How the Test Worked: Gemini Reverse-Engineered Briefs, Sora 2 Rebuilt 10 Brands' Ads

petesena · x · 2026-11-04

petesena explains the setup: Ipsos and Syracuse's Newhouse School took real :30 ads from 10 brands (Cheerios, Fiat, H&M, Visa, etc.), all made before 2021. Gemini reverse-engineered each brief and wrote a shot list; Sora 2 then produced the AI version with no human creative involved.

This brief-matching pipeline makes the human-vs-AI comparison fair—both versions came from the same brief—making it one of the more rigorous AI ad quality tests.
