LightAgent: Production-level Open-source Agentic AI Framework

2025-09-11

AI Summary

Existing multi-agent system (MAS) frameworks struggle to balance flexibility and simplicity. To address this, we propose and implement AgentLite—a lightweight, open-source agent AI framework. AgentLite adopts a modular architecture with native integration of memory (mem0), tool-use capabilities, and the Tree-of-Thought (ToT) reasoning mechanism, enabling large language model (LLM)-driven multi-agent collaboration and self-improving agent construction. Compared to mainstream frameworks, AgentLite significantly reduces development and deployment complexity while preserving high extensibility and production readiness. It supports seamless integration with major chat platforms. The entire project is open-sourced under permissive licenses. AgentLite establishes a novel infrastructure for MAS research and applications, uniquely combining efficiency, robustness, and usability—thereby advancing accessible, scalable, and practical multi-agent AI development.

Abstract

With the rapid advancement of large language models (LLMs), Multi-agent Systems (MAS) have achieved significant progress in various application scenarios. However, substantial challenges remain in designing versatile, robust, and efficient platforms for agent deployment. To address these limitations, we propose extbf{LightAgent}, a lightweight yet powerful agentic framework, effectively resolving the trade-off between flexibility and simplicity found in existing frameworks. LightAgent integrates core functionalities such as Memory (mem0), Tools, and Tree of Thought (ToT), while maintaining an extremely lightweight structure. As a fully open-source solution, it seamlessly integrates with mainstream chat platforms, enabling developers to easily build self-learning agents. We have released LightAgent at href{https://github.com/wxai-space/LightAgent}{https://github.com/wxai-space/LightAgent}
