The short version

  • Each has a real cost: Semantic Kernel steep learning curve for advanced features; Tigris lowest tier still more expensive than some cold storage alternatives
  • They diverge on capability: Semantic Kernel covers Multi-model support, Tigris covers Global Distribution.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

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

Tigris

  • Lowest tier still more expensive than some cold storage alternatives
  • Retrieval charges on infrequent access tier add cost variability
  • Limited to object storage, no file system semantics
  • Archive retrieval requires planning ahead
