DSPy: Declarative Language Model Programming

Stanford NLP's framework for programming—not prompting—language models.

Quick Start

import dspy

# 1. Configure
dspy.settings.configure(lm=dspy.OpenAI(model='gpt-4o-mini'))

# 2. Define Module
qa = dspy.ChainOfThought("question -> answer")

# 3. Run
response = qa(question="What is the capital of France?")
print(response.answer)

Learning Path (DAG)

The DSPy framework follows a natural progression from core concepts through optimization to advanced applications. Use this directed acyclic graph to understand dependencies and navigate the skill components.

Common Workflows

Workflow 1: Basic QA System

1. Configure LM → Design Signature → Build Module
2. Path: configuring-language-models.md → designing-signatures.md → building-modules.md

Workflow 2: Optimized RAG System

1. Configure LM → Build RAG Module → Optimize with Few-Shot → Evaluate
2. Path: configuring-language-models.md → building-rag-pipelines.md → few-shot-learning.md → evaluating-programs.md

Workflow 3: Production Agent

1. Configure LM → Design Signature → Build ReAct Module → Add Assertions → Optimize Instructions → Evaluate
2. Path: configuring-language-models.md → designing-signatures.md → building-modules.md → assertions-validation.md → instruction-optimization.md → evaluating-programs.md
