Short answer: often yes, but the answer depends on which FLUX model made the image and where you ran it. The three main FLUX.1 variants ship under different terms, and the details are easy to get wrong. This is a plain-language guide, not legal advice, so read the current license text for anything high-stakes.
The Short Answer
| Model | License type | Commercial use of outputs |
|---|---|---|
| FLUX.1 Schnell | Apache 2.0 | Yes, the license permits commercial use |
| FLUX.1 Dev | Non-commercial license for the model weights | Outputs are treated differently from the model itself; read the outputs clause |
| FLUX.1 Pro | Paid API / commercial agreement | Yes, under the terms of the service you use |
Black Forest Labs, the company behind FLUX, publishes the license text for each model. Terms and newer model releases can change, so confirm against the current license before you build a business on it.
FLUX.1 Schnell: The Simple One
Schnell is released under Apache 2.0, a permissive open-source license. You can run it yourself and use what it generates commercially. It is also the fastest model, trading some detail for speed. See FLUX Dev vs Schnell for how the quality compares.
FLUX.1 Dev: Read the Outputs Clause
Dev’s weights are released under a non-commercial license. That restriction is about the model: using the weights in a paid product, for example hosting Dev as a service you charge for, needs a separate commercial license from Black Forest Labs.
The license also has a clause about outputs, the images you generate. As published at the time of writing, it says the license does not claim ownership of outputs and allows you to use them, including commercially, subject to the license’s other conditions (for example, not using outputs to train a competing model and not breaking the law). Because the wording matters, read that clause yourself rather than relying on a summary, including this one.
Where you run Dev matters too. If you use Dev through a hosted service, that service’s own terms usually govern what you can do with the images.
FLUX.1 Pro: Commercial by Design
Pro is offered through an API and partner platforms rather than as downloadable weights. Commercial use is the point of the product, but again the platform’s terms apply. Check them for restrictions on resale, attribution, and prohibited content.
Beyond the License: Other Risks
A model’s license is not the only thing between you and a safe commercial use:
- Likenesses and trademarks. Generating a real person’s face or a brand’s logo can raise legal issues regardless of the model’s license.
- Copyright of AI output. Whether purely AI-generated images can be copyrighted varies by country. Do not assume you can stop others from copying them.
- Platform rules. Stock sites, print-on-demand shops, and ad platforms each have their own policies on AI-generated work.
- Client contracts. If you deliver images to a client, tell them how they were made and check what the contract requires.
For a business-focused look at practical uses, see AI image generation for business.
A Quick Checklist
- Note exactly which model and version generated the image.
- Open that model’s current license and read the outputs section.
- If you used a hosted service, read its terms too.
- Keep a record of the prompt, model, and date.
- When in doubt, ask a lawyer, especially before selling at scale.
If you want to generate images without setting up models yourself, try the AI image generator and review the terms for the plan you use. For running Dev locally, see the FLUX.1 Dev ComfyUI workflow.
Frequently Asked Questions
Can I sell images made with FLUX.1 Dev?
The Dev license restricts commercial use of the model but addresses outputs separately. Read the outputs clause in the current license before selling, since the details matter.
Is FLUX Schnell free for commercial use?
Yes. It uses the Apache 2.0 license, which permits commercial use.
Do I own the images I generate?
Licenses generally do not claim ownership of outputs, but whether AI-generated images qualify for copyright protection depends on your country.
Do I need to credit Black Forest Labs?
Check the license for the model you used. Apache 2.0 has its own notice requirements for redistributing the software, which differ from simply using outputs.
Does this apply to other FLUX versions?
Newer releases may use different terms. Always read the license that ships with the specific model you use.
