Zetta ζ: An Efficient Closed-Loop Embodied Harness for Self-Evolving Physical Intelligence
Air Embodied Brain (multi-institution, 15 authors)
Zetta is a closed-loop embodied harness that evolves code-based runtime critics and recovery skills online while the base policy stays frozen, using three timescale-separated loops. With Z-Infra infrastructure it hits 90.8% on LIBERO-Pro and 93.6% on RoboCasa with an 11.1x inference speedup.
Why it matters
Top paper on HF Daily Papers for Aug 20 with 152 upvotes — establishes a practical recipe for letting embodied agents self-improve at execution time without retraining the base policy.
