A researcher says he has resigned from one of the major AI companies and is now sounding a dramatic warning about the future. He alleges that both Anthropic and OpenAI are behaving irresponsibly by aiming for a “self-improving superintelligence” that he says has a real chance of wiping humanity off the face of the Earth.
Jacob Coxon, 27, is an AI researcher and math graduate who has worked in training new AI models at both OpenAI and Anthropic. Newsweek confirms he was a member of the OpenAI technical staff from 2023 to 2026, worked on the GPT-4o model, and joined Anthropic earlier this year to train their models.
