Intro to DSPy: Simple Ideas To Improve Your RAG

Language models (LMs) like GPT-4 have transformed how we interact with machine learning systems, tackling tasks from code generation to creating detailed travel plans. However, these models often need help with reliability issues, short memory spans, hallucinations, and difficulty updating knowledge.

Optimizing these models for complex tasks traditionally required manual steps, such as fine-tuning prompts and fine-tuning weights, is a laborious and costly process.

This is where DSPy comes in: a framework designed to address application issues based on language models (LMs), prioritizing programming over prompts.

In this article, we will provide an easy-to-understand explanation of DSPy’s overview, what makes DSPy unique? How is DSPy different from LangChain or LlamaIndex? and even build an actual application.

DSPy is a framework developed by Stanford University that can automatically optimize LLM prompts and weights. DSPy is conceptually similar to PyTorch. You define modules in your program, treat the prompts you use as weights for the model, and train the optimal prompts on the training data. In DSPy, this training… Read the full blog for free on Medium.
