Jacob Coxon resigned from Anthropic over concerns about AI safety. He told Axios he left two months before any of his equity would vest. He had been at Anthropic four months, against a six-month vesting requirement. Coxon said he now has nothing to gain from raising Anthropic's valuation. He still holds equity in his previous employer, OpenAI. His resignation post on X has passed 115 million views, and said people building AI believe it could kill everyone. Coxon said he has not seen Anthropic compromise safety to beat rivals. He worries that racing pressure leads to cut corners and skipped oversight steps. He also described excessive fear of OpenAI and of China inside the industry. Models now routinely recognise when they are being tested, he said.
