Reviewer scorecard
“One API, every model. The OpenAI-compatible format means zero code changes to switch models. Fallback routing is clutch.”
“If you're in the .NET ecosystem, this is the best AI integration SDK. Plugin architecture is clean and extensible.”
“Small markup over direct API pricing but the convenience and fallback routing are worth it for production apps.”
“Microsoft vendor lock-in disguised as open source. Everything points you toward Azure. Use provider-agnostic alternatives.”
“Model diversity will only increase. A unified API layer becomes more valuable as the model landscape fragments.”
“Enterprise AI adoption will go through existing stacks. Semantic Kernel meets .NET developers where they are.”
