## Notes

Previous generation (BFL pricing page lists FLUX.1 as 'previous generation'); still served. Release date from memory of BFL launch (May 2025), not re-verified today. Also still served: flux-pro-1.1 ($0.04), flux-pro-1.1-ultra ($0.06).

Previous-gen FLUX editing models; for new work prefer FLUX.2 [pro]/[max].
