# Semantic Kernel

Semantic Kernel is an open-source, MIT-licensed SDK from Microsoft for adding AI models to C#, Python, or Java applications. It includes an AI orchestration layer, plugins described with OpenAPI specifications, connectors to AI services, planners, and an agent layer for building agents and multi-agent collaboration. Microsoft has placed it in maintenance mode, with only critical bug and security fixes, and says it is superseded by Microsoft Agent Framework.
