FLUX.1 Krea [dev] is currently restricted to non-commercial use under the FluxDev Non-Commercial License. Individual users are free to use the generated images for artistic creation, academic research, etc., but any commercial monetization of the generated content (including, but not limited to, advertisements, product packaging, digital content sales, etc.) requires a separate formal license from Black Forest Labs. Commercial users may request a commercial license through the contact information provided on the Hugging Face page, which will ensure the legitimacy of their use and may result in additional technical support.
