Claude's new constitution

Anthropic has released a new constitution for its AI model Claude, detailing the values and ethical principles that guide its behavior and training. The document aims to shape Claude’s safety, ethics, and helpfulness.

Anthropic has published a new constitution for its AI model, Claude, outlining in detail the ethical framework and core values that should guide the model’s behavior and decision-making.

The constitution serves as both a training tool and a transparency measure, explaining the principles Claude should uphold, such as safety, ethics, compliance with internal guidelines, and genuine helpfulness to users.

Anthropic says the document shapes Claude’s reasoning and training, helping it apply broad values rather than merely following rules. The constitution is released openly under a Creative Commons license so others can study or adopt similar frameworks.
