## Summary

Google’s Antigravity platform will remove **Claude Sonnet 4.6**, **Claude Opus 4.6**, and **GPT-OSS-120b** on **November 2, 2026**, according to official documentation. The exact end time and user rollout timeline remain unclear. These models are not being replaced by free-tier alternatives like **Gemini 3.8 Flash**, which is available in the free plan and **Google AI Plus**. Instead, **Claude Sonnet 5.5** and **Opus 5.5** will require **Google AI Pro contracts**, **Google AI Ultra**, or **Enterprise plans**, with no trial access. Users must verify their contract terms, as free trials and paid contracts have different usage conditions, even under the same

## Key points

- Claude 4.6 (Sonnet/Opus) and GPT-OSS-120b end on November 2, 2026, with no confirmed cutoff time or user rollout date
- Gemini 3.8 Flash replaces free-tier models, but Claude 5.5 requires paid Pro/Enterprise contracts—no trial access
- Google warns against relying on past model performance; users must test new models with real tasks and verify handover memos

## Why it matters

Teams using Antigravity for code, design, or testing must audit workflows now to avoid disruptions. The shift forces a review of contracts, operational costs (time spent correcting outputs), and migration risks—especially for projects tied to deprecated models.
