Zetta is an open-source closed-loop embodied harness for self-evolving physical intelligence. It keeps a base policy frozen while evolving code-based runtime critics and recovery skills when rollouts fail.
Its evolution protocol clusters failed trajectories, uses a diagnostic stage to identify an observable causal failure mechanism, generates Critic-Recovery candidates under fixed tool schemas, and checks them through shadow replay, paired same-seed evaluation, and held-out seeds. Candidates are rejected or promoted based on these gates; the critic may propose recovery actions, a higher-level role approves them, and a bounded recovery actor executes only approved programs.
The repository provides campaign management, rollout workers and environment backends for systems including LIBERO, RoboCasa, RoboTwin, and Genie Sim, along with manifests, tool catalogs, audit records, deployment helpers, and contract tests. It supports Python 3.10–3.12, while simulator assets, model weights, credentials, and host runtime files remain outside the repository.
