Gemini Enterprise: Anthropic Claude Opus 5.5 and Claude Sonnet 5.5 in AI developer tools

Administrators can enable Anthropic Claude Opus 5.5 (claude-opus-5-5) and Anthropic Claude Sonnet 5.5 (claude-sonnet-5-5) for AI developer tools (Antigravity 2.0, Antigravity CLI, and Antigravity for IDEs). Third-party models are turned off by default:

• In-console Terms of Service consent flow: Administrators can opt in to Claude Opus 5.5 and Claude Sonnet 5.5 directly in Gemini Enterprise > Settings > AI developer tools > Antigravity authorized models in the Google Cloud console without a separate Anthropic account or onboarding. For more information, see Configure AI developer tools settings.
• Location availability: Third-party model inference is available in the global, us, and eu locations (in-country regions aren't supported). For a list of countries and regions that can access the model, see Anthropic's Supported countries and regions.
• Consumption billing: Third-party model usage is billed as consumption on your Cloud Billing account and counts toward your project's spend cap, which covers all models. Pay-as-you-go usage above quota must be turned on before you can enable a third-party model. For more information, see Configure pay-as-you-go usage above quota and the Cloud Billing SKUs for Anthropic Claude Opus 5.5 and Anthropic Claude Sonnet 5.5.
• Thinking levels: Developers sign in with their existing Gemini Enterprise license and select Claude Opus 5.5 or Claude Sonnet 5.5 in the model picker at a thinking level of Low, Medium, High, or Max (for example, Claude Opus 5.5 (High)). Medium is the default.
