Chris Fall has resigned as the director of the Center for AI Standards and Innovation (CAISI) after serving in the role for three months. Following his departure on July 21, 2026, Arvind Raman, the current director of the National Institute of Standards and Technology (NIST), will serve as the acting director of CAISI. According to a Commerce Department spokesperson, Raman is currently reviewing candidates for a permanent replacement, and Fall’s initial appointment was intended to be temporary.

Fall was appointed in April 2026, following the exit of Collin Burns, who left the position after four days. Reports indicated Burns was asked to leave due to his previous employment at Anthropic during a period of conflict between the Trump administration and the company. Before these appointments, venture capitalist David Sacks led the agency as the White House’s AI and crypto czar until he stepped down in March 2026 to join the Council of Advisors on Science and Technology.

CAISI functions under NIST to develop technical standards, establish testing protocols for AI models, and assess cybersecurity risks. The leadership turnover occurs as the Trump administration faces pressure to solidify AI policy amidst rising international competition. Notably, Chinese startup Moonshot AI recently released its Kimi K3 model, which the company claims outperforms advanced US systems on specific benchmarks.

This transition follows an executive order signed by the Trump administration that requires major AI companies—including OpenAI, Anthropic, and Google—to voluntarily submit models to federal agencies for capability assessments. The order mandates that agencies establish a formal evaluation framework within 60 days. Prior to his role at CAISI, Fall held leadership positions at the Department of Energy’s Office of Science and the Advanced Research Projects Agency-Energy during the first Trump administration.
