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 |
