Is LIBERO still meaningful?
Status:Flawed Checked against the report, 5 November 2026
Verdict
No. High scores reflect memorised action sequences and collapse when the scene shifts slightly.
Why flawed: LIBERO-PRO and LIBERO-Plus found that scores above 90% fell to 0–30% under small perturbations.[1][1] LIBERO-PRO, arXiv 2510.03827 Primary[2][2] LIBERO-Plus, arXiv 2510.13626 Primary The chapter lists LIBERO as Saturated.
What “Flawed” meansKnown problems
- Policies that scored above 90% collapsed to 0% under changed objects, start states, instructions or scenes. The authors call this "rote memorization of action sequences".[1][1] LIBERO-PRO, arXiv 2510.03827 Primary
- Modest camera and start-state shifts cut success from 95% to below 30%.[2][2] LIBERO-Plus, arXiv 2510.13626 Primary
- Most robot papers run too few rollouts. Seventy rollouts at 90% success leave a band about 15 points wide.[4][4] The Robot Report on NVIDIA robot evaluation Secondary
- Its code last changed in March 2025.[5][5] GitHub, LIBERO Primary
What to look at instead
LIBERO-PRO and LIBERO-Plus re-test LIBERO policies under perturbations.[1][1] LIBERO-PRO, arXiv 2510.03827 Primary[2][2] LIBERO-Plus, arXiv 2510.13626 Primary
- BEHAVIOR-1K Status:Still useful Yes. The best challenge entry succeeds on only 12.4% of tasks, which leaves much room.
