Semantic Kernel is a model-agnostic SDK developed by Microsoft that enables developers to build, orchestrate, and deploy AI agents and multi-agent systems. The repository serves as a framework for integrating large language model technology into applications, supporting multiple programming languages including C#, Python, and Java. According to the README, Semantic Kernel has transitioned into Microsoft Agent Framework, which is positioned as the enterprise-ready successor offering production-ready release status with stable APIs and long-term support commitments.
The framework provides flexibility in model connectivity, with built-in support for OpenAI, Azure OpenAI, Hugging Face, and Nvidia services. Developers can construct modular AI agents equipped with access to tools, plugins, memory, and planning capabilities. The system supports multi-agent orchestration for complex workflows involving collaborating specialist agents. The plugin ecosystem allows extension through native code functions, prompt templates, OpenAPI specifications, and Model Context Protocol integration. Vector database support includes seamless integration with Azure AI Search, Elasticsearch, and Chroma.
Semantic Kernel accommodates multimodal inputs including text, vision, and audio processing. It supports local deployment options through Ollama, LMStudio, and ONNX. The framework includes a process framework for modeling complex business processes with structured workflow approaches and emphasizes enterprise readiness through observability, security, and stable API design. System requirements span Python 3.10 and above, .NET 10.0 and above, and Java JDK 17 and above, with support for Windows, macOS, and Linux operating systems.
