]What FLUX 3 Image Does Well
One model for generating and editing images, at up to 4K.
Native 2K and 4K Output
FLUX 3 Image renders at the size you pick instead of upscaling afterwards. 4K is about 16 megapixels, for example 5456 x 3072 at 16:9, so small text and fine texture hold up when you zoom in.
Up to 10 Reference Images
Upload as many as ten photos and refer to them in order in the prompt as ref_image_0, ref_image_1 and so on. Put a person, a product and a place into one picture.
Bounding-Box Layout Control
Give each element an id, a box on a 0 to 1000 grid and a short description, and add the list to your prompt. Useful for covers, ads and product composites where position matters. Try the Magazine cover example at the top of this page.
Readable Text in Images
Headlines, shop signs, labels and handwriting come out as real words. Put the exact wording in quotation marks.
Edits That Stay Put
Upload a photo and say what to change. In our three-step test the sofa, the wall color and a new plant were changed one after another, and the rest of the room stayed the same.
14 Aspect Ratios, JPEG or PNG
From 21:9 to 1:2, including 16:9, 9:16, 4:5 and 1:1. Download the result as JPEG or PNG.

Frequently Asked Questions
What to know before you run FLUX 3 Image on Veevid.
FLUX 3 Image is the image generation and editing model in Black Forest Labs' FLUX 3 family, released on October 1, 2026. One model handles text-to-image and editing with up to 10 reference images, renders natively at up to 4K, and accepts bounding boxes in the prompt to control layout.
Use the generator at the top of this page: FLUX 3 Image is already selected. Write a prompt or click an example, pick a ratio and a resolution, and generate. Veevid runs the model for you, so there is nothing to install and no graphics card required.
Not yet. Black Forest Labs has said an open-weight version will follow, without giving a date. Until then the model is available through hosted services like this one.
Yes. Download a result, upload it as the next input and edit again. In our test, three edits in a row (new sofa, new wall color, added plant) left the rest of the room looking the same.
Up to 10 per image-to-image request. Refer to them in upload order as ref_image_0, ref_image_1 and so on, for example "the man from ref_image_0 wearing the jacket from ref_image_1". Use only the references you need.
Add a JSON list to your prompt where each element has an id, a bbox written as [y_min, x_min, y_max, x_max] on a 0 to 1000 grid, and a description. The grid is the same for every aspect ratio. Click the Magazine cover example at the top of this page to load a full prompt you can edit.
1K, 2K and 4K, in 14 aspect ratios: 21:9, 2:1, 16:9, 3:2, 7:5, 4:3, 5:4, 1:1, 4:5, 3:4, 5:7, 2:3, 9:16 and 1:2. A 4K image is about 16 megapixels, for example 4096 x 4096 or 5456 x 3072.
No. FLUX 3 Image makes still images. To animate one, download it and use Image to Video on Veevid.
FLUX 3 Image is priced by output size, so the cost depends on both resolution and aspect ratio: 10 or 20 credits at 1K, 39 or 48 at 2K, and 154 or 164 at 4K. Editing costs the same as generating, and reference images do not add to the price. The exact cost is shown before you generate.
