Semantic Kernel: features, pricing and alternatives
Semantic Kernel is a framework tool listed at Free. It is best for building agents and LLM applications in code.
What Semantic Kernel does
Frameworks provide abstractions for prompts, tools, retrieval and agents. The trade-off is speed of development versus control and debuggability.
A thin framework is easier to reason about than a large one. Start with the smallest abstraction that solves your problem and keep the ability to call the model directly.
