with provider_unavailable.

CcoderabbitaiBot6d ago

@samaluk The supplied resolveTarget code addresses this finding. It checks project enablement before model visibility. When all enabled candidates have hidden models, it returns model_unavailable with guidance to pass target.model or unhide a model. When no candidate is enabled for the project, it preserves the existing provider_unavailable error.

Replay of an accepted delegation can fail on a settings read it does not need.

When a delegation request is already accepted and no target.model is supplied, resolveTarget reads serverSettings.getSettings before dispatch. The read fails with orchestration_error if it errors. The replay then never reaches threadManagement.dispatch, so the already accepted receipt is not returned. The settings value is needed only by fallbackModel, and an accepted replay with an inherited model does not use it. The read can therefore fail the request without affecting the model choice.

Suggested fix

Read settings only when a replay needs a fallback model, and treat a read failure on a replay as non-fatal. Verify the exact guard before applying this change, because the current code reads settings for any request that has no explicit model.
