SERA: self-evolving VLM harnesses tackle long-horizon robotic manipulation

Tingwen Du · hf · 2026-10-22

Researchers from USTC, Shanghai AI Lab, SJTU and others propose SERA to address long-horizon robotic manipulation, where non-Markovian dependencies require retaining task progress and past interaction outcomes while partial observability and execution errors compound over time. SERA uses a hierarchical design: an editable harness maintains task context and lets the VLM planner self-evolve its planning through execution feedback, paired with a fixed low-level VLA executor.
