Reinforcement Fine-Tuning of Flow-Matching Policies for Vision-Language-Action Models

Read the original on arXiv Machine Learning →

arXiv:2510. 09976v2 Announce Type: replace Abstract: Vision-Language-Action (VLA) models such as OpenVLA, Octo, and $\pi_0$ have shown strong generalization by leveraging large-scale demonstrations, yet their performance is still fundamentally constrained by the quality and coverage of supervised data.
