RL-GPT: Integrating Reinforcement Learning and Code-as-policy
CoRR(2024)
摘要
Large Language Models (LLMs) have demonstrated proficiency in utilizing
various tools by coding, yet they face limitations in handling intricate logic
and precise control. In embodied tasks, high-level planning is amenable to
direct coding, while low-level actions often necessitate task-specific
refinement, such as Reinforcement Learning (RL). To seamlessly integrate both
modalities, we introduce a two-level hierarchical framework, RL-GPT, comprising
a slow agent and a fast agent. The slow agent analyzes actions suitable for
coding, while the fast agent executes coding tasks. This decomposition
effectively focuses each agent on specific tasks, proving highly efficient
within our pipeline. Our approach outperforms traditional RL methods and
existing GPT agents, demonstrating superior efficiency. In the Minecraft game,
it rapidly obtains diamonds within a single day on an RTX3090. Additionally, it
achieves SOTA performance across all designated MineDojo tasks.
