The call
17B MMDiT open-weights image foundation, MIT-licensed, SOTA-at-release. Full/Dev/Fast ladder distilled down the step count. The MIT license is a big unlock for production commercial pipelines vs FLUX dev.
When not to use: At 12 GB VRAM — even Fast FP8 reports 16–18 GB. For those budgets, FLUX.2 klein 4B or Z-Image-Turbo are the sane picks. FLUX.2 [dev] still edges it on complex compositions.
Runner notes
ComfyUI. FP8 variants land at ~16–18 GB VRAM; BF16 full wants 20–27 GB. Fast is 1.5–2× quicker than Full at a small quality cost.
