   LimX Dynamics updates the FluxVLA Engine V2 technical report, adding online reinforcement learning and real-robot deployment evaluations

   LimX Dynamics has updated the second version of the technical report for its open-source embodied engineering foundation FluxVLA Engine. Compared with the first version in September, it newly adds post-training experiments with online reinforcement learning and expands the coverage of simulation evaluations and real-robot deployment. The report shows that after online reinforcement learning, SmolVLA's success rates on the ten tasks of LIBERO-10 and RoboTwin Clean increased by 10.0 and 15.4 percentage points, respectively; the inference frequency of 8 model-and-device combinations increased to 2.31–9.64 times. On the real-robot side, the deployment pipeline from model checkpoint to closed-loop execution was validated on ALOHA, the dual-arm Franka, Rebot, and the self-developed humanoid robot LimX Oli.

   LimX Dynamics Releases FluxVLA Engine V2 Technical Report, Adding Online Reinforcement Learning and Real-Robot Deployment Validation

   LimX Dynamics has updated the second version of the technical report for its open-source engineering foundation FluxVLA Engine. Compared with the first version in September, it adds post-training experiments with online reinforcement learning and expands the coverage of simulation evaluation and real-robot deployment. The report shows that 14 policies were integrated into the same LIBERO closed-loop evaluation, and the inference frequency of 8 model-device combinations increased to 2.31–9.64 times; after online reinforcement learning, SmolVLA's success rates on LIBERO-10 and the ten tasks of RoboTwin Clean increased by 10.0 and 15.4 percentage points, respectively. The deployment pipeline has been validated on platforms including ALOHA, dual-arm Franka, Rebot, and LimX Oli.

   LimX Dynamics' Open-Source FluxVLA Engine Update Connects the Entire Embodied Intelligence Pipeline from Data and Training to Evaluation and Deployment

   LimX Dynamics' open-source embodied intelligence engineering foundation FluxVLA Engine completed a major update on October 22. The technical report shows that it has incorporated heterogeneous policies such as OpenVLA, π0.5, DiT4DiT, and GR00T into a single pipeline for data, training, evaluation, and deployment. On the NVIDIA AGX Orin 64GB, GR00T's inference frequency increased from 3.2Hz to 7.4Hz, and π0.5 from 1.4Hz to 4.4Hz; together with RTC and a three-step trajectory post-processing mechanism, it connects to real-robot execution. In terms of online RL, SmolVLA's success rate on LIBERO-10 rose from 66.2% to 76.2%, and on 10 tasks in RoboTwin Clean from 45.9% to 61.3%.
