It was the tweet heard ‘round the world. Last week, a little-known Anthropic employee named Jacob Coxon announced that he was resigning from the company. “I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly,” he wrote. “The people building AI earnestly believe that it could kill us all by the end of the decade.” Coxon wasn’t the first employee to quit over similar fears. In 2024, William Saunders told a US Senate committee that he “resigned from OpenAI because I lost faith that by themselves they will make responsible decisions about AGI.” And in February, Mrinank Sharma wrote that he was leaving Anthropic because “the world is in peril” from AI and other risks, and he felt he couldn’t act with sufficient integrity at the company. Yet for whatever reason, it was Coxon’s message that broke through. His tweet has been viewed over 170 million times. He was interviewed on CNN , CBS , and Fox News . Lawmakers and cel

For the first time, an AI model was used to solve one of math’s most famous problems — a Millennium Problem . OpenAI announced that a swarm of 10,000 agents had produced a solution to a problem known as Navier-Stokes. Unlike those earlier AI milestones, however, no one was happy on Tuesday. Not even OpenAI. The night before OpenAI’s announcement, the NYU mathematician Tristan Buckmaster announced that he and collaborator Levent Alpöge had solved three problems closely related to Navier-Stokes. Alongside rough drafts of three papers — some 245 pages in total — Buckmaster released a statement excoriating OpenAI. “I had planned to say on announcing our work that the results are not the important thing. Rather the important thing is instead the significance that a mathematician and a
