Anthropic has published a constitution for its AI model, Claude, detailing the values and behaviors it should embody. This document serves as a guiding framework for Claude's training and decision-making processes, focusing on safety, ethics, and helpfulness.

• Anthropic replaced Claude's old list of standalone principles with a constitution that explains the reasoning behind behaviors, not just rules to follow
• Claude is instructed to prioritize being safe, then ethical, then compliant with Anthropic's guidelines, then genuinely helpful, in that order when conflicts arise
• The document is released under CC0 1.0, so anyone can use it freely
• Anthropic uses the constitution to generate synthetic training data that shapes Claude's judgment during actual training stages
