White House Accuses Moonshot AI of Distilling Anthropic’s Fable for Kimi K3

Model distillation uses a stronger system’s outputs to train another model, improving efficiency but potentially breaching terms of service or intellectual-property protections. Beijing-based Moonshot AI has put those tensions at the center of the U.S.-China technology contest with Kimi K3, a 2.8-trillion-parameter open-weight model. Its API costs $15 per million output tokens, versus $50 for Anthropic’s Fable, sharpening debate over whether low-cost Chinese models reflect domestic innovation or unauthorized use of U.S. technology.

White House Office of Science and Technology Policy Director Michael Kratsios said on July 22 that Moonshot built an internal platform to evade detection while distilling Anthropic’s Fable, and alleged access to restricted Nvidia GB300 chips. He offered no public evidence, and Moonshot did not respond. Fable became available on July 1, just 15 days before K3’s July 16 preview. OpenAI’s Dean Ball and other researchers said that timetable made distillation an insufficient explanation for K3’s performance.
