Programming—not prompting—language models

⭐ 38k+ stars 📜 Open Source 🏷️ skill

Overview

Programming—not prompting—language models

✓ Enables systematic optimization of LLM pipelines without manual prompt engineering
✓ Supports local model execution with data privacy and no external API dependencies
✓ Provides low-level control over quantization and model serving configurations
✓ Integrates multiple LLM providers through unified programming interface

✗ Steeper learning curve than prompt-based tools; requires programming expertise and understanding of DSPy framework
✗ Smaller ecosystem and community compared to established prompt engineering platforms
