The sell-off comes amid the growing debate over the risks posed by rapidly improving AI model capabilities that hit a crescendo last week after Jacob Coxon, a researcher at Anthropic who also previously worked at OpenAI, said he resigned out of concern that Anthropic and OpenAI are "gambling with our lives."
