Flux by Black Forest Labs has rapidly become the go-to AI image generator for photorealism. Created by former Stability AI researchers, the Flux model family offers different tiers from free open-source to professional quality.

What Makes Flux Stand Out

Photorealism is Flux’s superpower. For product photography, portraits, and realistic scenes, Flux 2 Pro produces images that are genuinely hard to distinguish from real photographs. The open-source Flux Dev and Schnell models make it accessible to everyone.
