Why FLUX 2 Flex is good

Tunable steps and guidance

Black Forest Labs built Flex as the FLUX 2 variant with adjustable steps and guidance, so quality versus speed is a setting, not a different model.

Typography and fine detail

This is the FLUX 2 model they position for text rendering and small details. Headlines, labels, UI chrome, and infographic type are the usual jobs.

Text to image and editing

Generate from a prompt or edit an existing image. Same credit price either way: 3.2 credits ($0.03) per render.

Five aspect ratios

Pick square, portrait, or landscape in the studio: 1:1, 9:16, 16:9, 3:4, and 4:3.

Pay only for keeps

Every render is a free preview. Credits are charged only when you keep a take. Kill the rest and the hold is refunded in full.

Commercial, no watermark

Kept takes download at full quality with commercial use included. No watermark on the file.
