Google Cloud adds Claude Opus 5.5 and Sonnet 5.5 to Google Antigravity
Overview
Google Cloud says Claude Opus 5.5 and Claude Sonnet 5.5 are now available in Google Antigravity for Google Cloud customers once an administrator enables them.
Opus 5.5 is built for complex work, and Sonnet 5.5 is a faster, lower-cost option in the model picker alongside Gemini 3.8 Flash and Gemini 4 Argon.
Third-party partner models do not draw from the pooled Gemini Enterprise Standard and Plus edition monthly token quota. Usage is instead billed pay-as-you-go through the customer's Google Cloud Billing account, so overages must be enabled. Customers must enable Claude models in Model Garden and accept the standard Anthropic terms.
