The page names four tiers — Builder ('FLUX.2 [klein] models, 10K images/month, 1 domain, 10 licensed users, Fine-tuning & LoRA rights'), Platform ('FLUX.2 [klein] Base 9B + FLUX.2 [dev], 100K images/month'), Professional ('for agencies and service providers') and Enterprise — differentiated by monthly image quota, domain and user counts; Builder, Platform and Professional carry a 'Purchase' CTA with no sticker price, Enterprise is Contact Sales. The fifth 'Synthetic Data' tier was not on the page on 2026-09-04 or 2026-09-05.

Same page: the licence covers self-hosting and fine-tuning ('Fine-tuning & LoRA rights') of FLUX open-weight models on the licensee's infrastructure; 'Not meant for client use or downstream applications' on Builder is what separates the tiers.

image-generation (FLUX is an image model family) and model-training ('Fine-tuning & LoRA rights' on every tier). The product IS a licence, and the vocabulary has no model-licensing term — ip-licensing is defined as silicon designs, so it was removed from the batch's list. Tagged with the two true terms rather than minting a new one, the same treatment as the licensed-datasets gap on appen-ots-datasets and toloka-datasets.

Live re-check 2026-09-15: the licensing page contrasts "An API gets you started. Weights give you control" — describing a relationship between the two access modes rather than confirming the licence is sold independently of a parent offering.
