## API or self-hosting?

- **API**: no GPU, pay per image, includes prompt upsampling and pixel restoration; allowed for companies of any size.
- **Self-hosting**: free weights, but you pay for GPUs, storage and upkeep — and companies with $5M+ revenue need a commercial license from BFL ([license guide](https://imageklein.com/flux-3-image-klein-license)).
