Quantized diffusion transformers for MiniMax H3, a 33B omni-modal video+audio generator, built from the ComfyUI repack at Comfy-Org/MiniMax-H3. Output is 768p / 24 fps / 4–15 s with synchronized 32 kHz stereo audio. (2K output requires the separate H3-Regenerate-2K module, which is not part of this or Comfy-Org's release.) These are ComfyUI single-file checkpoints, not diffusers models. Filenames follow minimaxh3.safetensors. Both get identical treatment; pick the one matching your workflow. The three INT4 variants exist for fl2va only. All other variants exist for both. This applies to every nvfp4 file, including the convrotint8 ones, which are NVFP4 everywhere except attn.qkvproj. precomputed lookup table. Comfy-Org reports no quality loss, and it's a 34 GB → 20 GB cut. The tradeoff is that it depends on ComfyUI's shape-based detection of the pruned architecture, so the unpruned files are the safer choice outside ComfyUI. ComfyUI build with comfy-kitchen's TensorCoreConvRotW4A4Layout. Note that comfy-kitchen's W4A4…

Compatibility and lineage

Language coverage was not reported.

Reported base models: MiniMaxAI/MiniMax-H3

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.
