Simply doesn't work. I've paid, uploaded 33 training images, it did something for 60 minutes - and generated two multi-gigabyte files. Absolutely unclear what to do with that.
Astria is a very easy and effective way to set your custom model ckpt. and import it to your own Stable Diffusion model. This is going to be the next step in the AI world so far: highly customized subject matter with consistency.
Terribly disappointing. Uploaded 20 images but the software didn't generate any quality images. The only thing I can think of is that I didn't supply sufficient diversity in the backgrounds, but it seems a one-off experience, so wasted my money.
