This Lora is extraxted from a fine tuned checkpoint, based on Flux dev de-distilled.

This checkpoint has been trained on high resolution images that have been processed to enable the fine-tune to train on every single detail of the original image, thus working around the 1024x1204 limitation, enabling the model to produce very fine details during tiled upscales that can hold up even in 32K upscales. The result, extremely detailed and realistic skin and overall realism at an unprecedented scale.

This first alpha version has been trained on male subjects only but elements like skin details will likely partically carry over though not confirmed.

Training for female subjects happening as we speak.
