What Flux is for
Flux from Black Forest Labs is a text-to-image model. You describe the frame and it returns a still image in about 10 seconds, billed at Credits. This page groups 7 modes (FLUX 1.1 [pro], FLUX 1.1 [pro] (ultra), FLUX.1 [pro] Fill, FLUX 1.1 [pro] (ultra) Redux, FLUX 1.1 [pro] (ultra) Fine-tuned, FLUX.1 [pro] Fill Fine-tuned, and FLUX 1.1 [pro] Redux) so you are not hunting separate URLs for the same family.
Flux is cheap enough that a generation usually fits the free Knowlify plan's credits. A typical run is about 10 seconds.
Pick Flux for text to image at Credits and ~10s. Compare it with Flex, Flux 1, Flux 2 Klein on the related cards below if you need a different look, speed, or input type.
How to use Flux
- 1. Upload the still Flux should start from, then write the change or motion in Input.

- 3. Stay in the studio if you want that frame or clip inside a longer narrated video.
What you need
- A prompt that names the subject, style, and framing.
- A source still (PNG or JPG) for the model to start from.

Frequently asked questions
How do I run Flux?
Run Flux on Knowlify at /generate/flux. This page has 7 modes in one dropdown. Write the prompt on this page and it opens in the studio, where Flux generates a still image. The same studio also turns documents into full narrated videos.
Where can I use Flux online?
On Knowlify (Black Forest Labs's model, knowlify.com/generate/flux). You do not need a separate playground. Flux runs in the studio next to document-to-video.
Can I make a longer video with Flux?
Flux itself produces a still image. On Knowlify you can take that output, or skip it and upload a document, and generate a full narrated video with a script you can edit.
What do I need to run Flux?
A prompt and a source still. Flux will not invent the starting frame for you on this mode.
How long does Flux take?
Plan on about 10 seconds for a typical run, then whatever queue time the studio has. Video models sit at the high end of that range.
Does Flux have more than one mode?
Yes. This page has 7 modes: FLUX 1.1 [pro], FLUX 1.1 [pro] (ultra), FLUX.1 [pro] Fill, FLUX 1.1 [pro] (ultra) Redux, FLUX 1.1 [pro] (ultra) Fine-tuned, FLUX.1 [pro] Fill Fine-tuned, and FLUX 1.1 [pro] Redux. Switch them in the Mode dropdown instead of opening a new URL.
What does FLUX1.1 [pro] cost?
Knowlify charges this as credits, at the compute cost.
What is FLUX1.1 [pro] best for?
FLUX1.1 [pro] is an enhanced version of FLUX.1 [pro], improved image generation capabilities, delivering superior composition, detail, and artistic fidelity compared to its predecessor. It turns a text prompt into an image.
Do I need an account to use FLUX1.1 [pro]?
You need a Knowlify account to run FLUX1.1 [pro], and signing up is free. Your prompt carries across.
