Your First Steps into DSPy: Building AI Without Manual Prompts
You’ve seen why prompt engineering is brittle. But how do you actually start coding with DSPy? Is it complicated? Does it need a huge setup?
This article explains the fundamentals of using DSPy, a programming framework designed for building AI systems without the need for manual prompts. It covers installation, signature creation, and module implementation, demonstrating how to efficiently declare what inputs are required and what outputs should be expected. Readers are guided through the process of creating straightforward DSPy programs, learning about advanced techniques like multi-modal signatures and the importance of modules as building blocks of reasoning, ultimately encouraging a transition from prompt engineering to systematic programming for complex AI tasks.
