Prefix-Caching Reduces Robot Simulation Training Tokens by 22x
July 8, 2026
A new training recipe uses prefix-caching to reduce training tokens by 22x, enabling training on 400,000 trajectories across 6,000 scenes in days rather than months. Implementation of online RL via CISPO further increases task success rates.
