A report examines Anthropic CEO Dario Amodei’s ideological background. His focus on AI safety is strongly influenced by the Effective Altruism and rationalism communities. Amodei and other former OpenAI employees founded Anthropic in 2021, with a safety-first approach as a core tenet of the company.

The profile describes significant past disputes between Amodei and OpenAI leaders, including CEO Sam Altman and co-founder Greg Brockman. They disagreed over the pace of AI development, commercialization and safety protocols. Those disagreements ultimately led Amodei to leave OpenAI.

The divide between the two AI labs reflects a broader industry debate over how to develop powerful artificial intelligence responsibly.
