AI News Brief: Chris Fall has resigned as director of the US Center for AI Standards and Innovation (CAISI), confirmed by the agency to multiple media outlets though no reason was given. Fall took the position just three months ago, succeeding Collin Burns who left after less than a week — reportedly due to his prior work at Anthropic while the Trump administration was feuding with the company. Before them, CAISI was led by venture capitalist David Sacks as White House AI and crypto policy chief until his March departure. Fall previously served as DOE Office of Science director (first Trump term) and acting ARPA-E director. CAISI sits under NIST and handles AI model technical standards, testing methods, and cybersecurity risk assessment, but was not the lead agency in the June Commerce export-control dispute over Anthropic’s Mythos and Fable models. This month the White House signed an executive order creating the Gold Eagle AI safety oversight plan, which notably excluded CAISI. Meanwhile, Google DeepMind CEO Demis Hassabis called for an independent industry standards body modeled after FINRA to regulate frontier AI — exactly what CAISI was created to do. Fall’s resignation comes as China’s Moonshot released Kimi, whose performance approaches frontier-level models, reigniting debate over whether the US should ban Chinese open-source models.
