Frequently Asked Questions

FLUX 1.1 Pro Ultra generates native 4-megapixel images up to 2K resolution in roughly 10 seconds without requiring secondary upscaling passes or high-resolution fix workflows. Built on a 12-billion parameter flow-matching transformer with a T5-XXL text encoder, it synthesizes fine photographic details and accurate scene text natively.

Raw Mode creates authentic, DSLR-style photographs by neutralizing the synthetic gloss and oversaturated highlights typical of AI generators. It introduces natural analog grain, lifelike skin pores, and soft dynamic range. Keep Raw Mode enabled for candid portraits and documentary visuals, and disable it when aiming for polished 3D renders or studio commercial campaigns.

No, FLUX 1.1 Pro Ultra does not support negative prompt inputs due to its underlying architecture. To steer outputs, describe your desired elements, camera specs, and photographic style directly in natural, conversational English within the main prompt.

The model supports seven aspect ratios ranging from cinematic ultra-wide (21:9) and landscape (16:9) to standard (4:3), square (1:1), portrait (3:4), tall (9:16), and ultra-tall (9:21). Images can be exported as PNG to preserve high-frequency skin textures and text details, or as JPEG for lightweight file sizes.

The model excels at candid lifestyle photography, high-fashion editorial portraits, commercial print assets, cinematic concept frames, and scenes requiring legible typography. It is less suited for stylized flat 2D vector graphics or complex anatomical poses with heavily tangled limbs.
