Anthropic’s October 22 release notes announce Claude Models on Google Cloud (Anthropic managed), with Google Cloud IAM access controls and Marketplace billing.
The service is operated by Anthropic and also supports fast mode for Claude Opus 5.5. Setup creates a separate Anthropic organization for the Google Cloud project; existing API keys, workspaces and stored resources do not automatically transfer. Teams should verify IAM roles, feature support and resource migration before switching traffic. The launch date comes from the official release notes; an exact publication time is not provided.
