Chris Fall has resigned as director of the Center for AI Standards and Innovation just three months after his appointment by the Trump administration, the Commerce Department confirmed Monday without disclosing a reason. Arvind Raman, director of the National Institute of Standards and Technology, will serve as acting head of the agency.
The departure marks the latest shift in the administration's approach to artificial intelligence following the March exit of White House AI and crypto czar David Sacks. CAISI, housed within the Commerce Department, evaluates advanced AI models for verifiable risks and collaborates with leading laboratories including OpenAI, Anthropic, Google DeepMind, Microsoft, and xAI to test unreleased models for security vulnerabilities.
The institute's mission includes preventing adversaries from exploiting AI to develop chemical or biological weapons or corrupt training data. Its work has gained urgency as major developers face mounting government oversight, with OpenAI agreeing in June to limit GPT-5.6 deployment to trusted partners and Anthropic disabling access to certain models under export controls.
