Fable 5.2 Robot Control Demo Sped Up 60x, Sparking Pushback on "Robot Lab Is Dead" Hype

kaixhin · x · 2026-11-10

Anthropic's Fable 5.2 claims substantially improved physical robot control, outperforming other models and most dedicated robot AI systems on the two-arm RoboDojo benchmark, including tasks never explicitly trained. But @eternaIentropy points out the demo footage is sped up 60x with pauses removed ("60× · pauses cut"). The capability jump is real, he argues, but inference speed and reliability remain far from usable — so stop declaring "robot foundation model labs are dead."
