Weng, Lilian. (Jun 2023). LLM-powered Autonomous Agents". Lil’Log. https://lilianweng.github.io/posts/2023-06-23-agent/.
This is a comprehensive blog post by Lilian Weng that surveys the design and components of LLM-powered autonomous agents. The article introduces a structured framework where a large language model serves as the central controller, augmented with planning, memory, and tool use capabilities. It breaks down agent systems into three key components: planning (including task decomposition and self-reflection), memory (short-term and long-term, with vector stores for retrieval), and tool use (such as calling external APIs and executing code). The post provides an in-depth review of techniques like Chain of Thought, Tree of Thoughts, LLM+P, ReAct, Reflexion, and more, along with discussions on maximum inner product search (MIPS) for memory retrieval. It also presents several case studies, including scientific discovery agents and generative agents simulation, and highlights challenges such as hallucination, context length limitations, and reliability. Overall, the article serves as a foundational reference for understanding and building autonomous agents with LLMs, combining theoretical insights with practical examples from existing projects like AutoGPT and BabyAGI.
