Jacob Coxon, an AI pretraining researcher who previously worked at both OpenAI and Anthropic, has resigned from Anthropic over serious artificial intelligence safety concerns. Coxon publicly stated that key researchers building frontier AI models increasingly believe advanced self-improving systems could pose an existential threat to humanity before the end of the decade. His departure highlights growing internal friction within leading AI labs as the race to build autonomous, superintelligent systems accelerates. Coxon's warnings add to mounting calls from safety researchers urging AI companies and global regulators to prioritize alignment and strict containment protocols.
