I route every model through my proxy so each harness can use all of them, but T3 Code is where I pick models, and there was no way to hide the custom ones I don't want to see without deleting them.

Now custom models get the same picker switch as built-in models in Settings → Providers. Hiding a model takes it out of discovery and automatic choices. It doesn't disable the model or rewrite saved selections that already use it.

This replaces https://git.cafe/pingdotgg/t3code/pulls/29833 (and https://git.cafe/pingdotgg/t3code/pulls/29743 before it) with the same behavior, rebuilt on current main as a series that reads commit by commit. Each commit passes check:changed and its own tests on its own:

1. refactor: look up selected models in the full catalog, offer only visible ones. Separates the configured catalog, where hidden models are flagged, from visible choices. Built-in models only, so behavior is unchanged.
2. feat(settings): custom models can be hidden from pickers. The Settings switch and bulk toggle cover custom models on web and mobile.
3. fix: defaults and fallbacks skip hidden models. Covers the composer, the derived project default and the scheduled-task default, plus empty and blocked states when everything is hidden.
4. fix: new threads don't reuse a hidden model. Covers the last-used (sticky) selection, carrying the current thread's model, and mobile new tasks.
5. fix(server): delegated tasks skip hidden models. Covers MCP discovery, driver-only targets and receipt replays.
6. docs(user): explain hiding models from pickers.

Behavior

Where the hidden custom model is used	After hiding it
Running turns, queued work, existing threads and saved drafts	Keep the model and its options. Nothing is cancelled or substituted.
Explicit environment and project defaults, saved scheduled tasks	Keep using it, and show it as hidden when edited.
Selected-model display	Keeps the right name, capabilities and controls, with a Hidden badge.
Picker rows, search, favorites and MCP model discovery	Omit it, even while it is selected.
Last-used and carry-over model for new threads	Skip it. Unhiding the model restores the remembered choice.
Automatic choice with no saved selection	Uses a visible model. If none is visible, asks you to show one instead of silently picking a hidden one.
Agents naming the model explicitly	Still works. Visibility is not an authorization boundary.

Hide and show reuse the existing per-instance preference, so custom definitions, options, ordering and favorites are kept, and the change is reversible. There are no settings schema, proxy or provider adapter changes. Saved selections of hidden built-in models keep their existing resolution rules; this PR doesn't change them.

Verification

• Each commit's new tests fail on the commit before it, for the reason the commit fixes.
• vp run check:changed passes on every commit.
• The full OrchestratorMcpService suite (60 tests), the picker browser tests and the mobile model-option tests pass on the tip.
• The UI is the same code exercised on https://git.cafe/pingdotgg/t3code/pulls/29833 in an isolated web client: a selected custom model stayed labelled, with its reasoning control and Hidden badge, after hiding and reloading, and it was absent from the picker and search. No paid provider turns were run.
• The native mobile app and the Electron shell were not exercised by hand. Mobile logic is covered by focused tests and typechecking.

Screenshots

Before: custom models have no usable visibility switch.

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

Scope

Discussion: #29735. This extends the existing model-visibility control to custom models. It doesn't add grouping, presets or proxy-side filtering.

Rebuilt with Claude Opus 5.5 in Claude Code, from the implementation in https://git.cafe/pingdotgg/t3code/pulls/29833, which was written with GPT-6.1 Sol in Codex CLI.

Takeover verification

Merged current main with a merge commit (9b7f27f950), resolving the mobile scheduled-task import conflict by keeping the full model catalog lookup and main's header cleanup. The feature diff remains 28 files, +655/-212.

Blacksmith vp run check:changed github/main passes: format, lint, knip, typecheck, all 285 tests in 12 focused files, and React compiler checks. Two independent read-only reviews approved this head with no findings. Existing bot findings were already fixed or withdrawn.

In an isolated web client, hiding the custom model persisted across reload, removed it from the composer picker, and showing it restored the picker choice. No paid provider turns were run. Native mobile and the Electron shell were not manually exercised.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Custom models can now be hidden without deletion, while automatic defaults and new-work fallbacks skip them. Human review must confirm the changed default-selection behavior, including choosing another model or requiring a visible model before continuing.

Walkthrough

Hidden-model preferences now apply to built-in and custom model catalogs, selection and fallback resolution, and defaults across web, mobile, and server flows. Saved hidden selections remain identifiable in interfaces. MCP listing and target resolution also account for hidden models.

Changes: Hidden model visibility

Layer / File(s)	Summary
Catalog and selection rules 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	Web and mobile catalogs mark hidden entries, while selectable options and default resolution account for visibility. Tests cover hidden built-in and custom models, visible fallbacks, and selections that retain hidden-model metadata.
Visibility controls and model defaults apps/web/src/components/settings/ProviderModelsSection.tsx, apps/web/src/components/settings/scheduledTasksSettings.logic.ts, apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts, docs/user/project-settings.md	Provider settings apply visibility controls to built-in and custom models. Project and scheduled-task defaults account for hidden models. The documentation describes visibility settings and their effect on existing selections.
Web picker and composer selection flows apps/web/src/components/chat/*, apps/web/src/composerDraftStore.ts, apps/web/src/composerDraftStore.test.ts, apps/web/src/hooks/useHandleNewThread.ts, apps/web/src/hooks/useHandleNewThread.test.ts	Web pickers exclude hidden models and label saved hidden selections. Composer and sticky-selection flows apply destination preferences. Sending prompts for settings when no model is selected.
Mobile thread and scheduled-task selections apps/mobile/src/components/ComposerModelControl.tsx, apps/mobile/src/features/settings/*, apps/mobile/src/features/threads/*	Mobile labels identify hidden saved selections. Thread and scheduled-task flows use the shared selected-model resolver. The thread settings catalog ignores presses on hidden models.
MCP model listing and target resolution apps/server/src/mcp/OrchestratorMcpService.ts, apps/server/src/mcp/OrchestratorMcpService.test.ts	MCP listings omit hidden models. Target resolution skips candidates without visible fallback models and returns model_unavailable when no eligible model is available.

Merge Risk: Moderate · up to 9b7f2

Hiding every model can prevent users from editing queued messages or resuming a held queue. An unrelated settings-read failure can also block some inherited-model requests. Address these paths before merging.

Full details: Title check

Explanation

The title "feat(settings): hide custom models from pickers without deleting them" matches the main change in the changeset. The raw summary and PR objectives both describe extending the existing model-visibility control to custom models in Settings → Providers, and hiding them from pickers and automatic defaults without removing them. The title uses a conventional commit format, is one sentence, and avoids vague terms. It is slightly broad because the changeset also spans defaults, sticky selection, mobile, and server MCP discovery, but it names the primary change.

Full details: Description check

Explanation

The description is mostly complete. It explains the problem, implementation, scope, behavior, verification results, limitations, and includes before/after UI evidence. It does not use the template headings exactly and does not include an explicit maintainer approval comment, but the linked discussion and scope explanation provide sufficient context.

Filter hidden fallback models before automatic selection.

464-464: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Filter hidden fallback models before automatic selection.

resolveNewThreadModelSelection does not check model visibility for fallbackSelection. When the default provider is usage-limited, a hidden fallback model can become the new task selection. Apply the same requireVisible filter that sticky selection already uses. A hidden fallback then resolves to null, and the resolver keeps the default selection. Explicit draft selections are unchanged because the resolver returns early when explicitSelection is set.

Suggested fix

-    fallbackSelection: selectedEnvironmentServerConfig?.settings.fallbackModelSelection ?? null,
+    fallbackSelection: resolveDefaultableModelSelection(
+      selectedEnvironmentServerConfig,
+      selectedEnvironmentServerConfig?.settings.fallbackModelSelection ?? null,
+      selectedProject?.id ?? null,
+      { requireVisible: true },
+    ),

514-519: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep runtime choices restricted for hidden saved models.

When the saved model is hidden, props.providerGroups omits it, so displayedModel is null. The runtime picker then offers every mode in RUNTIME_MODE_CHOICES, including modes the provider does not advertise.

Resolve the saved option from the full catalog when no visible option matches:

Suggested fix

   const displayedModel =
     pendingModel ??
     props.providerGroups.flatMap((group) => group.models).find((option) => isApplied(option)) ??
+    getSelectedModelOption(config, props.selectedModel, props.projectId) ??
     null;

Update the displayedModel resolution so that when neither pendingModel nor a
visible applied option matches, it reuses the selected model option from the
full catalog. Preserve the current precedence and ensure runtimeModeChoices
continues to derive supported modes from that resolved option, keeping hidden
saved models restricted to modes their provider advertises.

On CodeRabbit's follow-up review:

• Runtime choices for a hidden saved model (mobile thread settings): fixed in ca802aa, the catalog-lookup commit. When no visible option matches, the sheet now falls back to the saved selection's option from the full catalog, so runtime modes stay limited to what the provider supports.
• Hidden rate-limit fallback in mobile new tasks: intentional, same reasoning as the web thread. fallbackModelSelection is configured explicitly, and this PR keeps explicit configuration as is. Hiding only affects discovery and automatic suggestions.

Keep queued actions available without a selected model.

When selectedModel is empty, providerSendBlockReason disables the resume control through sendDisabledReason. The held-queue branch of useComposerResume only calls resumeThreadQueue and does not need a new model. Exempt held-queue resumption and queued-message editing from the model requirement, while keeping it for actions that start a new turn.

Queued editing also needs to bypass the separate providerAvailable guard in useComposerSend; that guard currently returns before queuedRunEdit.saveEdit(...) runs.
