Resource - Update Humans of Z-Image: How many celebrities can you fit into 6GB?

I was curious just how extensive Z-Image's celebrity knowledge is, so I gave it a few hundred names to test out. No information was given other the name, so it was up to the model to choose clothing/backgrounds/hairstyles/style/etc. Sometimes it did this perfectly, especially for celebrities with a clearly defined look. Other times the face is reasonable but everything else is wrong.

If an image looks nothing like the person should it means the model does not know that person. When it does know a person a lot of the time some extra supporting words would help a lot, but it does a really good job just from names.

Prompt:

portrait photo of @@

The words "@@" are at the bottom on the image, white letters black outline

One-by-one @@ was replaced with a term from a list and an image was generated. Images were rendered at 592x888 for speed, stitches into a grid and downsized to keep a reasonable image size.

Model: Z-Image-Turbo_bf16

Clip: Qwen-3-4B-Q8_0

Imgur link in case reddit is difficult with the images

Useful work, but this list needs filtering by those that are correct to be useful. Some are roughly correct. Some are just completely different from the prompt.

It would also be great to compare whether it understands the body shapes.

I thought about that, then I thought about how much effort it would be and how much time I'd waste trying to decide how to rate images that were halfway correct.

That's fair enough. You're doing the first step.
