Google models list outdated in TUI - missing Gemini 3 models

[movingChurch]

Problem

The TUI model selector shows an outdated Google models list. Newer models like gemini-3-flash-preview and gemini-3-pro-preview are missing.

Environment

• OpenCode version: 1.0.223
• OS: macOS
• Plugin: [email protected]

Expected Behavior

TUI should display all available Google models from models.dev, including:

• gemini-3-flash-preview
• gemini-3-pro-preview

Actual Behavior

TUI only shows older models (up to Gemini 2.5 variants with date suffixes like 05-06, 06-17).

Investigation

1. ~/.cache/opencode/models.json - Contains the latest models from models.dev, including Gemini 3 ✓
2. models.dev/api.json (live) - Contains gemini-3-flash-preview, gemini-3-pro-preview ✓
3. TUI model list - Missing Gemini 3 models ✗

It appears the models.dev JSON data is hardcoded into the binary at build time rather than being fetched/cached at runtime. The TUI does not seem to use the ~/.cache/opencode/models.json cache file.

Suggested Fix

Consider fetching/refreshing the models list from models.dev at runtime instead of bundling it at build time, or update the bundled data more frequently.
