Jacob Coxon

Former AI Researcher, Anthropic and OpenAI

Jacob Coxon is a British AI researcher specialising in the pretraining of frontier AI models. He spent roughly three years working across OpenAI and Anthropic, including research associated with the development of increasingly capable foundation models. In September 2026, Coxon resigned from Anthropic and left frontier AI development, publicly arguing that leading AI laboratories were moving too quickly towards self-improving systems without adequate safeguards. His intervention rapidly made him a prominent new voice in the debate around AI alignment, superintelligence and existential risk.
