Microsoft Agent Framework

Microsoft Agent Framework 1.0 (April 2026) is the official merger of AutoGen and Semantic Kernel into a single production-ready SDK for .NET and Python. Microsoft publishes a migration path from both predecessors; this is the recommended Microsoft path for new agentic applications.

OpenAI Agents SDK

OpenAI's production-grade agent framework, successor to Swarm. Core abstraction is explicit handoffs between agents carrying full context. Built for reliable multi-agent pipelines with native OpenAI tool use, tracing, and guardrails.
