Dario Amodei QUIT OpenAI to Build a Safer Rival

He was the safety chief at the world's hottest AI lab. Then he left to build a rival.

Dario Amodei trained as a physicist, earning a doctorate before deciding AI was the real frontier.

He worked on deep-learning teams at Baidu, then Google, building the networks behind modern AI.

At OpenAI he rose to VP of research, helping create the systems that led to GPT-3.

But he grew convinced the technology was racing ahead faster than anyone could make it safe.

In 2021 he left, and his sister Daniela and several senior researchers walked out too.

Together they founded Anthropic, built on one idea: make AI safe before it can do harm.

They named their AI Claude and pitched honesty and caution as features, not weaknesses.

Investors poured in billions, and Claude became one of the most used AI assistants on Earth.

The physicist who feared the future had built a giant by trying to slow it down.
