| # FastVideo FastH3 V2 NVFP4 |
|
|
| Repackaged model files for ComfyUI. |
|
|
| Original model repository: https://huggingface.co/FastVideo/FastVideo-FastH3-8-Step-V2 |
|
|
| FastH3 V2 with its transformer quantized to NVFP4, for NVIDIA Blackwell GPUs: RTX 50 series, RTX PRO 6000 and |
| DGX Spark. It is built from `fastvideo_fasth3_8step_v2_pruned_bf16.safetensors` in |
| [FastVideo/FastVideo-FastH3-Comfy](https://huggingface.co/FastVideo/FastVideo-FastH3-Comfy), which also has the |
| BF16 and INT8 builds for other GPUs. |
|
|
| Use the **FastVideo FastH3: Text to Video** template (ComfyUI 0.36.0 or later) and select |
| `fastvideo_fasth3_8step_v2_pruned_nvfp4.safetensors` (13.6 GB) in its `UNETLoader`. Keep the template's sampler |
| settings: 8 steps, `res_multistep`, `simple`, and the `MiniMaxH3SigmaShift` node at 10 (video) and 3 (audio). |
|
|
| Place the files in the following folders: |
