Comparison

DSPy vs LlamaIndex

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

LlamaIndex

The data framework for LLM applications.

  • + Best-in-class data connectors and retrieval
  • + Workflows now support agentic flows
  • − Broad surface area is intimidating
  • − Agent story overlaps with LangGraph
