| The upstream transformer file states that it is based on Tencent HunyuanDiT. |
| The upstream NOTICE reads: |

| This family implements the TripoSG transformer architecture with Diffusers |

| derivation carries Tencent Hunyuan Community License obligations for this code |
| has not been determined. |
