Moonshot K3 timeline casts doubt on claims it was distilled from Anthropic’s Fable

This post pushes back on the claim that Moonshot AI’s K3 performance came from distilling Anthropic’s Fable.
- The author argues the timeline does not fit: only 15 days passed between the lifting of the Fable 5 ban and K3’s release.
- The implication is that K3’s results are unlikely to be explained purely by distillation from that model, even if some distillation happened.
- The quoted context also mentions a U.S. claim that Moonshot built internal infrastructure for large-scale distillation against U.S. models and accessed GB300 servers, including in Thailand.
