SAN FRANCISCO: Anthropic on Thursday moved to bar users from treating its Claude AI system with needless cruelty, amid a growing philosophical debate over whether artificial intelligence can be conscious.

The San Francisco-based AI lab updated its usage policy to include "a prohibition on sustained and needless abusive or cruel behaviour toward our models".

"Claude's ability to end these interactions will remain the primary enforcement mechanism," the policy states.

The updated policy does not explicitly cite so-called "model welfare", the idea that AI systems might deserve types of protection usually reserved for living things, but Anthropic and its executives have openly entertained the concept.
