This is the LCM line of ICBINP XL. The awesome photorealism you love, with the speed of LCM.

Doing the sample images for this on a Runpod A5000, four 832x1216 images without hi-res fix was taking 11 seconds, and with hires fix (R-ESRGAN-x4+ at 1.5x) was taking 47 seconds.

This NEEDS the LCM sampler (available from sd-webui-AnimateDiff extension in A1111), and goes best with 6-8 steps, 1.5 - 2 CFG, hi-res fix of 5-10 steps with a R-ESRGAN/4x-Ultrasharp/NKMD-Siax style upscaler at a denoise of 0.3-0.5, and can do resolutions from 512x640 up to stock SDXL 832x1216 without issues.
