feat(web): OpenCode's model picker folds each vendor into a collapsible section - #30801
With several providers connected through OpenCode (a subscription, an API key, the free Zen models), the model picker lists every model from every vendor in one interleaved list. Finding one vendor's models means scrolling past all the others.
The server already labels each OpenCode model with its upstream vendor (subProvider). The picker now uses that label: when a provider tab spans two or more vendors, its models fold into collapsible vendor sections sorted by name. A tab with a single vendor still renders as a plain list.
The section holding the model the picker opened with starts open, otherwise the first section. Picking or starring a model in the docked picker does not open or collapse other sections; only clicking a header does.
Favorites and models without a vendor stay above the sections. The Favorites tab and search stay flat, so search still finds models in collapsed sections.
Headers are list items, so the keyboard and Enter toggle them the same way as the existing "Show more" row, which still trails the list. Number-key shortcuts count only visible models.
Rows inside a section drop the vendor label, since the header already names it.
Open sections last for one picker session. Nothing is persisted, and there are no server, contract, or mobile changes. Mobile keeps showing the vendor as a row subtitle.
This revisits #8072, which was closed for its size across server, web, and mobile. This version is web and desktop only (+283 lines, 124 of them tests) and builds on the subProvider labels that #7562 kept. I have no maintainer approval of the direction yet: see this comment on #8072.
Before
After, on open
After, second section expanded
After, search
The screenshots render ProviderModelPicker in a browser test with a sample four-vendor OpenCode catalog, not a running app with real providers.
Proof: vp run check:changed passes. The new case in ProviderModelPicker.browser.test.tsx fails on main (the second vendor's models are visible on open). It also covers a docked pick from a second section leaving the first section open. modelPickerVendorSections.test.ts covers sort order, pinned models, the two-vendor minimum, and a starred opening model keeping its section open. Not checked: a live OpenCode server with several connected providers, and the Electron desktop shell.
Implemented with Claude Opus 5.5 in T3 Code, reviewed by Claude Opus 5.5 and GPT-6.1 Sol.
Takeover verification on 1b6c5b0e75: blacksmith vp run check:changed passes, including the focused browser tests. The real app was also exercised with the live OpenCode catalog for section toggles, collapsed search, clearing search, provider switching, and model selection.
Macroscope's review found this PR requires human approval — The picker now hides most vendor groups by default, opening the current model's vendor or the first alphabetical vendor. Human review must confirm this change to initial model visibility and discoverability.

The model picker groups eligible models into vendor sections outside search and Favorites views. Users can expand or collapse sections. The picker includes vendor headers in list sizing and keyboard navigation, and section rows hide repeated sub-provider labels.

Summary
Vendor grouping and keys apps/web/src/components/chat/modelPickerVendorSections.ts, apps/web/src/components/chat/modelPickerKeys.ts, apps/web/src/components/chat/modelPickerVendorSections.test.ts
The grouping helper sorts vendor sections, separates pinned models, and selects a default vendor. The key helper encodes provider instance IDs and vendor names. Tests cover grouping, pinning, and default selection.
Picker grouping and expansion apps/web/src/components/chat/ModelPickerContent.tsx
The picker derives the initially expanded vendor from the opening model and favorites state, applies section overrides, and builds ordered list keys and visible models. Height estimation accounts for tabs with multiple vendors.
Section interaction and rendering apps/web/src/components/chat/ModelPickerContent.tsx, apps/web/src/components/chat/ModelListRow.tsx, apps/web/src/components/chat/ProviderModelPicker.browser.test.tsx
Vendor headers toggle through selection or Enter and show the vendor name, model count, and expansion state. Rows within vendor sections omit the sub-provider label. The browser test covers search, expansion, and model selection.

Merge Risk: Minimal · up to 1b6c5
The model picker now groups OpenCode models into collapsible vendor sections. No actionable merge-blocking risk remains. The Electron, mobile, and remote modes were not exercised, but that is normal validation uncertainty.

Explanation
The title names the main change: OpenCode's model picker groups each vendor into a collapsible section. It matches the changeset (vendor sections in ModelPickerContent, groupModelPickerVendors, and the vendor section key). The title is in conventional commit form and is specific enough for a teammate scanning history.
Full details: Description check
Explanation
The description follows the template's main parts. It states the problem (an interleaved, unsorted list of models across vendors) and the change (vendor sections built from the subProvider label). It links the prior PR and gives a scope note. It includes verification: the tests added, the command run, the checks not covered, and before/after screenshots. The template asks for a conventional commit title and an explicit maintainer approval link. The author says the direction is not yet maintainer-approved, and the linked comment is on the closed PR #8072, so the Scope and approval section does not meet the template's requirement. The Problem heading has no explicit reproduction steps beyond the description of the interleaved list. The agent attribution line is present.
Resolution
Add explicit maintainer approval for the direction and scope. Link the triaged issue or the discussion with the approval comment, or explain why this change qualifies as a focused fix without prior approval. Confirm the Scope and approval section cites that approval, since the current link is a comment on closed PR #8072 and the author states no approval exists yet. Optionally add reproduction steps for the Problem section. The Verification section already covers tests and screenshots.

The current browser test covers header expansion only through openAiSection.click(). Add keyboard navigation to the OpenAI header, press Enter, and assert that OpenAI expands while Claude Sonnet remains selected. This exercises the changed onKeyDown branch and detects both a failed toggle and accidental model selection.

merged current main without rebasing and preserved both picker browser tests. addressed the two new review findings: header sizing now uses opening favorites, and legacy models cannot change section eligibility when starred. pinned rows still follow current favorites. kept the earlier takeover fixes for opening defaults, accessible vendor names, and fully favorited vendors.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Replace the forEach callback with a simple loop in the height calculation.
Line 603 uses vendors.forEach(() => addRow(instanceId)) only to repeat a call. This hides the intent and reads like a mistake. A plain loop over vendors.size states the intent directly.

Simplify the vendor-header height calculation.
vendors.forEach(() => addRow(instanceId)) uses forEach only to repeat a call vendors.size times. It also uses a side-effecting callback in a conditional expression. A plain loop states the intent more clearly.

Review comments at @apps/web/src/components/chat/ModelPickerContent.tsx:
- Line 610: Update the height-estimation logic near the sub-provider model check
to count vendor headers using the same opening-state eligibility as
vendorGroups, rather than the filtered vendorsByTab state. Keep the estimated
header count aligned with the headers vendorGroups retains when favorites
change.
- Line 716: Snapshot legacy-model membership when the picker opens, alongside
favoritesAtOpen, and use that snapshot to determine vendor-section eligibility
so starring or unstarring a model does not change flat-versus-sectioned layout
during the session. Keep current favorites for pinned rows, and update the
legacySection/currentModels flow without changing that behavior.

approval section instead of only noting it in the intro. Also add the model and
harness used at the end, as the template requests. The author's note says they
used Claude Opus 5.5 and GPT-6.1 Sol, so the agent line is present but should
