The GenWorlds framework is an open-source development framework for multi-agent systems, designed to facilitate the creation of complex AI applications. It consists of a World, Agents, Objects, Memories, Brains, and a Simulation Socket that enables parallel operation and communication between these components. The framework is modular, flexible, and composable, allowing developers to easily create their own applications by plugging in or building individual elements. GenWorlds aims to make GenAI reliable and accessible, with a focus on modularity, flexibility, and composability, and has already demonstrated its capabilities through the development of the RoundTable podcast simulation application. The framework is designed to support various use cases, including sequential tasks, project management, tools, and more, making it a powerful tool for developers looking to create complex AI applications.
