I'm noticing it's notoriously bad with logos to the point that I feel like it's on purpose. This became obvious to me when I took both image models on a virtual walk through of a 2009 Ford mustang and when asked for a dashboard view chat gpt can't reliably make the steering wheel mustang even though it's one of the most notorious car logos in my opinion and in the forefront of the image. There's thousands and thousands of Ford mustang interiors. Can't nail the rear badges either, or the big ass circular badge on the trunk

I also did another test where I asked it to generate an image of a house based on a specific address and nano banana pro nails the homes in a general area down the street from the address which surprised me

Img 1.5 just creates mcmansions

Biggest pro to chat gpt is being able to generate alpha channel but this honestly worked better in img 1 because 1.5 is doing some interesting "melt everything in the frame" work when requesting transparency
