What is FastAgency?
FastAgency is not a new agent framework but a unified programming interface for deploying agent workflows written with AG2 (formerly AutoGen) to development and production environments. With a few lines of code, you can create a web chat app or a REST API service that talks to your agents. When you need to scale, you can deploy as a distributed system that links multiple machines across multiple data centers using an internal message broker. It aims to move Jupyter notebook prototypes into production apps.
