Anthropic researcher quits, warns self-improving AI is 'gambling with our lives'

‘Gambling with our lives’: Anthropic researcher quits, warns against self-improving AI

Anthropic researcher Jacob Coxon resigned Tuesday night after three years of pretraining work at OpenAI and Anthropic. He accused both labs of failing to act responsibly and warned that self-improving AI models could lead to extinction. He called for pacing agreements among AI labs to slow frontier model development. The article does not include an official response from Anthropic or OpenAI.

Why it matters: An internal Anthropic researcher quitting publicly and warning about self-improving AI is a high-signal personnel + safety event. HKR hits all three, but the article is a TechCrunch recap of a public statement with no original investigation or new data, so it stays below 85.
