Verl is an open-source reinforcement learning training library for large language models (LLMs), developed from ByteDance’s HybridFlow RLHF framework. It provides a flexible, production-ready platform that lets users extend RL algorithms via a hybrid-controller programming model and build RL dataflows (e.g., PPO) with minimal code, while seamlessly integrating with existing LLM infrastructure such as FSDP, Megatron-LM, vLLM, SGLang and HuggingFace models. It focuses on high throughput and scalable resource use with features like flexible device mapping and the 3D-HybridEngine, and its Verl-VLA release targets a unified post-training workflow for human-in-the-loop data collection, supervised fine-tuning, and RL across simulators, real robots, and distributed systems.
