For deployments hosted on Azure, prompts and completions remain within Azure. Only usage metadata and content flagged by Anthropic's safety systems egress to Anthropic. Anthropic continues to provide its safety and data commitments.

158 * **Region scope:** Select Global, or for models hosted on Azure, Data Zone. Selecting Data Zone creates a US Data Zone Standard deployment, which keeps inference within the United States and is equivalent to setting [`inference_geo: "us"`](https://platform.claude.com/docs/en/manage-claude/data-residency#inference-geo) on the Claude API.
