Flux 2 Klein for game art

Fast, cheap and clean. The default for game sprites.

Flux 2 Klein is a small, fast version of Black Forest Labs’ FLUX.2. In Voidless it is the default model: it costs 1 credit a picture and usually answers in a few seconds, so it is the one to draft with.

It draws clean, readable characters and items with simple shapes, which is what most game sprites need. For pixel art, the picture is drawn at full size and snapped to the pixel grid with a limited palette.
