Custom models exposed through a proxy are currently always shown in T3 Code's model pickers. Keeping every model available to the underlying providers shouldn't require showing every model in the UI—or deleting its configuration to hide it.

This lets custom models use the existing visibility switches in Settings → Providers, including Enable all / Disable all. It reuses the existing per-provider preferences, with no new settings or changed defaults.

Hidden custom models retain their definitions and can be shown again.
Hiding a configured custom model does not replace an existing composer or saved default selection. The current selection keeps its label and controls; after switching away, the hidden model disappears from the picker. Built-in fallback behavior is unchanged.
Web/desktop, mobile pickers, and MCP model discovery honor the same visibility preference.

Before / after

Before: custom models cannot be hidden	After: hidden without deleting the definition

Validation

Regression coverage for picker filtering, preserving selected hidden custom models, provider-instance isolation, mobile visibility, and MCP discovery.
vp run check:changed covers format, lint, knip, affected typechecks, adjacent tests, and React compiler checks.
Browser-tested with isolated dev state: hide, reload, picker omission, bulk disable/enable, and show again. Also verified that hiding the selected custom model preserves its label, then switching away removes it from search. No paid agent turns were run. Native mobile and Electron were not manually exercised.

Implemented with GPT-6.1 Sol via Codex CLI. Reviewed with Claude Opus 5.5 (medium) via Claude Code; the selection-display finding was fixed in a follow-up.

🟠 High src/modelSelection.ts:135

Hiding a custom model that is already selected silently substitutes another model in the composer, even when the model still exists in the catalog and preserveUnavailableSelection is true. This filter also feeds resolveAppModelSelectionForInstance, so keep picker visibility filtering separate from validation of existing selections against configured models.

Fixed in 56c92b577. Picker options remain visibility-filtered, while selection validation uses the configured custom-model catalog. Hidden custom selections are retained in the composer and saved defaults; built-in fallback behavior is unchanged. Updated the existing regression table to verify both resolution modes and confirm the hidden custom model remains absent from picker options. The regression failed before the fix; vp run check:changed now passes (136 tests and 8 React compiler cases).

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — Custom models can be hidden per provider without deleting their configuration, consistently across pickers and MCP discovery. The reported selected-model substitution remains blocked by the separate correctness gate; no additional material risk requires human judgment.

Needs human approval because:

Walkthrough

Hidden-model preferences now apply to custom models in provider settings, web and mobile model selection, and MCP capability listings. Tests cover filtering, fallback selection, and restored visibility. Documentation describes provider-instance visibility and retained custom-model configuration.

Changes: Custom model visibility

Layer / File(s)	Summary
Manage custom model visibility `apps/web/src/components/settings/ProviderModelsSection.tsx`, `docs/user/project-settings.md`	Provider settings include custom models in hidden grouping, counts, bulk controls, and visibility switches. Removing a custom model also removes its hidden preference. Documentation describes instance-scoped visibility and retained configuration.
Filter hidden models in selection `apps/web/src/modelSelection.ts`, `apps/web/src/modelSelection.test.ts`, `apps/mobile/src/lib/modelOptions.ts`, `apps/mobile/src/lib/modelOptions.test.ts`	Web and mobile model selection filter hidden custom models, with a selected custom model retained where applicable. Tests cover filtering, fallback behavior, and restored visibility after preferences are cleared.
Filter hidden models from MCP listings `apps/server/src/mcp/OrchestratorMcpService.ts`, `apps/server/src/mcp/OrchestratorMcpService.test.ts`	MCP capability listings exclude hidden custom models. The test fixture hides a custom OpenCode model alongside a built-in model.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Keep hidden custom selections resolvable for existing threads.

Hiding a custom model removes it from the list that resolveAppModelSelectionForInstance uses. An existing thread whose selection names that hidden model does not keep it. The preserveUnavailableSelection flag from deriveEffectiveComposerModelState does not restore it. The selection falls back to the default or first option, and the next turn can use that model.

The PR states that explicit selections remain valid. Hiding should control only picker visibility. Keep the picker-filtered list separate from the list used to resolve an existing selection. The default-selection path (resolveEffectiveDefaultModelSelection) also uses preserveUnavailableSelection: true, so it has the same exposure.

Built-in hidden models already follow this fallback. This change extends that behavior to custom models, which previously resolved.

✅ Addressed in commit 56c92b5

Ssamaluk6d ago

Fixed in 56c92b577, addressing the same selected-model regression identified by Macroscope. Configured custom-model selection validation is now independent of picker visibility, including the effective-default path; hidden built-in fallback semantics are unchanged. The updated regression fails without the fix, and vp run check:changed passes.

CcoderabbitaiBot6d ago

@samaluk Thanks. The supplied code confirms that resolveConfiguredAppModelSelection preserves configured hidden custom-model selections independently of picker visibility. resolveEffectiveDefaultModelSelection uses that resolution path, while hidden built-in models remain subject to fallback. This addresses the finding.

5	Learning: In `apps/web/src/modelSelection.test.ts`, tests comparing `resolveEffectiveDefaultModelSelection` with project-default resolution in `deriveEffectiveComposerModelState` should pass `threadModelSelection: null` and the stored default as `projectModelSelection`. In `apps/web/src/composerDraftStore.ts`, a null thread selection makes `preserveThreadModel` false, so an unavailable, non-hidden OpenCode or Antigravity project-default model falls back instead of being preserved.

fix(web): preserve hidden custom model selections56c92b5

Exercise the hidden custom selection through the caller paths.
This test stops at resolveAppModelSelectionForInstance, so a regression in the composer or project-default caller could replace openai/gpt-5.5 without failing it. The existing caller-level parity test covers only a hidden built-in model, while configured custom models use a separate branch. Add composer and effective-default assertions to this parameterized case.

Build the selected option after the automatic fallback resolves.

modelOptions hides a custom model unless it matches the draft, project-default, or sticky selection. The server fallback can be the resolved selectedModel without matching those selections. In that case, selectedModelOption is null, and the new-task settings sheet loses that model's capabilities.

Closing this implementation in favor of a clean replacement with an explicit product contract: hiding a custom model changes discovery, not saved selections or execution. The replacement will separate selected-model metadata from visible choices, preserve existing references, and skip hidden models for automatic suggestions. The proposal remains open in #29735; I will link the replacement PR here.

Ssamaluk6d ago

Replaced by #29833. The new PR separates selected-model metadata from visible choices and spells out what happens to saved threads/drafts, defaults, fallbacks, scheduled tasks, agent references and automatic suggestions. Before/after screenshots are in its description. Discussion #29735 remains open and has been updated for this intent.
