FLUX 3

Black Forest Labs' newest generation and editing model

Try FLUX 3

FLUX 3 is the image model Black Forest Labs released in October 2026, the successor to FLUX 2. One model handles both text-to-image generation and editing, and it can take several reference images at once.

Write a prompt to create something new, or upload photos and describe the change. On AirGallery it costs the same as Nano Banana 2, so it's easy to compare the two on one prompt.

Sample images

FLUX 3: A photo of a white ceramic coffee mug on a wooden cafe table next to a rain-streaked window, soft morning light. The mug is printed with the words "Good Morning" in black hand-lettered script.
