You can also run the update script locally using Bun:

bun install opencode-ai
bun run scripts/update-json.ts

A cross-platform CLI that syncs model definitions directly into VS Code's chatLanguageModels.json, with optional cron / scheduled task support.

1. Download the latest binary from Releases
2. Run the sync:

# One-time sync (Windows: opencode-auto-update-windows-x64.exe)
./opencode-auto-update --sync

# Sync a specific provider + source
./opencode-auto-update --sync --provider "OpenCode Go" --source go

Or build from source:

bun install
bun run build       # → dist/opencode-auto-update (or .exe on Windows)

# Run daily at 2 AM
./dist/opencode-auto-update --install

# Run every hour
./dist/opencode-auto-update --install --schedule hourly

# Run weekly
./dist/opencode-auto-update --install --schedule weekly

# Remove the schedule
./dist/opencode-auto-update --uninstall
