Pro, Flex and Max land on almost the same frame. Klein and FLUX.2 each find their own, and Klein's tubes look like candles.

Photograph of a radio repairer in her thirties with short black hair and round glasses, soldering inside an open 1960s tube radio at a cluttered workbench. A warm desk lamp lights her hands and the glowing tubes, thin smoke curls from the iron, and shelves of spare valves and tools fade into shadow behind her. Shot on a 50mm lens at f/2.8, natural skin texture, fine film grain.

What is FLUX.2?One family, five models.

FLUX.2 is the second family of image models from Black Forest Labs, after FLUX.1. Every model in it makes images from a text prompt and edits the images you give it.

The five differ in what they cost, how many reference images they take, and which settings they let you change. Klein and FLUX.2 are for drafts. Pro, Flex and Max are for finals.

All five sit in the same image tool. Switch models and run the same prompt and seed again.
