Microsoft Agent Framework now available for Go, while OpenAI and Anthropic lag in language support
Microsoft has released its Agent Framework for Go to public preview, joining Google in offering native AI agent tooling for a language that dominates cloud infrastructure, leaving two major AI players behind.
The New Stack
Go has long been the default choice for cloud infrastructure, powering Kubernetes, Docker, and countless backend services. Now Microsoft is making it a first-class environment for building AI agents, too.
The tech giant has brought its Agent Framework to Go in public preview, offering cloud-native developers the ability to construct production-grade agent systems without switching languages. The move addresses a gap developers have faced: while AI agent SDKs existed for Python and .NET, Go remained unsupported by most major tooling vendors.
Building production agents in Go#
Microsoft's Go implementation includes the same core capabilities offered in Python and .NET versions: integrations with models from Azure OpenAI, Anthropic, Gemini, and Microsoft Foundry; tool-calling and Model Context Protocol (MCP) support for external system connections; and orchestration features for multi-agent workflows.
According to Microsoft's announcement, the framework targets developers transitioning beyond simple prompt-based applications toward full-featured systems. These systems require context management, tool use, inter-agent coordination, result streaming, and governance—capabilities that Go developers can now access natively in their language of choice.
The release includes graph-based workflow orchestration with support for conditional routing, subworkflows, checkpointing, and human-in-the-loop review. Developer Pratik Dhanave highlighted the significance on LinkedIn: "This is production-grade orchestration, not a chat loop wrapper."
Partial feature parity and the gap-closing path#
The public preview doesn't yet match the .NET version entirely. Handoff orchestration and CodeAct (a faster tool-calling method) remain unavailable in Go, though Microsoft's transparent documentation about these gaps has earned community appreciation.
The framework itself represents the consolidation of Microsoft's earlier AutoGen and Semantic Kernel projects, which launched as an open-source initiative in October 2025 and reached general availability in April 2026. Go support was requested by the community as early as October 2025, with Microsoft signaling at that time the effort would take "at least a few months."
Google leads, but OpenAI and Anthropic absent#
Microsoft isn't pioneering AI agent frameworks in Go alone. Google released its own in November 2025, with a formal 1.0 launch this past March.
