The framework ElizaOS V2 of ai16z attempts to gradually evolve AI agents from the era of assistants to the era of independent agents. The core architecture of its V2 includes: 1. Modular core framework, facilitating developers to customize AI agents; 2. Unified abstraction layer for handling different chain assets; 3. Event driven architecture, convenient for processing real-time data. In addition, its V2 also adds a layered task network, which facilitates AI to decompose advanced goals into structured steps, such as asset management execution suitable for DeFi, and is also suitable for completing more complex tasks in games. From the evolution of virtualis, ai16z, swaps, arc, etc., there are two aspects that each company is paying attention to: one is the vision of truly independent AI agents; The second is the collaboration of multiple AI agents.
