Emergence of Loop and Graph Engineering as Higher-Level Abstractions Beyond Prompt Engineering
Other Provisional 45% confidence first seen
Industry practice has established three hierarchical layers of AI system control: prompt engineering (controlling single model responses), loop engineering (automating agent decision cycles, emerged late 2025), and graph engineering (coordinating multiple agents in parallel, emerged mid-2026). Each layer operates at a different scale of abstraction, with loop engineering requiring mechanical stop conditions and graph engineering making multi-agent systems more programmable through organizational structure.
