Model variant (thinking effort) selector missing in V2 layout

[xohmai]

Description

When the "New layout and designs" setting is enabled, the model variant/thinking effort selector is not rendered in the composer UI. It only appears in the legacy layout.

In packages/app/src/components/prompt-input.tsx, the V2 layout branch (, line ~1457) renders ComposerAgentControl and ComposerModelControl in the bottom control bar but omits the variant that exists in the legacy branch (lines 1891-1919). The control was simply not migrated. Plugins None OpenCode version 1.15.13 Steps to reproduce Enable "New layout and designs" in Settings > General Select a model that supports variants (e.g., a reasoning model with low/high/xhigh effort levels) Look at the composer bottom bar — no variant selector is visible Disable "New layout and designs" — the variant selector reappears Screenshot and/or share link No response Operating System No response Terminal No response

This issue might be a duplicate of existing issues. Please check:

• V2 prompt input hides model reasoning selector #29051: V2 prompt input hides model reasoning selector — same root cause (variant selector not rendered in v2 prompt input layout)
• Desktop redesign hides model effort selector #29595: Desktop redesign hides model effort selector — same symptom (effort/variant selector missing after UI redesign)

Please review those issues and consider closing this one if it's already covered. If this tracks a distinct aspect not covered by those issues, please clarify the difference.

Completed by #30646 (feat(app): v2 thinking level selector), merged as 55bafa29d4b. The current V2 composer renders the variant/thinking selector for models with variants. Closing as completed.
