 DSPy is a declarative framework for building modular AI software. It allows you to **iterate fast on structured code**, rather than brittle strings, and offers algorithms that **compile AI programs into effective prompts and weights** for your language models, whether you're building simple classifiers, sophisticated RAG pipelines, or Agent loops.
