FLUX 3
by Black Forest Labs
Black Forest Labs' newest family: images up to 4K, and video with sound.
What it is
FLUX 3 is the newest generation from Black Forest Labs, and in this Studio it covers both stills and motion. The image model is described as "Black Forest Labs' newest image model", made to "generate detailed, well-composed images in native 2K and 4K with precise layout control and improved text rendering".
Its edit endpoint "makes precise local edits without changing the rest of the image, and combines up to 10 references into one balanced, well-composed result". That makes it the model to reach for when a product, a face and a location all have to end up in one frame.
On the video side, FLUX 3 is "Black Forest Labs' frontier video model". Here it makes clips from a prompt or from a still, extends a clip you already have, edits a clip on instruction, and fills the move between a first and a last frame, at 720p or 1080p and up to twenty seconds, with sound.
What it is good at
Resolution is part of the model, not an upscale afterwards. You pick 1K to explore and 4K for the final, and the Studio shows the price of each before you run.
Product, model, set and light from separate images, combined into one composition. The rest of the image stays as it was.
A still made here and a clip made here come from the same lab, so the look carries over from the image to the video.
Longer than most video models in the catalogue, with sound generated alongside the picture.
Where it struggles
- Black Forest Labs publishes no list of limitations for FLUX 3, so none is invented here.
- There is no LoRA support yet. For your own trained style, FLUX.2 with a LoRA stays in the Studio.
- The image price grows with resolution: 4K costs many times 1K. The Studio shows the amount on the button before you run.
- FLUX 3 cannot extend an image beyond its edges. For that, the Studio keeps FLUX.2 Outpaint.
How to prompt it
Describe the composition as well as the subject: where things sit in the frame, what is large and what is small, where the text goes. FLUX 3 is built for layout control, so a prompt that says "headline across the top third, product centred below it" gets used. For video, describe the movement and what the camera does, in the order it happens.
An example that shows what that means
A ceramic coffee cup on a pale oak table, centred in the lower half of the frame, soft window light from the left, the words "MORNING RITUAL" in a thin serif across the top third, generous empty space around both.
What we offer here
Straight from the catalogue, so this list never goes stale. The price is the provider’s published rate with our markup on top, and it is on the button before you run anything.
Questions
Which FLUX should I use, 2 or 3?
FLUX 3 for new work. FLUX.2 stays for one thing: running your own LoRA, which FLUX 3 does not support yet.
Can it make a video from just a prompt?
Yes. FLUX 3 makes video from text, from a still, between a first and a last frame, and it can extend or edit a clip you already have.
Why does 4K cost so much more than 1K?
Black Forest Labs charges per megapixel, and a 4K image has about sixteen times the pixels of a 1K image.
What happened to FLUX.2 Pro?
FLUX 3 replaced it in the Studio. Flows you built with FLUX.2 Pro open with FLUX 3.
