I’ve noticed, at least with the model I occasionally use, that the best way I’ve found to consistently get western eyes isn’t to specify round eyes or to ban almond-shaped eyes, but to make the character blonde and blue eyed (or make them a cowgirl or some other stereotype rarely associated with Asian women). If you want to generate a western woman with straight black hair, you are going to struggle. I’ve also noticed that is you want a chest smaller than DDD, it’s almost impossible with some models — unless you specify that they are a gymnast. The model makers are so scared of generating a chest that could ever be perceived as less than robustly adult, that just generating realistic proportions is impossible by default. But for some reason gymnasts are given a pass, I guess. This can be addressed with LORAs and other tools, but every time you run into one of these hard associations, you have to assemble a bunch of pictures demonstrating the feature you want, and the images you choose better not be too self-consistent or you might accidentally bias some other trait you didn’t intend to. Contrast a human artist who can draw whatever they imagine without having to translate it into AI terms or worry about concept-bleed. Like, I want portrait-style, but now there are framed pictures in the background of 75% of the gens, so instead I have to replace portrait with a half-dozen other words: 3/4 view, posed, etc. Hard association is one of the tools AI relies on — a hand has 5 fingers and is found at the end of an arm, etc. The associations it makes are based on the input images, and the images selected or available are going to contain other biases just because, for example, there are very few examples of Asian woman wearing cowboy hats and lassoing cattle. Now, I rarely have any desire to generate images, so I’m not playing with cutting edge tools. Maybe those are a lot better, but I’d bet they’ve simply mitigated the issues, not solved them entirely. My interest lies primarily in text gen, which has similar issues.
