Researchers have introduced QF3, a novel off-policy reinforcement learning algorithm designed to accelerate the training of flow policies for robotic behaviors. This method integrates flow matching with the critic's action gradient, selectively applying updates where predictions are reliable. QF3 has demonstrated the ability to train humanoid locomotion policies from scratch and achieve zero-shot transfer to hardware, outperforming recent on-policy methods by a factor of 10 in wall-clock speed. The algorithm also shows effectiveness in fine-tuning pre-trained manipulation policies on simulation tasks. AI
