The open weights run locally. BFL’s Kommunity License, as they describe it, allows free commercial use under $5 million in annual revenue. Their API post starts at $0.009 per 1K image. Their speed figures are about 4 seconds for a 1 megapixel image on an RTX 5090 and under 9 seconds on an RTX 4070, distilled INT8, through ComfyUI. Full citations: latest AI image models.
