About DSPy

DSPy (Declarative Self‑improving Python) is a framework that lets developers program foundation models using compositional Python modules instead of brittle prompt engineering. Users declare inputs and outputs, compose modular components (classifiers, retrievers, agents, RAG pipelines), and DSPy compiles prompt templates, runs evaluations, and applies iterative optimizers to improve prompts and module parameters automatically. The framework includes built-in optimizers (e.g., BootstrapFewShot, BetterTogether), an evaluation API with metrics and dataset support, and tooling to iterate quickly on modular AI systems, yielding higher accuracy and consistency without manual tuning.

Key Features

Declarative Module System: Define compositional Python modules with explicit inputs and outputs; DSPy compiles these declarations into prompt templates and executable model calls.
Iterative Optimizers: Built-in optimizers (e.g., BootstrapFewShot, BetterTogether) automatically generate prompt/parameter variants, test them on examples, and retain the best-performing versions to improve accuracy and consistency over time.
Evaluation API: Flexible evaluation framework with built-in metrics and support for custom metrics and datasets, enabling systematic measurement and comparison of module performance during development and optimization.
RAG and Agent Support: First-class support for building Retrieval-Augmented Generation pipelines and agent loops, enabling complex multi-step workflows and tool-augmented agents.
Modular Pipeline Composition: Easily compose classifiers, retrievers, and generators into end-to-end pipelines for rapid iteration and reuse of components across projects.
Multi-backend Integration: Designed to work with external LLM APIs, retrieval systems, and tool integrations (examples and community repos demonstrate connectors to common model APIs and data sources).
Installation and Packaging: Distributed via pip and conda-forge (pip install dspy / conda install dspy), with source and examples available on GitHub for easy adoption and extension.
