Why FLUX 3 Image Klein matters for businesses
The FLUX Kommunity License allows free commercial use for individuals and companies with annual revenue under $5 million; larger organizations need a self-hosted license or the API. That makes it a practical option for small businesses that want to run image generation on their own hardware, as long as they stay under the threshold.
