When building applications with LLMs, writing effective prompts is a long process of trial and error. ๐ Often, if you switch models, you also have to change the prompt. ๐ฉ What if you could automate this process?
๐ก That's where DSPy comes in - a framework designed to algorithmically optimize prompts for Language Models. By applying classical machine learning concepts (training and evaluation data, metrics, optimization), DSPy generates better prompts for a given model and task.
Recently, I explored combining DSPy with the robustness of Haystack Pipelines.
Here's how it works: โถ๏ธ Start from a Haystack RAG pipeline with a basic prompt ๐ฏ Define a goal (in this case, get correct and concise answers) ๐ Create a DSPy program, define data and metrics โจ Optimize and evaluate -> improved prompt ๐ Build a refined Haystack RAG pipeline using the optimized prompt
