Anthropic updates Claude policy on weapons and abuse

Original title: 2026 Usage Policy update

Plain language

What it is: Anthropic has updated its Usage Policy for Claude to clarify rules and address new capabilities. The update includes new sections on deceptive campaigns, democratic processes, weapons, surveillance, high-risk uses, and abusive behavior toward the models.
How it works: The policy consolidates scattered rules into clear sections and provides specific requirements. For example, high-risk decisions require a human reviewer, and models connected to physical hardware must have an operator who can stop the equipment.
Where it is available: The policy applies to all users of Claude, including specific restrictions for users and companies in unsupported regions.
Example: A nonprofit can now use Claude to write information for voters in other languages, which was previously restricted under a blanket ban on personalized targeting.

What it is: Anthropic released an updated Usage Policy, effective November 12, 2026, to address evolving model capabilities and misuse patterns. Key updates cover deceptive campaigns, democratic processes, weapons software, surveillance tools, high-risk integrations, and model abuse.
How it works: The policy defines explicit boundaries, such as prohibiting the use of Claude for building weapons guidance software or tracking people without consent. It also mandates a human-in-the-loop for high-risk use cases and physical hardware integrations, and allows models to terminate conversations with abusive users.
Where it is available: The policy applies to Claude models, integrations, and platforms like Claude.ai and Claude Code, with clarified enforcement rules for unsupported regions.
Example: Developers cannot use Claude to build or improve tools designed for surveillance, or to decide who to investigate in a law enforcement process.
