White House accuses AI company Moonshot of copying a rival's model; experts say the timeline doesn't work

White House advisor Michael Kratsios accused Moonshot of secretly copying Anthropic's Fable AI model to build its own Kimi K3. Experts say this is implausible: Fable was only publicly available from July 1, 2026 — two weeks before K3 launched. AI2's Nathan Lambert says copying Fable's capabilities would require tens of millions of automated training runs, far too costly through any API. No evidence was shared, and officials did not define the "watermarks" cited. Moonshot plans to publish its full model and training details by July 27 for outside review.
