The short version

  • Only Semantic Kernel has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mistral AI smaller model selection compared to OpenAI; Mistral Medium 3.5 significantly more expensive than competing mid-tier models; Semantic Kernel steep learning curve for advanced features
  • Prices and features above were last checked on 29 August 2026.
