Recommended hardware
Use only the listed runtime configurations with the exact checkpoint precision. Hardware sizing considers resident pipeline memory, runtime overhead, input and output dimensions, batch size, and safety headroom.
Reference only
Commercial rights are not verified, so this release is not commercially recommendable.
License and self-hosting considerations
The exact pipeline and selected precision must fit on the chosen GPUs. Requirements vary with resolution, duration, batch size, modalities, and runtime; language-model KV-cache rules are not applied.
Hunyuan3D 2.1 is published under other. The release-scoped official license link and verification date are retained with the catalogue record.
