Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Grok

  • Pricing is not published; all access requires sales contact or account negotiation
  • Limited ecosystem compared to OpenAI and Anthropic; fewer third-party integrations
  • Organisational reputation tied to Elon Musk; policy or direction changes may affect service continuity

Semantic Kernel

  • Steep learning curve for advanced features
  • Documentation focuses on Azure cloud services
  • Configuration complexity for multi-model scenarios
  • Requires understanding of AI/LLM concepts
