Worked on the volcengine/verl repository to deliver reinforcement learning capabilities for flow-matching-based VLA models, focusing on the integration and optimization of the Pi0.5 model using Python and PyTorch. Developed and validated a full Soft Actor-Critic (SAC) algorithm, including Flow-SDE-based action exploration and end-to-end support for RL training and evaluation. Enhanced the training pipeline with tunable parameters, upgraded critic networks, and improved experiment instrumentation, resulting in robust policy performance and clearer diagnostics. Refactored core components for maintainability and scalability, while preparing scripts and documentation to support production-grade workflows and future research in deep learning and reinforcement learning.

Feb 1, 2026February 2026 focused on delivering reinforcement learning capabilities for flow-matching based VLA models in Verl, with end-to-end Pi0.5 support and a PyTorch-ready workflow. Implemented a full Soft Actor-Critic (SAC) algorithm and Pi0.5 model support, enabling RL training for flow-based policies. Validated PyTorch conversion of Pi0.5 checkpoints via giga-models and confirmed execution in the LIBERO simulator using a LIBERO-finetuned Pi0.5 checkpoint. Reproduced the flow-SDE method to produce action probabilities required by SAC, aligning with pi-RL research. Prepared training scripts and documentation to enable production-grade RL workflows and future experiments.
