The Verdict
- Detailed prompts gave cleaner product shots but killed creativity.
- Simple prompts let models show personality, good and bad.
- Nanobanana 2 won both, with clean geometry and real proportions.
- GPT Image 2’s 43 to 52 second times are a dealbreaker.
- Weirdest find: both GPT Image 2 and Nanobanana 2 drew exact production bikes.
- We named no brand. They gave us a Specialized S-Works and a Trek for road, a Pivot for the mountain build.
- Is this what AI advertising looks like? Quiet brand placement in results nobody marks as ads?
- Or just training overload on the biggest names. Worth running at scale to see which brands models default to. Paused for now.
Variation 1
Road Bike (Detailed Prompt)
Highly detailed prompt specifying exact geometry, components, and photography style
The Prompt
Create a professional product photography shot showing the perfect side profile geometry of a high-end road racing bike. The bike should be positioned on a clean white or light gray background, perfectly level, showing the complete side view to display: head tube angle, seat tube angle, top tube length, wheelbase, and bottom bracket drop. The bike should be a modern aero road bike with deep section carbon wheels, electronic shifting (visible rear derailleur), and aggressive racing geometry. Lighting should be clean and even with subtle shadows to show depth and tube profiles. No rider, no distractions - pure geometry showcase. Think product catalog photography meets engineering diagram. Shot on medium format camera, tack sharp from front to back, editorial product photography style.

Mountain Bike (Detailed Prompt)
Highly detailed prompt specifying suspension, geometry, and technical details
The Prompt
Create a professional product photography shot showing the perfect side profile geometry of a high-end full-suspension mountain bike. The bike should be positioned on a clean white or light gray background, perfectly level, showing the complete side view to display: slack head tube angle, steep seat tube angle, long reach, short chainstays, and full suspension linkage design. The bike should be a modern enduro/trail bike with 150-160mm travel, dropper post fully extended, 29-inch wheels with aggressive knobby tires, and visible suspension components (fork and rear shock). Lighting should be clean and even with subtle shadows to show the frame's sculpted tubes and suspension design. No rider, no action - pure geometry and engineering showcase. Think product catalog photography meets technical spec sheet. Shot on medium format camera, tack sharp throughout, editorial product photography style.
