🛠️ Engineering & Pruning Details

• Curve-Pruned AdaLN Architecture: The 51 unpruned AdaLN modulation modules ([Out, 2688]) from the original 34GB checkpoint were projected onto the canonical rank-8 Ref2VA subspace (adaln_basis + adaln_mean), reducing parameters by 13.03 Billion and saving ~26 GB of disk space.
• Lossless Precision Guards: All normalization layers (RMSNorm, LayerNorm), timestep embeddings (adaln_t_table), and modality input/output heads (video_patch_proj, audio_patch_proj, final_layer.video_out, final_layer.audio_out) are preserved in lossless FP32.
• ConvRot Un-Rotation: Source INT8 weights were accurately un-rotated using ComfyUI's exact Regular Hadamard ($H_4^{\otimes 4}$) transform in float64 before K-quantization, eliminating quantization artifacts and color shifts.
• LoRA Compatibility: Includes the canonical adaln_affine.safetensors curve basis, ensuring 100% compatibility with the ComfyUI pruned H3 LoRA and PowerLoRA stack ecosystem.

🚀 How to Use in ComfyUI

1. Place your chosen .gguf file into your ComfyUI models folder: ComfyUI/models/diffusion_models/
2. Load the model using UnetLoaderGGUF.
3. Pair it with the Qwen3-VL text encoder and MiniMax-H3 Video + Audio VAEs.
