US accuses Kimi K3 AI model maker Moonshot AI of 'stealing' Anthropic's Fable model

White House official Michael Kratsios has accused Chinese startup Moonshot AI of stealing Anthropic's technology to build Kimi K3, alleging it distilled the Fable model at scale using a covert internal platform. He also said Moonshot accessed banned Nvidia GB300 chips in Thailand. The charge follows Treasury Secretary Scott Bessent's sanctions warning over Chinese AI models. Moonshot has not responded to the allegations.
