Anthropic Says Claude Helped Write Its New Constitution

Anthropic says its Claude AI system played a significant role in developing the principles that guide its behaviour, marking a further step in the company’s approach to AI alignment. The work builds on Anthropic’s broader Constitutional AI framework, in which a written constitution is used to define the values and behavioural principles that the model should follow.

Anthropic published its latest constitution in January 2026 as a detailed document describing how Claude should behave and the values the company wants the system to embody. The document is substantially more extensive than earlier versions and is intended to serve as a foundational guide for Claude rather than simply a list of isolated rules.

The development is significant because it gives an AI system a more active role in a process traditionally handled primarily by humans. Rather than relying only on engineers and policy researchers to specify every principle, Anthropic’s approach allows Claude to assist with evaluating and refining ideas while human researchers remain responsible for the overall direction and decisions.

Anthropic’s constitution covers issues including honesty, helpfulness, safety, human rights and how Claude should respond when different values come into conflict. The company describes the document as the final authority on its intended vision for Claude’s values and behaviour, making it an important component of the model’s alignment process.

The development also raises broader questions about who should determine the values of increasingly capable AI systems. Giving AI models a role in shaping their own behavioural guidelines could make alignment work more scalable, but it also makes human oversight especially important. Anthropic’s approach therefore represents not only a technical experiment, but also a wider debate over how society should decide what advanced AI systems should value and how they should behave.
