According to God of Prompt (@godofprompt), differential prompting is an advanced prompt engineering technique where engineers request two AI-generated outputs, each optimized for different criteria, and then select or merge the best features. This approach leverages large language models' capabilities to produce diverse solution strategies, enhancing workflow efficiency and solution quality. For example, generating two versions of a function—one for speed and another for memory efficiency—enables engineers to optimize for specific business requirements or technical constraints. This technique is particularly valuable for AI-driven software development, allowing businesses to tailor AI solutions for performance or resource limitations, leading to more robust and adaptable AI applications (source: @godofprompt, Dec 10, 2025).
