How to run it

On your own serverWeights are downloaded from Hugging Face and served with vLLM (load and API) or llama.cpp (modest hardware). The model then runs in a closed network with no per-request fees.Hugging Face

I can set this up end to end: pick the model size, deploy it on your server and connect it to your systems. Quantization compresses a model so it takes less video memory and runs on more modest hardware. Answers change slightly, so quality is checked on your own examples.

Frequently asked questions

Can FLUX be used in a commercial project?

With conditions. License: FLUX.1 [schnell] and FLUX.2 [klein] 4B: Apache 2.0; [dev] versions: non-commercial. Restrictions vary — region, company revenue, attribution requirements. Have a lawyer check the terms before a commercial launch.

What hardware does FLUX need?

At minimum: One GPU with 16–80 GB — mid-size versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.

Does FLUX support Russian?

Language does not matter for this model: it does not work with text.

Where can I download FLUX and what does it cost?

The FLUX weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
