DSPy: Programming—not prompting—Foundation Models

Documentation: DSPy Docs

---

DSPy is the open-source framework for building high-quality, modular AI systems by programming—rather than prompting—language models. It provides abstractions and algorithms for optimizing the prompts and weights in LM programs, ranging from simple classifiers to sophisticated RAG pipelines and Agent loops.

Instead of writing brittle LM-specific prompts, you write compositional code and use DSPy optimizers to teach different models like GPT-4o or Llama-3.2 to deliver higher quality outputs or avoid specific failure patterns. In essence, DSPy optimizers then compile your high-level code into low-level computations, prompts, or weight updates that align your LM with your program’s structure and metrics.

DSPy stands for Declarative Self-improving Python. This recent lecture is a good conceptual introduction. Our Discord server is a great place to meet the community, seek help, or start contributing.
