-**DSPy** is the framework for solving advanced tasks with language models (LMs) and retrieval models (RMs). **DSPy** unifies techniques for **prompting** and **fine-tuning** LMs and approaches for **reasoning** and **tool/retrieval augmentation**. In DSPy, all of these are expressed through a small set of Pythonic modules _that compose and learn_.
