GGUF quantizations of FastVideo FastH3 8-Step V2 for use with ComfyUI / ComfyUI-GGUF. These GGUFs were converted from the full official BF16 FastH3 V2 transformer weights released by FastVideo. Original model: https://huggingface.co/FastVideo/FastVideo-FastH3-8-Step-V2 FastH3 8-Step V2 is a distilled MiniMax-H3 checkpoint from FastVideo designed to generate synchronized video and audio using only 8 transformer forwards. The official V2 release uses: Additional quantizations may be added later. The official FastH3 V2 transformer is distributed as a large sharded BF16 checkpoint. For these releases, the complete transformer was reconstructed and converted to the tensor layout expected by ComfyUI before GGUF quantization. The conversion preserves the FastH3 architecture, including: High-precision projection/conditioning tensors are preserved as F16/F32 where appropriate rather than indiscriminately quantizing every tensor. ComfyUI-GGUF is required. Place the downloaded GGUF in: Restart ComfyUI or refresh your model list after installing the model. Load the model using your GGUF unet loader. FastH3 V2 is…

Compatibility and lineage

Language coverage was not reported.

Reported base models: FastVideo/FastVideo-FastH3-8-Step-V2

Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.

Use and evaluate

Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.

No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
