OpenManus/OpenManus-RL
OpenManus RL
OpenManus-RL is a reinforcement learning framework and distributed training pipeline designed to train large language models as agents. It serves as an agentic reasoning optimizer and reward model trainer, providing the infrastructure to improve model decision-making through reward-based policy optimization.
The project distinguishes itself through a distributed architecture that supports parameter sharding across multiple compute nodes and a coordinated rollout system for collecting interaction trajectories. It incorporates advanced reasoning strategies, such as Tree-of-Thoughts and Monte Carlo Tree Search, to explore branching decision paths and optimize trajectories during both training and test-time inference.
The system covers a broad range of capabilities including policy optimization via Proximal Policy Optimization, the development of specialized reward models to quantify performance signals, and the orchestration of custom task environments using conda-based specifications. It also includes utilities for training data standardization and the management of tensor-metadata storage to handle distributed workloads.
