Anthropic’s AI Safety Head Just Resigned. He Says ‘The World Is In Peril’
Anthropic‘s AI safety lead Mrinank Sharma has resigned, saying his final day at the company was on Monday, according to a letter he posted on X. In the note, Sharma reflected on his work at the artificial-intelligence startup and his reasons for stepping down.

The resignation comes at a time when AI companies are under growing scrutiny from regulators and researchers over safety, transparency, and the societal risks of increasingly powerful models.
Sharma said he joined Anthropic after completing his PhD, aiming to contribute to AI safety. He highlighted work on understanding AI sycophancy, developing defenses against AI-assisted bioterrorism, and helping build internal transparency mechanisms.
“I’ve achieved what I wanted to here,” he wrote, adding that he felt fortunate to contribute to early AI safety efforts at the company.
