Chris Fall, the director of the Center for AI Standards and Innovation (CAISI), stepped down after just three months in the role, the agency told several news outlets on Tuesday. Fall, who previously led the Department of Energy’s Office of Science during the first Trump administration and served as acting director of the DOE’s Advanced Research Projects Agency‑Energy, was appointed to CAISI following the brief tenure of Collin Burns.

Burns, a former Anthropic employee, left the post in less than a week after the Trump administration reportedly pushed him out in April. Before Burns, venture capitalist David Sacks held the position under the title of White House AI and crypto czar before stepping down in March.

CAISI, housed within the National Institute of Standards and Technology, is tasked with creating technical standards, testing methods for artificial‑intelligence models and assessing related cybersecurity risks. Yet the agency has not been at the center of the latest model‑risk controversy. In June, the Commerce Department invoked an obscure export‑control rule that forced Anthropic to withdraw its Mythos and Fable models. The ban was lifted by the end of the month after Secretary of Commerce Howard Lutnick said he was satisfied with the company’s safety plans.

Earlier this month, the White House signed an executive order establishing the “Gold Eagle” AI‑safety oversight program, a clearinghouse for coordinating cybersecurity vulnerabilities. While dozens of federal entities joined the effort, CAISI was not listed among them.

After Anthropic’s models returned to the market, DeepMind CEO Demis Hassabis called for an independent, industry‑run standards body modeled after FINRA – a mission that mirrors CAISI’s original purpose. Fall’s resignation coincides with heightened scrutiny of Chinese AI labs. Moonshot’s new open‑weight model Kimi performed competitively against leading frontier models, prompting the administration to consider a ban on Chinese open models, according to Axios.

Debate erupted over the proposal, with former CAISI head David Sacks arguing that regulation should not serve as protectionism for U.S. AI firms. CAISI has released limited reports on Chinese open‑weight models such as Z.ai’s GLM‑5.2 and DeepSeek V4 Pro but has offered little detail on its testing procedures. Since July 9, TechCrunch has sent multiple inquiries to the Department of Commerce and NIST about the agency’s LLM evaluation methods without receiving a response.

Fall’s departure adds another layer of uncertainty to an already turbulent period for U.S. AI policy, as the administration balances domestic standards, international competition and emerging safety frameworks.
