The competition to build Artificial General Intelligence (AGI) isn’t just a race of code and chips; it is a deeply personal battle. The report traces the origins of the friction between OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei back to a shared San Francisco townhouse in 2016, where the foundational disagreements over AI safety and commercialization first began.

Key Revelations from the Feud:

• The Philosophical Divide: The conflict started with a debate over transparency. OpenAI President Greg Brockman believed the public should be informed about AI progress, while Amodei and his sister Daniela (Anthropic’s co-founder) argued that the technology was too dangerous to be handled with a traditional Silicon Valley “move fast and break things” mentality.
• Ethical Red Lines: A major breaking point occurred in 2017 when Brockman floated a plan to raise funds by selling AGI to world powers, including rivals like Russia and China. Amodei reportedly viewed this as “tantamount to treason,” sparking his first major consideration of leaving the company.
• The “Hitler vs. Stalin” Comparison: In recent internal communications, Dario Amodei has reportedly used extreme historical metaphors to describe the industry. He likened the legal battle between Sam Altman and Elon Musk to “Hitler versus Stalin” and characterized OpenAI’s pivot toward profit-seeking as being similar to “tobacco companies knowingly selling harmful products.”
• The Shouting Match: The final split in 2020 was punctuated by a dramatic confrontation. Altman accused the Amodei siblings of orchestrating negative peer reviews against him to the board. The meeting devolved into an angry shouting match, leading the Amodeis and several key researchers to walk out and form Anthropic shortly after.
• The Battle for the Pentagon: The feud has now reached the level of national security. While OpenAI recently signed a deal to perform classified work for the U.S. Defense Department, Anthropic has found itself barred from similar contracts under the Trump administration—a move that has led to lawsuits and further accusations of “mendacious” behavior by OpenAI leadership.

The Bigger Picture

This isn’t just “tech drama.” Because these two companies control the most advanced AI models in existence, their personal animosity is dictating global policy. Their disagreement over whether AI should be a “market-driven” product or a “public-interest” utility is currently shaping how the military, the government, and the general public will interact with the most transformative technology of the century.
