An Anthropic researcher said he is resigning from the company over concerns the artificial intelligence firm and its competitors are not acting responsibly in AI development, echoing concerns raised inside and outside of the industry about the technology’s potential to elude human control.

Jacob Coxon, who said he spent three years doing research at both Anthropic and OpenAI, said Tuesday on the social platform X that the two AI companies are more focused on beating each other and global competitors in developing the most advanced model possible than they are on safety.
