Anthropic researcher resigns, warning that AI companies are "gambling with our lives"

Jacob Coxon, who has spent the past three years working on research into how to train AI models, first at OpenAI and more recently at Anthropic, announced his departure in a lengthy social media post on Monday.

"Neither company is acting responsibly," he wrote. At OpenAI, he said, staff "have not deeply internalized the civilizational stakes." At Anthropic, he said staff understand the risks well but are "locked in a race to get there first," based on the theory that no rival company will act as responsibly as they will, so they have the best chance of figuring out how to build superpowerful AI safely.
