Pruned BF16 MiniMax H3 Models Drop to 40GB Without Quality Loss

marres · reddit · 2026-08-05

Comfy-Org quietly released pruned BF16 checkpoints for MiniMax H3 diffusion models (FL2VA and REF2VA) on Hugging Face.

By using the precomputed AdaLN table variant, which removes about 40% of checkpoint parameters without pruning the main transformer blocks, the model size is reduced from roughly 66.3 GB to 40.2 GB each. This provides a new quality-first option for BF16 users.
