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","keyPoints":["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"],"whyItMatters":"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.","category":{"slug":"enterprise","name":"Enterprise & Industry","url":"https://digestai.news/category/enterprise"},"entities":{"companies":["Google","Antigravity","Google AI Plus","Google AI Pro","Google AI Ultra","Enterprise"],"models":["Claude Sonnet 4.6","Claude Opus 4.6","GPT-OSS-120b","Gemini 3.8 Flash","Claude Sonnet 5.5","Claude Opus 5.5"],"people":[]},"firstPublishedAt":"2026-11-02T13:26:00Z","updatedAt":"2026-11-02T13:26:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"What to review when changing Antigravity models: Scheduled end of Claude 4.6 and GPT-OSS, and continuous AI operations","url":"https://note.com/ai_sokuho/n/n404adf2eb9e4?hl=en","publishedAt":"2026-11-02T13:26:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"AI Coding Models Race Toward October Efficiency","url":"https://digestai.news/thread/anthropic-releases-free-crash-course-on-building-ai-agents-with-opus-5-5","storyCount":7},"cite":{"text":"Digest AI, \"Google discontinues Claude 4.6 and GPT-OSS-120b in Antigravity on November 2\", 2 November 2026, https://digestai.news/story/google-discontinues-claude-4-6-and-gpt-oss-120b-in-antigravity-on-nove","publisher":"Digest AI","title":"Google discontinues Claude 4.6 and GPT-OSS-120b in Antigravity on November 2","datePublished":"2026-11-02T13:26:00Z","url":"https://digestai.news/story/google-discontinues-claude-4-6-and-gpt-oss-120b-in-antigravity-on-nove"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
