DSPy
Stanford NLPStanford framework for 'programming - not prompting - language models': compose typed declarative modules (signatures, Predict/ChainOfThought/ReAct) into pipelines, then hand them to optimizers (MIPROv2, BootstrapFewShot, GEPA) that auto-tune prompts and/or weights against a metric.
