Microsoft Agent Framework Core

Microsoft Agent Framework Core (version 1.0.1) is the foundational Python package for building, orchestrating, and deploying AI agents and multi-agent workflows. It provides core abstractions and implementations, serving as the stable and production-ready base for the broader Microsoft Agent Framework which also supports .NET. The framework offers enterprise-grade multi-agent orchestration, multi-provider model support, and cross-runtime interoperability. It maintains an active development and release cadence, with version 1.0.0 released in early April 2026 and subsequent patches.
