Abiray/MiniMax-H3-Singularity-GGUF

MiniMax-H3-Singularity GGUF

GGUF quantized versions of WarmBloodAban/Minimax-h3_Singularity, a community fine-tune of MiniMax H3 specialized in enhanced visual fidelity — HDR clarity, distant-face restoration, cleaner skin, stronger action motion, and improved VFX. These quantizations reduce VRAM requirements for use with ComfyUI, enabling local inference on consumer GPUs.

Recommended Usage

ComfyUI Setup

Place the downloaded .gguf file in your ComfyUI models/unet/ directory (or models/diffusion_models/ depending on your ComfyUI-GGUF fork). You will also need the following components:

Component	Source
Text Encoder	qwen3vl_32b_minimax_h3_Q4_K_M.gguf from Abiray/MiniMax-H3-GGUF
Video VAE	minimax_h3_video_vae_fp16.safetensors from Comfy-Org/MiniMax-H3
Audio VAE	minimax_h3_audio_vae_fp32.safetensors from Comfy-Org/MiniMax-H3

For accelerated generation, you can optionally pair this model with the minimax_h3_ref2v_turbo_4step_v0.1 LoRA, which enables 4-step fast inference.

VRAM Recommendations

GPU VRAM	Recommended Quant
12 GB	Q4_K_M
16 GB	Q5_K_M
24 GB	Q6_K or Q8_0
