Prompting tips
Prompts can be loose or detailed. Whether you describe a vibrant comic book splash page of a cyberpunk metropolis or a clean minimalist studio product mockup, Klein interprets the core themes swiftly. Use it to lock down color schemes and layout before scaling up.
Where it fits
In the image suite, select FLUX 3 Klein from the model picker. Choose an aspect ratio from 1:1 square, 16:9 widescreen, 9:16 vertical, 4:3, 3:4, or 21:9 ultrawide at 1K resolution. Click generate and receive rendered stills in seconds.
Controls and pricing
Because Klein is tuned for speed and efficiency, it uses the lowest credit allocation in the FLUX lineup. When an initial concept hits the mark and requires intricate photoreal micro-textures or high-res type rendering, switch to FLUX 3 directly in the picker.
