Semantic Kernel
An open-source AI orchestration framework introduced by Microsoft in 2023. It systematically introduced the Skills/Plugins concept, enabling large language models to automatically select and execute semantically described callable functions via a Function Calling mechanism.
Core Facts
Timeline (last 90 days)
Semantic Kernel is an enterprise-oriented SDK that emphasizes engineering capabilities such as plugins, memory, middleware, and telemetry.
Whether using LangChain, LangGraph, CrewAI, AutoGen, or Semantic Kernel, effective patterns include: plan first then execute, separate retrieval from reasoning, and explicit handoffs; the framework matters far less than the pattern.
LangChain's Runnable system, LlamaIndex's Query Engine, and Microsoft's Semantic Kernel are all harness-type projects.
Among the eight frameworks named in the launch post, six—LangGraph, OpenAI Agents SDK, Semantic Kernel, LlamaIndex, CrewAI, and Claude Agent SDK—have no file records whatsoever in the agent-hooks repository.
A survey of 12 mainstream Agent frameworks found that none of the frameworks provides monetary-denominated tool-call budget control in its documentation (C5 is all no).
AutoGen has entered maintenance mode, the README explicitly states that it no longer accepts new features, and the official recommendation for new users is to move to Microsoft Agent Framework, whose successor officially became GA on April 3, 2026.
Frameworks matter far less than patterns; patterns that continue to be effective include plan-then-execute, separating retrieval from reasoning, and explicit handoffs.
Frameworks matter far less than architectural patterns; patterns that continue to work include plan-then-execute, separating retrieval from reasoning, and explicit handoffs.
Semantic Kernel is Microsoft's enterprise-oriented SDK, deeply integrated with the Azure ecosystem.
Common orchestration frameworks include LangGraph, AutoGen, CrewAI, and Semantic Kernel.
