FLUX.2 Klein 9B is Black Forest Labs’ larger FLUX.2 [klein] sibling—built for detail-rich, reference-guided 1K drafts. On Cinel the billing registry still lists 0 credits and includes 9B in CINEL_FLUX_UNLIMITED_MODEL_IDS (same FLUX fair-use accounting family as 4B) (observed cinel-pricing). However, the model is internal: true—kept for billing/history and hidden from the public picker after pea delist (observed). It is not today’s public free-queue CTA. For live 0-credit runs, open FLUX.2 Klein 4B (observed public wall). Older “from 2 credits” copy is wrong and must not return.

Compare licenses and size here; generate free on 4B when you need the open queue now.
