Vercel Eve: Open-Source AI Agent Framework Released

Vercel has released Eve, an open-source framework designed for building, running, and scaling AI agents. This project is available as an npm package and is licensed under Apache-2.0. Eve is a filesystem-first framework where each agent is defined as a directory on disk. This directory's structure, with individual files describing components, shows what an agent is and does. For example, the smallest agent needs just two files: one to set the model and another for instructions. Vercel uses Eve to run over a hundred agents in production. The framework includes six production capabilities, such as durable execution, where every conversation is a durable workflow with checkpointed steps. This approach aims to simplify agent development by providing a clear, structured way to define their functionalities.
