ArgusOrch: A Multi-Agent Reinforcement Learning Infrastructure for Large Language Models

ArgusOrch is a multi-agent reinforcement learning (MARL) infrastructure library for large language models (LLMs). It adopts a Centralized Training with Decentralized Execution (CTDE) architecture and provides technical support for building collaborative AI agent systems. It aims to address challenges in traditional MARL such as coordination difficulties and low training efficiency, and enhances decision-making quality by integrating the reasoning capabilities of LLMs.

Multi-agent systems are an important direction in AI research. The improvement of LLM capabilities has promoted the exploration of combining LLMs with MARL. Traditional MARL faces challenges such as difficult coordination, low efficiency, and insufficient generalization. LLMs provide new ideas to solve these problems, and the ArgusOrch project was born in this context.

ArgusOrch uses the CTDE architecture: During the training phase, the centralized critic uses global information to learn accurate value functions, solving the credit assignment problem; during the execution phase, agents make decisions based on local observations, reducing communication overhead. The advantages of the centralized critic include a global perspective, promotion of collaboration, and reduction of redundant computations.

LLMs serve as policy networks, with advantages such as complex semantic understanding, multi-step reasoning, and zero-shot learning. The project supports reinforcement learning fine-tuning based on environmental feedback to optimize the decision-making ability of LLMs in specific tasks.

Application scenarios include collaborative robots (warehouse logistics), intelligent customer service (multi-expert collaboration), game AI (team tactics), and scientific research assistance (interdisciplinary collaboration).

For large-scale parameter training, PEFT and distributed frameworks are used; credit assignment is solved by combining centralized critics with value decomposition; communication coordination uses reasonable protocols to balance information exchange and overload.

Open-source provides a unified experimental platform, supporting comparative experiments, resource sharing, and result reproduction, accelerating the development of the field combining LLMs and MARL.

ArgusOrch is an important direction for combining LLMs and MARL. The CTDE architecture lays the foundation for collaborative AI, and it will play a more important role in the future development of AI.
