FLUX 1.1 Ultra is Black Forest Labs' high-resolution image generation model designed for creators who need 2K photorealism without sacrificing speed. It generates detailed, compositionally precise images in roughly 10 seconds, making iteration fast enough for real-time creative work and production cycles.

Why creators choose FLUX 1.1 Ultra

2K resolution at exceptional speed

FLUX 1.1 Ultra generates 2K images in around 10 seconds, more than twice as fast as competing high-resolution models. That speed fundamentally changes your workflow. You can explore variations and iterate on compositions without long waits. For commercial production timelines and art direction, that's transformative. You're not waiting for renders. You're creating in real time.

Precise composition and prompt adherence

The model reads your prompt with high fidelity. Specific direction like "close-up of a hand holding a pen, shallow depth of field, warm window light" translates directly into the image. You get what you ask for rather than a model's loose interpretation. That precision matters when composition is non-negotiable.

Two photorealism modes for different aesthetics

Ultra mode optimizes for composition, detail, and precision, ideal for commercial visuals, product shots, and art direction. Raw mode captures the feel of candid photography, with a less synthetic aesthetic and more natural imperfections. Toggle between them to shift the look and feel without regenerating. Ultra mode is tighter and more controlled. Raw mode is looser and more organic.

Flexible aspect ratios for any format

Eight aspect ratios from 21:9 cinematic to 9:16 vertical let you generate for any format natively. Social media, print, web hero images, vertical video, vertical stories. No cropping, no aspect ratio compromises. Each generation is composition-native for your intended use.

How to use FLUX 1.1 Ultra in Craze

You describe the 2K image and Craze generates it at high resolution.

1. Start a project and describe the image you want. Be specific about lighting, composition, and mood. "Overhead shot of a cluttered desk in harsh afternoon light" is more actionable than "messy desk."
2. Ask for FLUX 1.1 Ultra and choose your aspect ratio.
3. Craze generates the 2K image in roughly 10 seconds. Review the result in the editor.
4. Regenerate to explore a new variation. Since generation is fast, you can iterate through multiple interpretations rapidly.

Who FLUX 1.1 Ultra is for

Commercial and advertising production

Product shots, lifestyle images, and campaign visuals need precise composition and fast iteration. FLUX 1.1 Ultra delivers both at 2K resolution, ready for print and digital campaigns. Art directors appreciate the speed.

Art direction and creative concepting

Directors and art directors can iterate on visual concepts rapidly. The fast generation and high prompt adherence let you explore compositional variations, lighting changes, and mood shifts in minutes rather than hours. That speed enables real-time feedback loops during creative sessions.

Print and large-display visuals

Billboards, packaging, and print work need high resolution and fine detail. 2K native generation ensures images hold detail at large scale without upscaling artifacts. The resolution and composition precision support print production requirements.

Web and social media at scale

Generate hero images, social media content, and web assets at 2K resolution. The speed means you can generate multiple variations and aspect ratios for different platforms in less time than other high-resolution models require for a single image.

FLUX 1.1 Ultra vs FLUX.2 Pro

Both are from Black Forest Labs but optimized for different priorities. FLUX 1.1 Ultra generates at 2K resolution with emphasis on composition and speed. FLUX.2 Pro generates at 1K and supports reference images for style consistency, making it better for batch creation with unified branding. FLUX 1.1 Ultra is the pick for single hero images where precision and resolution matter. FLUX.2 Pro with references is more efficient for generating multiple on-brand variations where consistency across a batch is the goal. Choose FLUX 1.1 Ultra for hero images. Choose FLUX.2 Pro for batch work with references. For photorealistic depth, FLUX.2 Realism offers different strengths at a different resolution.
