Pricing summary
The GitHub repository is MIT licensed, and Microsoft does not list a fee for the framework. You pay whatever model or cloud provider you connect. Microsoft's overview says you are responsible for those third-party costs.
open-source
This is a framework and a harness, not a finished chatbot. Microsoft says to prefer an ordinary function when the task does not need an agent.
