Flow reversal steering guides high-level decision-making in diffusion-based VLAs

Flow reversal steering can "steer" diffusion-based vision-language-action models (VLAs) through high-level actions, such as high-level actions inferred from vision-language models (VLMs). It also lets us run reinforcement learning (RL) in the diffusion noise space, with high-level reasoning guiding exploration: think about the task first, then practice! 👇
