Anthropic updates its Usage Policy, effective November 12, 2026

On October 8, 2026 Anthropic published a summary of updates to its Usage Policy, which it says take effect on November 12. The post says rules on deceptive activity that were previously spread across several sections are consolidated into a new section titled "Do Not Engage in Deceptive Campaigns or Artificial Activity", and that the elections section is renamed "Do Not Undermine Democratic Processes". It says the weapons prohibitions now explicitly include the software and components that make weapons work and actions such as arming drones and other autonomous vehicles, and it adds requirements for models connected to hardware that takes autonomous physical actions, including that a qualified operator can observe and stop the equipment. This item describes Anthropic's own policy for use of its models; it is not a government rule.1
