Kimi K3 Frequently Claims to Be Claude
RyanGreenblatt · x · 2026-07-19
Ryan Greenblatt observed an interesting phenomenon: the Kimi K3 model unusually often claims to be Claude.
- He used Opus 4.8 to research and analyze this.
- Tests revealed that K3 identifies itself as Claude 4.5, whereas actual Claude models do not do this.
- K3 did not show any tendency to claim other identities like Mythos or Fable.
