Sam Gao, a consultant at ai16z, said on social media that Eliza's technical white paper "Eliza: An AI Agent Operating System for Web3" was officially released. With large language models (LLMs) as its cognitive core, AI Agent is an intelligent agent system that can autonomously control and decide the execution path according to the user's instructions. With the explosion of LLM capabilities and the introduction of various plug-ins (such as RAG, text-to-image/video/3D, etc.), the potential of AI Agent has been greatly expanded, and its capabilities have become increasingly powerful. However, at the intersection of AI and Web3, there is currently no ideal agent framework that can seamlessly integrate Web3 applications into the functions of AI Agent. Eliza is the first open-source smart proxy framework for Web3, making it easy to deploy Web3 applications. Each part of Eliza is a regular Typescript program, fully controlled by the user, and can integrate seamlessly with Web3 (such as reading and writing blockchain data, interacting with smart contracts, etc.). In addition, we show a practical implementation of the core components of the Eliza runtime, how to ensure its stable performance. The code is currently public.
