It worked consistently well at the size of a sheet of paper, 8.5” x 11”. Advances now enable consistent realism at the 4x the size, a poster, 17”x22”.

Also this takes 15 minutes, down from 2 hours a month ago. Ultimate SD Upscale takes 10 hours. (tested on RTX 3090, Xformers enabled)

Gigadiffusion LoRA : Gigadiffusion now has a LoRA! It was trained on gigapixel scans of famous artwork and optimizes diffusion’s focus on stunning, true to life, detail and texture.

Illuminati Diffusion: based on SD 2.1 768, it is a massive step forward. However, itt has challenging upscaling. When combined with the LoRA and an extreme negative prompt, the results are outstanding.

Combining these increased quality, permitting removing steps of the workflow. Those steps add up to an 8x theoratical speedup on paper, matching the data.
