Zetta $ζ$: An Efficient Closed-Loop Embodied Harness for Self-Evolving Physical Intelligence
Zetta通过三时间尺度闭环在线演化运行时评判器与恢复技能，在LIBERO-Pro和RoboCasa上验证自演化物理智能。
核心要点
- 现有具身框架多为开环，执行中依赖固定技能，事后反思难以及时治理物理交互。
- Zetta冻结基础策略，在线演化代码化运行时评判器与恢复技能，实现闭环执行治理。
- 三类分离时间尺度循环分别负责动作频率治理、rollout级提案和验证门控技能更新。
- 在LIBERO-Pro和RoboCasa当前rollout预算下达到90.8%和93.6%成功率，并有11.1倍推理加速。
验证范围与局限：验证范围为LIBERO-Pro和RoboCasa当前rollout预算；摘要未说明真机验证或机器人数量。
英文摘要 (Abstract)
Embodied agents are increasingly used to close the gap left by end-to-end policy models. Yet the agentic path has not realized closed-loop learning in physical execution: existing harnesses remain largely open-loop, following fixed skills during rollout and reflecting only after an episode completes. Such post-hoc reflection cannot govern execution as it unfolds, because physical interaction requires decisions to track rapidly changing robot-environment states at a frequency beyond today's large agentic models. We present Zetta, a closed-loop embodied harness that evolves code-based runtime critics and recovery skills online while keeping the base policy frozen. Through three timescale-separated loops, Zetta provides action-frequency governance, rollout-level critic-recovery proposal, and validation-gated skill updates. Together with Z-Infra, a rollout infrastructure decoupling agent logic from heterogeneous execution resources, Zetta achieves state-of-the-art success on LIBERO-Pro and RoboCasa under our current rollout budget, reaching 90.8% and 93.6%, with an 11.1x inference speedup; success continues to scale with self-exploration experience; learned skills transfer zero-shot, and clear robotic "Aha Moments" emerge. These results show that closed-loop harness self-evolution opens a scaling path for reliable physical intelligence.
