PAI3 is a project that integrates Web3 and artificial intelligence, reshaping the underlying architecture of artificial intelligence by building a personal AI network. It aims to create a transparent, user-owned environment for AI agents to operate, with controllable and auditable data privacy, and to share the AI economy through Node sharing. Unlike traditional AI on-chain models, PAI3 is dedicated to building Web3 infrastructure specifically designed for AI, transforming smart technology from platform assets into public resources.
