An Anthropic researcher, Jacob Coxon, announces his resignation and says he is leaving the AI industry, posting the decision on X. He argues that both OpenAI and Anthropic are not acting responsibly as they pursue increasingly advanced models.

Coxon, who has worked across both companies—spending about three years at OpenAI before moving to Anthropic—frames his departure as a protest against what he describes as a race toward self-improving superintelligence. The Independent reports his concerns in stronger terms, including the view that AI risks could become catastrophic within the decade, while other outlets focus more generally on the allegation that current development practices are dangerously reckless.

Business Insider and The Next Web characterize the resignation as the latest insider warning in the broader debate over safety and accountability in leading AI labs. Across coverage, the common thread is Coxon’s claim that both firms are accelerating progress without sufficient safeguards, prompting him to step away from the field.
