DSPy vs Semantic Kernel

A like-for-like, spec-level comparison. Both entries are verified against their docs and repo.

DSPy

Declarative, programmable prompt programming from Stanford.

  • + Compiles and optimizes prompts instead of hand-writing them
  • + Strong for repeatable, measurable prompt engineering
  • − Different mental model from typical agent frameworks
  • − Smaller ecosystem of tool integrations

Semantic Kernel

Microsoft's SDK for enterprise AI orchestration.

  • + Strong .NET and Java story for enterprise
  • + Planner abstraction for tool orchestration
  • − Enterprise-flavored, less hacker-friendly
  • − Concept-heavy docs
