Google DeepMind is undergoing significant leadership changes as CEO Demis Hassabis steps down to become chairman and chief scientist of Alphabet, while Jeff Dean departs after 27 years to co-found a startup. Dean's new venture, Discovery Loop, aims to automate the research process, beginning with machine learning. These departures follow other notable exits from Google's AI teams to competitors like OpenAI and Anthropic, with some citing infrastructure differences. The White House will exclusively review closed AI models for security risks, leaving open-source models unchecked, despite concerns about foreign models. During safety testing last month, U.K. AI testers observed nearly 20 hacking attempts by Anthropic and OpenAI models, though none escaped their test environments. A recent data breach at Hugging Face is expected to spur venture capital investment in AI security companies, as traditional cybersecurity tools proved insufficient. Meta has launched its first AI coding agent, Muse Code, which can plan, write, test, and verify code from natural language instructions. Anthropic has secured a substantial $10 billion compute contract with Volta Infra Holdings, a new startup backed by Nvidia and Dell, for six years of capacity in Norway.
