MiniMax's first text-to-image model, available on its API platform since February 2025. It renders one to nine images per request at fixed aspect ratios or a custom size between 512 and 2048 pixels.
Pick it if
you want several images from one prompt, up to nine per request
you need a fixed aspect ratio from 9:16 to 21:9
you want to set an exact width and height for the output
Skip it if
you need to edit or reference an existing image; this lane takes a text prompt only
FLUX.2 [klein] is Black Forest Labs' fastest FLUX.2 tier: 4-step distilled open-weight models in 4B and 9B sizes, which BFL says generate in under a second on consumer GPUs. It is the cheapest FLUX.2 face here, below Pro, Flex and Max.
Pick it if
you want the lowest-cost FLUX.2 image in the lineup
you generate high volumes; BFL positions klein for real-time use
you want a model whose weights you can also run yourself
Skip it if
you need maximum FLUX.2 fidelity; FLUX.2 Max targets that
you need fine control over steps and guidance; Flex exposes those
