Claude Models on Google Cloud (Anthropic managed) is GA: the full Claude Platform on your Google Cloud commitment

Claude Models on Google Cloud (Anthropic managed) lets you call the Anthropic-operated Claude API directly from a Google Cloud project. Authentication uses Google Cloud IAM roles such as roles/claude.user instead of API keys, and usage is billed on your Google Cloud Marketplace invoice and draws down existing Google Cloud commitments. Features like Managed Agents (beta), code execution, Agent Skills, the Files API, and prompt caching arrive the same day they do on the native Claude Platform; in Python you use the AnthropicGoogleCloud client.

pip install -U "anthropic[google_cloud]"

Until now, running Claude on Google Cloud meant the Google-operated Vertex offering, where new features often showed up late. Now teams can keep their Google Cloud commitments and IAM setup and still get the latest betas right away. Fast mode for Opus 5.5 is also GA here, with up to 2.5x faster outputVendor claim at $8 per million input tokens and $40 per million output tokens. Anthropic, not Google, is the data processor, though, so if you have strict data residency requirements or need Model Armor, stay on the Google-managed offering.
