Flux 2 Klein - Fast AI Image Generator

Flux 2 Klein is a fast AI image generator from Black Forest Labs. Type a prompt, get a high-quality image in seconds. It also lets you edit images by uploading references and describing changes. Good for both creating from scratch and tweaking existing visuals.

Speed, mainly. It's one of the fastest Flux models out there. Text rendering is solid—logos and words actually come out readable. The multi-reference feature is useful too: upload a few images and the AI keeps things consistent across generations.

Product shots, social posts, marketing graphics, illustrations, UI mockups, character art—pretty much anything visual. Works well for edits too, like swapping backgrounds or restyling a photo while keeping the subject intact.

Yes. New users get free credits to test it out, no credit card needed. If you like it, you can buy more credits later.

Most images come out in a few seconds. Fast enough to try multiple variations without waiting around. Speed depends a bit on server load, but it's generally quick.

Photos you upload to guide the output. Helpful when you want the same character look across images, or need to match a particular style. You can add up to 5 per generation.

Be specific in your prompts—describe the subject, style, lighting, colors. If you want text in the image, type the exact words. Reference images help with consistency. Try small tweaks between generations to dial in what you want.

Just a prompt. Type what you want, hit generate. No setup, no downloads. Add reference images if you need more control.
