About

A new high-resolution capabilities to FLUX1.1 [pro], extending its functionality to support 4x higher image resolutions (up to 4MP) while maintaining an impressive generation time of only 10 seconds per sample.

Higher Resolution, No Compromise in Speed

FLUX1.1 [pro] – ultra mode: This option enables image generation at four times the resolution of standard FLUX1.1 [pro], without sacrificing prompt adherence. Unlike many high-resolution models that experience significant slowdowns at higher resolutions, our performance benchmarks show sustained fast generation times—over 2.5x faster than comparable high-resolution offerings. This model is available at a competitive price of $0.06 per image.

Raw Mode

FLUX1.1 [pro] – raw mode: For creators seeking authenticity, our new raw mode captures the genuine feel of candid photography. Toggle this feature to generate images with a less synthetic, more natural aesthetic. Compared to other text-to-image models, raw mode significantly increases diversity in human subjects and enhances the realism of nature photography
