v3.0.1
Current Antigravity models
- Add Claude Opus 5.5 and Sonnet 5.5 with low, medium and high adaptive effort, a 1,000,000-token context and 128,000-token output limit.
- Retire Claude 4.6 routes. Requests refuse locally instead of silently switching models. Update saved selections to
google/antigravity-claude-opus-5-5orgoogle/antigravity-claude-sonnet-5-5. - Refresh model metadata and client identity from AGY CLI 1.3.3. Preserve server-offered Gemini 3.5 Flash and Gemini 3.1 Flash Image, even though they are absent from the CLI picker.
- Use native Claude adaptive-thinking fields and preserve explicit output caps, including warmups.
Windows account migration
- Fix
EPERM: operation not permitted, fsyncby opening regular files with the write access Windows requires for flushing. POSIX behavior and ownership checks stay unchanged. - A failed 3.0.0 attempt can leave an unchanged legacy pool and an abandoned backup generation. Keep those files; 3.0.1 migrates into a fresh active generation without adopting or modifying the abandoned backup.
Stop every OpenCode, OpenChamber, Pi and other Antigravity account-writing process before migrating:
npx @cortexkit/opencode-antigravity-auth@3.0.1 migrate --offlineRestart only after exit code 0 and Migration completed: generation … is active. If migration fails, keep hosts stopped and preserve the error and migration files. Already-active 3.0.0 stores do not need migration again.
Verification scope
The current server catalog and both low-effort Claude request fields were captured. Medium/high effort wire behavior, continuation/cascade metadata and other unexercised tool/stream cases are not claimed as complete AGY 1.3.3 wire-parity verification.
