Anthropic updates usage policy, banning sustained abuse of Claude

Anthropic revised its usage policy for the first time in over a year, adding rules on election interference, weapons development, surveillance, and health and financial uses. It also prohibits sustained and needless abusive or cruel behavior toward Claude, with ending conversations remaining the primary enforcement mechanism.

Why it matters: The abuse rule extends Anthropic's model-welfare research into enforceable policy, an unusual stance among major labs. The tighter limits on election, weapons and surveillance uses show policy catching up with agentic capabilities that make such misuse more practical.
