$pi_texttt{RL}$: Online RL Fine-tuning for Flow-based Vision-Language-Action Models
arXiv:2510.25889v2 Announce Type: replace Abstract: Vision-Language-Action (VLA) models enable robots to understand and perform complex tasks from multimodal input. Although recent work explores using reinforcement learning (RL) to automate the laborious data collection process in scaling supervised fine-tuning (SFT), applying…
