According to Anthropic (@AnthropicAI), the company has released the full constitution governing all its mainline AI models under a Creative Commons CC0 1.0 license, allowing developers and organizations to freely build upon and adapt the framework (source: https://twitter.com/AnthropicAI/status/2014005815376568780). This move enables broader adoption and customization of responsible AI principles, providing a transparent foundation for AI safety, ethics, and compliance. The open license lowers the barrier for businesses, startups, and research institutions to incorporate Anthropic's governance model into their own AI products, fostering industry-wide collaboration and accelerating the development of trustworthy AI systems (source: https://www.anthropic.com/constitution).
