Each year, Anthropic updates its Usage Policy in response to the evolving capabilities of our models, and the feedback we’ve received from our customers. We're publishing a new version of the policy today. In this post, we summarize the changes we’ve made.

Most of the updates in the latest version are intended to clarify existing rules. In the year since our last refresh, Claude has taken on longer, more independent work. This update provides new examples that show how our rules apply to Claude’s new capabilities. It draws on new patterns of misuse in influence operations, weapons development, and surveillance that we’ve observed in the past year (as we’ve documented in our latest threat intelligence report). We’ve also made updates to clarify our requirements for high-risk use cases in areas like health and finance, to add controls for when Claude is used to autonomously take physical actions, and to address abusive behavior toward our models.

The updated policy takes effect on November 12. The full Usage Policy and Supported Regions Policy can be found on their respective pages.
