Anthropic accused Alibaba of illicitly extracting Claude's model capabilities, drawing 829 Hacker News comments and raising fresh questions about AI IP enforcement. OpenAI unveiled Jalapeño, its first custom inference chip built with Broadcom, a move that reshapes its dependency on Nvidia. GLM-5.2 crossed a threshold Nathan Lambert called the step change for open agents.
