Tencent releases Hunyuan3D 2.1: the future of generative 3D is open-source

Tencent has officially released Hunyuan3D 2.1, the first open-source PBR generative 3D model with unprecedented quality.
A historic step forward for AI-powered 3D creativity.

Why is it revolutionary?

Realistic quality: Thanks to an advanced pipeline, the model generates detailed 3D meshes and PBR materials that accurately reflect real-world light behavior.
Objects such as leather, glass, or bronze respond to light just like in the physical world.

Fully open-source, making the following publicly available:

• Training and inference code

• Model weights

• Data pipeline

• Full documentation

• Sample models in GLB format

Optimized for everyone: It also runs on "accessible" hardware.
A consumer-grade GPU, even mid- to low-end, is enough to generate models in just a few seconds.
For the first time, 3D AI technology at this level is truly within reach—for indie developers and professional studios alike.
