MiniMax H3 Pruned on 32 GB of VRAM
Yes. Q8_0 fits on 32 GB with 4.6 GB to spare. An official, smaller cut of MiniMax H3 published by Comfy-Org, made for cards that cannot hold the full 33B model.
Take Q8_0 (21.6 GB). In use it comes to about 27.4 GB, with 4.6 GB left over on 32 GB.
Got an RTX 40 or 50? Swap Q8_0 for FP8 (21.0 GB): same quality class, computed natively there.
