Unusual Path to AI
Daniela Amodei is not an engineer. She studied English literature and music, starting her career in global health and politics: she worked on a winning Congressional campaign in Pennsylvania and briefly ran communications for Congressman Matt Cartwright in Washington. In 2013 she joined Stripe as one of the first employees, and in 2018 OpenAI, where she managed the team during work on GPT-2 and rose to VP of Safety and Policy. In 2020 she left along with her brother Dario and a group of researchers who disagreed with the direction of the company under Sam Altman.
Anthropic: Safety as Product
As President of Anthropic, she runs the operational side of the company and the safety and compliance teams, while Dario leads research direction. She represents the company in conversations with regulators and corporate clients, and her public thesis is that safety should be a product feature, not a brake. Anthropic was valued at $965 billion in May 2026, and its Claude models, including Fable 5.1, compete for the top of the AI model rankings. In February 2026 the company refused the Pentagon’s request to remove Claude’s ban on use for mass surveillance, as I write in her brother’s biography.
