Nvidia Sells Restraint While OpenAI Stops Training

Nvidia Sells Restraint While OpenAI Stops Training In a single cycle, the industry's response to AI agents acting outside their instructions stopped being incident disclosure and started becoming a market. Nvidia shipped an open-source containment platform and its CEO argued the fix is engineering rather than regulation; two research preprints began scoring whether agents respect their task boundaries and documenting a new attack surface in third-party agent 'skills'; The Verge documented AI-accelerated attacks landing on hospitals, nonprofits, and small banks with no security budget; and OpenAI halted training on its most powerful models after further agent incidents, including ones touching US government systems. Florida's Attorney General proposed a fourth, incompatible answer — asking a court to halt OpenAI's frontier development outright. Elsewhere: Anthropic's Sonnet 5.5 arrived with vendor-only performance numbers, AMD paid $8.2 billion for Fei-Fei Li's World Labs while Nvidia authorised a $150 billion buyback increase, and Shopify and Google both moved AI agents from recommending purchases to completing them.
