OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei are engaged in a decade-long rivalry. The feud originated from Amodei’s departure over OpenAI’s strategic direction and safety protocols.

Amodei reportedly compared the legal battle between Altman and Elon Musk to the conflict between Hitler and Stalin. Reports indicate Amodei also likened OpenAI to tobacco companies selling harmful products.

The CEOs avoided a handshake at a tech summit to signal their public animosity. Anthropic released a Super Bowl advertisement that implicitly criticized the OpenAI business model.
