Google's coding tool Antigravity has added Claude Opus 5.5 and Sonnet 5.5 (thinking) to its model list. According to Google's documentation, they are available to Google AI Pro (non-trial) and Google AI Ultra subscribers. Free, Google AI Plus, Enterprise and trial Pro accounts are left out. An alert from @Claudeupdates11 drew 11,000 likes.
The same documentation says Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120B will be removed on November 2. Since free and Plus users can only reach Claude through the 4.6 models today, they may lose Claude in Antigravity after that date. Some Pro users posted that they still do not see 5.5 in the list. Others speculated that the change signals Gemini 4 Argon is close.
