## Overview

DSPy expresses language-model programs with input/output signatures and composable modules for classification, RAG and agent loops. Developers supply examples and metrics, then choose optimizers for prompts, demonstrations or supported weight-training workflows. Iteration becomes an evaluable development process; improvements depend on data, objectives and the selected model.
