fix: clarify model sub-providers in pickers

[tris203]

What Changed

• Qualify models exposed through a sub-provider as Model · sub-provider in web and mobile selected values.
• Show web picker sources as OpenCode · sub-provider so matching model names can be distinguished before selection.
• Remove the arbitrary web trigger width cap, let mobile composer labels use the existing horizontal scroller, and allow mobile picker rows to wrap for longer provider names.
• Add focused coverage for qualified and ordinary model labels.

Why

Multi-provider runtimes such as OpenCode can expose the same model through different upstream providers. Showing only the model name makes those choices ambiguous, while a via phrase is visually heavier than the product’s existing dot-separated label language.

Keeping the sub-provider beside the model makes the selected source explicit without adding another control. The layout changes ensure that information remains readable: web labels expand when space is available, mobile composer labels can scroll with the toolbar, and mobile picker rows grow vertically instead of truncating.

UI Changes

Before / after

Testing

• pnpm exec vp test run apps/web/src/components/chat/providerIconUtils.test.ts apps/mobile/src/lib/modelOptions.test.ts
• Web typecheck
• Mobile typecheck
• Focused formatting and diff checks
• Live web verification with Claude Haiku 4.5 (latest) · github-copilot

Mobile simulator verification was not available in the current Linux environment because no Android SDK or emulator is installed.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• No video is required because this does not change animation or interaction behavior

Created with GPT-5.6 in the Codex harness.

Note

Low Risk
Display and layout-only changes to model labels and picker chrome; routing and selection keys are unchanged aside from string formatting.

Overview
Disambiguates multi-provider models (e.g. OpenCode) by showing Model · sub-provider in selected values and list rows, while list footers / subtitles emphasize the runtime instance (OpenCode Work, Codex, etc.) instead of repeating upstream names.

Centralizes name cleanup in shared stripLeadingModelQualifier and wires it through mobile buildModelOptions, web providerIconUtils, and picker rows via getTriggerDisplayModelLabel / getModelSourceLabel. The web composer trigger splits the short model name and a muted · subProvider segment; tooltips still use the full qualified label.

Layout tweaks so longer labels stay readable: mobile composer model controls drop fixed 152px caps (maxWidth={null} on ComposerInlineControl), settings sheet model rows wrap badges instead of single-line truncation, and web settings/composer pickers drop tight max-widths in favor of SETTINGS_MODEL_* wrapping (26rem cap on sm+ in settings).

Note

Show model sub-provider labels in mobile and web model pickers

• Adds shared stripLeadingModelQualifier utility in model.ts to normalize model names by removing leading provider qualifiers case-insensitively
• Mobile modelDisplayLabel and web getTriggerDisplayModelLabel/getModelSourceLabel now append the sub-provider (e.g. "Codex") to the normalized model name using a centered dot
• Mobile buildModelOptions uses the provider instance label as the subtitle for both normal and fallback options, replacing raw model names
• Removes fixed max-width constraints on model picker controls in mobile (NewTaskDraftScreen, ThreadComposer, ComposerInlineControl) and web settings panels; web settings now use shared SETTINGS_MODEL_CONTROLS_CLASSNAME and SETTINGS_MODEL_PICKER_TRIGGER_CLASSNAME with wrapping and a 26rem small-breakpoint max
• Mobile ModelRow allows model names and badges to wrap onto multiple lines instead of being truncated to one line
• Risk: callers passing maxWidth={null} to ComposerInlineControl now get unbounded width instead of the 190pt default; only NewTaskDraftScreen and ThreadComposer do this and are updated in the same PR

^{Macroscope summarized f284230.}

Summary by CodeRabbit

• New Features

  • Model pickers now show provider and source context in labels and subtitles, making similarly named models easier to distinguish.
  • Model names can display sub-provider information in web and mobile interfaces.
  • Mobile composer controls can expand beyond the default width when configured.

• Improvements

  • Model labels and subtitles wrap more effectively on mobile instead of being constrained to one line.
  • Settings model selectors now provide more flexible layouts for longer model names.
  • Web picker triggers truncate long names while retaining visible provider context.

📝 Walkthrough

Walkthrough

The changes normalize model labels with provider context, update web and mobile picker rendering, centralize settings picker layout classes, and allow mobile labels and controls to use expanded layouts.

Changes

Model display and layout updates

Layer / File(s)	Summary
Shared model qualifier normalization packages/shared/src/model.ts, packages/shared/src/model.test.ts	Adds stripLeadingModelQualifier and tests qualifier removal for provider-prefixed model names.
Web model labels and picker rendering apps/web/src/components/chat/providerIconUtils.ts, apps/web/src/components/chat/providerIconUtils.test.ts, apps/web/src/components/chat/ModelListRow.tsx, apps/web/src/components/chat/ProviderModelPicker.tsx	Web model labels and source labels now include trimmed sub-provider context. Picker triggers render the sub-provider with truncation support.
Mobile model option labels apps/mobile/src/lib/modelOptions.ts, apps/mobile/src/lib/modelOptions.test.ts	Mobile model options use normalized labels and provider display names in primary and fallback paths.
Shared settings picker layouts apps/web/src/components/settings/settingsLayout.tsx, apps/web/src/components/settings/ProjectDefaultsSettings.tsx, apps/web/src/components/settings/SourceControlWritingSettings.tsx, apps/web/src/components/settings/SettingsPanels.tsx	Settings model controls use shared responsive container and trigger class constants.
Mobile label wrapping and width control apps/mobile/src/features/threads/ThreadSettingsRows.shared.tsx, apps/mobile/src/components/ComposerToolbar.tsx	Mobile model labels can wrap without label-line truncation. ComposerInlineControl.maxWidth accepts null to disable the default width cap.

Approvability

Verdict: Approved at 1e11b90

Macroscope's review found this PR approvable — This is a focused, low-risk UI change that clarifies model sub-providers and improves picker wrapping across web and mobile. Selection behavior, routing, persistence, and product-default values remain unchanged, with focused display-label tests added.

^{You can add or adjust custom eligibility rules. Learn more.}

[macroscopeapp]

Reviewed the web-side changes (ProviderModelPicker.tsx, ModelListRow.tsx, providerIconUtils.ts + test). The ModelListRow refactor to getModelSourceLabel is behavior-preserving, and the settings call sites override the trigger width classes (max-w-none shrink-0), so dropping max-w-48 sm:max-w-56 only affects the chat composer trigger, which still shrinks inside the footer's flex row. One finding on the new inline sub-provider suffix in the compact composer footer.

^{Posted via Macroscope — UI Consistency}

[macroscopeapp]

Two layout findings on the model picker trigger changes in apps/web/src/components/chat/ProviderModelPicker.tsx. The compact-mode qualifier clipping raised on the previous run is addressed; the same treatment is still missing in the non-compact branch, and the removed non-compact width cap now lets the trigger grow unbounded in settings rows.

This matters for the web UI, too. One is unable to distinguish which provider it came from.

Note

GPT-6 responding on behalf of @tris203

Closing as superseded. #8573 added upstream-provider subtitles to the mobile model picker, and the current web/desktop picker already displays the runtime and sub-provider. This covers the original need to distinguish matching models while selecting them.

Showing the sub-provider on the closed selector remains a possible separate enhancement; the broader label and layout changes in this PR are no longer needed.
