I have been finetuning a 256x256 resolution diffusion model for about a week and a half, it is currently well above a million training cycles. For reference most small models are usable in about 1000-2000 cycles, this is extreme overkill but I keep adding to the dataset.
This is the first in a series of floral studies created using this custom diffusion model (I'm calling it "Kompromat Diffusion") and my own work in Photoshop. This output has then been upscaled to 4K using ESRGAN with a somewhat obscure model.
This second image was a product of running "crocus_study1" back through the model again to further refine its' output. You will notice that the color palette has become more muted and there are some small refinements to the image that I personally enjoy.
