Google Antigravity’s models documentation lists Claude Sonnet 5.5 (thinking) and Claude Opus 5.5 (thinking) as reasoning-model options.

Its plan table marks both unavailable on Free and Google AI Plus, available on Google AI Pro and Google AI Ultra, and unavailable on Enterprise. A footnote says Claude 5.5 is available on Google AI Pro only for non-trial subscriptions. The page says users select a reasoning model from the model selector beneath the conversation prompt box. It does not specify when these entries were added or independently establish rollout status for every account.
