This is a flux2-klein experiement, the original model can restore images on its own but i found it lacked alot of things like adding new detail thus this lora, this was trained on alot of high quality images + heavily compressed jpeg pairs and also slightly blured images, its good at heavy jpeg compression, and light to heavy blur, it adds back high frequency detail detail, removes soft edges, it may color balance a little,

Can generate very large images aswell 4MP,
IMPORTANT / Keep in mind

  • Use the fast variant with 4 steps, the more steps you add the more detail itll have but max 12, i find youll get way better result with 4 steps and not 20 or more with the base model

  • It dose work well with normal quality images, light and heavy jpeg compression, blur, its very good at keeping faces

  • Was trained on a variaity of images but mainly of men
