FLUX 3 Image
The image part of Black Forest Labs' FLUX 3 multimodal family (which also covers video and robot actions). It adds a bounding-box layout system, multi-reference composition and native 4K output. It is the highest-ranked FLUX model on Artificial Analysis.
Best for
Layout-controlled images where you place each element with bounding boxes, at native 2K or 4K.
Overview
The image part of Black Forest Labs' FLUX 3 multimodal family (which also covers video and robot actions). It adds a bounding-box layout system, multi-reference composition and native 4K output. It is the highest-ranked FLUX model on Artificial Analysis.
Strengths and limits
- Bounding-box layout control and targeted per-box editing
- Up to 10 reference images in one composition
- Native 2K and 4K output without separate upscaling
- Not open weights; commercial self-hosted weights only via sales
- 4K images cost far more than lower resolutions
