Abiray/MiniMax-H3-Pruned-Ref-Delta-Fused-GGUF

MiniMax-H3 Pruned Ref-Delta Fused (GGUF)

GGUF quantizations for xmarre's MiniMax-H3-Pruned-Ref-Delta-Fused-r1024-ComfyUI.

This hybrid model fuses the crisp visual quality, motion dynamics, and clean audio of FL2VA with the persistent multi-image character conditioning of Ref2VA using a rank-1024 delta weight merge ($\Delta W_{r=1024}$) on the pruned 20.1B parameter MiniMax-H3 architecture.

With these GGUFs, you can now run reference-conditioned MiniMax-H3 locally on consumer GPUs (16 GB – 24 GB VRAM) with minimal quality loss.
