Summary
Riley Brown puts GPT Image 2.0 through a series of hands-on experiments on the day of its April 21, 2026 release. One of the more remarkable tests involves generating book cover images with functional barcodes: Brown generates covers for “Good to Great” and “The Intelligent Investor,” scans the barcodes with a physical scanner, and confirms they resolve to the correct titles — even after masking the visible ISBN number to rule out OCR as the explanation.
Brown also tests multi-edit prompting, issuing 11 simultaneous edit instructions on a cartoon self-portrait and tracking each against the output. He walks through every result in sequence, demonstrating high instruction-following accuracy across changes like text overlays, color swaps, object removal, and background edits. The video covers the basics of getting started with GPT Image 2 inside ChatGPT, including the image UI, the select tool for targeted regional edits, and generating iPhone app mockups from multiple screenshots.
In the final section, Brown integrates GPT Image 2 with OpenAI’s Codex agent application, enabling parallel image generation through an agent workflow rather than the sequential chat UI. Practical use cases covered include personalized magazine covers, photorealistic portraits from reference photos, and multi-image product mockups for mobile app store listings.
