black-forest-labs/flux-3-imagePhotorealism up to 4K, and editing from 10 references
FLUX 3 is Black Forest Labs' flagship image model, released on 1 October 2026. It generates from text and edits from up to 10 reference images in the same model.
On the Artificial Analysis text-to-image board it scored an Elo of 1116 on 17 October 2026, against 1003 for FLUX.2 Pro. Skin, fabric and light read as photographs. On Tchavi it renders at four fixed sizes, 1K, 1.5K, 2K and 4K, each with its own price, and every aspect ratio from 21:9 to 9:21.
On Tchavi you pay with mobile money, no card and no KYC. One API key opens 90+ models, images and video included: compare FLUX 3 with the others on the same prompt.
