The 20s on 20 Project
This is a comparison of images made by twenty different AI models, all using the same prompt... one featuring a 1920s model. Different prompts work better on different models, so take it with a grain of salt.
The model is the relatively unknown Ideogram 0.2. They haven't said publicly that I have seen, but Ideogram seems to run on an entirely different ecosystem... meaning that it's not Stable Diffusion or Dall-E but something else entirely. (There is already an Ideogram 1.0, but I don't think the results are quite as good for this particular prompt.)
Of all the models, I think this one did the best job at making what looks like it could be a real painting. It's not perfect -- there is something odd going on with the sleeves, for instance -- but I like it.
