Not in my experience. I asked nb to create a transparent rectangle shape and gave it RGB hex for the fill. It created the box but put the hex as text inside of it and used a checkerboard for its background. When I told it that the image wasn't transparent, it wouldn't budge!

Oh yeah, they don't know what "transparent" means. Most of them generate the Photoshop checkerboard background. They also don't know "upside-down".

There isn't much R&D going into image models and what you're getting is scraps from labs that care more about other things. NBP is the closest to a reasoning image generator we have.
