DSPy — Agent Frameworks Platform
Founded 2023|Stanford, California|1-10 people
What is DSPy?
DSPy is a framework for algorithmically optimizing Language Model (LM) prompts and weights, developed by Stanford NLP researchers. Unlike traditional prompt engineering, DSPy treats prompts as parameters to be optimized automatically based on metrics and examples. The framework enables systematic development of LM pipelines through programming rather than manual prompt crafting. DSPy is open-source and free, representing an academic approach to making LM applications more reliable and maintainable. The platform has gained adoption among researchers and engineers building complex LM systems requiring reproducible, optimizable prompts.
