Loop engineering is just prompt engineering with great system design.

Loop engineering refers to an iterative approach to AI system design that combines prompt engineering with robust system architecture, emphasizing that effective AI applications depend equally on how prompts are structured and how the overall system is designed to handle them. This concept, shared by DAIR.AI, suggests that successful AI engineering goes beyond crafting individual prompts to include comprehensive system-level considerations that create feedback loops and optimize performance across the entire pipeline.
