Ideas for your work
What people get out of Flux 3 Image, by the kind of work they do.
What it is good at
Flux 3 is the newest image model from Black Forest Labs. It generates from text or edits an existing image with reference images, and keeps the parts you didn't ask to change. In Rendair it goes up to 4K.
When to pick it
- You want a sharp, detailed image straight from the model, up to 4K.
- You're editing a render with references, such as a specific material or piece of furniture, and the rest has to stay intact.
- You want a more interpretive, editorial look than a strictly literal render.
What to watch for
- 4K costs noticeably more than 1K. Draft at 1K and render the chosen option at 4K.
- It takes a little over a minute per image, so use a faster model for quick exploration.
- When the render must match a drawing line for line, compare it with Rendair v2.
About Flux 3
FLUX 3 is Black Forest Labs' multimodal model family, announced in July 2026. Black Forest Labs built the image model for instruction-based editing, such as recoloring, moving or swapping objects while preserving the rest of the image, and for combining several reference images in one result.
