Hunyuan3D 2.1
A solid pick for self-hosting and full data control.
Overview
Hunyuan3D 2.1 turns images or text prompts into 3D meshes and textures, and does so with just 3 billion parameters — light enough to run on a laptop-class GPU. Weights are open and Tencent's community licence permits commercial use below 100 million monthly active users. The real caveat lies in the fine print: some versions of that licence carry territorial restrictions that may touch the EU, so it's worth reading the clause carefully before any European deployment, on-premise included.
Skill profile

Three independent measures
What people prefer, what the model can do, what the market uses. Each source has its biases and none is enough on its own: we show them side by side, never blended.
Strengths
- Open-source and self-hostable
Limitations
- API pricing not disclosed
Who is it for
- you want to control cost or self-host
- your data must stay in the EU
Ideal use cases
- 3D asset prototyping
- Game model generation
- Rapid product design
- E-commerce 3D content

Quality of this card’s data
This score measures the quality of the data on this card: price, context, Elo, licence, documented, sourced and fresh. It measures neither the model nor its compliance: for that, see the Trust Index above.
