What it is
DSPy is an open-source framework from Stanford for programming, rather than prompting, language-model workflows. You define small, natural-language Python modules, and DSPy compiles them into pipelines whose prompts (and even weights) are tuned automatically

Key features

  • Declarative modules: Write jobs as readable Python functions with NL “signatures”; no handcrafted prompt fiddling.
  • Auto-optimization: Built-in Teleprompter algorithms (e.g., BootstrapFewShot) learn optimal prompts/weights from data.
  • Composable pipelines: Chain modules to build RAG flows, agent loops, or evaluators out-of-the-box.
  • Model-agnostic: Swap backends, OpenAI, Anthropic, local Llama-family models, without code changes.
  • Production-ready: MIT-licensed, light-weight (pip install dspy-ai), latest v2.6.27 (released Jun 3 2025).
