What is Hunyuan3D?

An AI from Tencent that generates high-fidelity 3D models (geometry + PBR textures) from images or text, combining the shape-generation model Hunyuan3D-DiT and the texture-synthesis model Hunyuan3D-Paint. The current flagship is the commercial 3.1 (up to 8-view input), while the latest open-source version 2.1 also supports local execution and commercial use. The official web app has a free tier of 20 generations per day.

About "Hunyuan3D"

What is Hunyuan3D

Hunyuan3D is an AI developed by Tencent that generates high-fidelity 3D models from images or text. From a single image, a sentence, or a sketch, it automatically generates 3D assets with geometry (mesh) and PBR textures (materials). Aimed at production for games, e-commerce, video, 3D printing, and more, its major distinction is that a state-of-the-art commercial model and an open-source version coexist. The OSS version has surpassed 3 million cumulative downloads on Hugging Face and is highly rated on GitHub.

The current flagship is Hunyuan3D 3.1 (global version, closed, up to 8-view input), available on the official web app and the Tencent Cloud API. Meanwhile, the latest open-source version is Hunyuan3D 2.1 (model weights published, commercial use allowed), which supports local execution and your own fine-tuning. *In August 2026, the Hunyuan brand was renamed "Hy."

Building geometry and texture in two stages

Rather than generating 3D all at once, Hunyuan3D generates "geometry" and "texture" separately. First, the shape-generation model Hunyuan3D-DiT creates a mesh from the image; then the texture-synthesis model Hunyuan3D-Paint applies physically based (PBR) materials such as Albedo, Metallic, and Roughness. This division balances geometric accuracy with realistic appearance.

DCC integration — use in Unity / Unreal / Blender

How to use

Choose the official web app or open source

Use the official web app to try it easily, or the open-source version (2.1) on GitHub / Hugging Face to run it locally.
Enter an image or text

Input the image you want to turn into 3D, or a description of what you want to make.
Generate the geometry

Hunyuan3D-DiT generates the mesh.
Apply the texture

Hunyuan3D-Paint synthesizes the PBR texture.
Export and use

Export as OBJ / GLB and import into Unity, Unreal, Blender, and more.

How it differs from other 3D generation AIs

3D generation AIs split largely into "open source vs. commercial SaaS." Hunyuan3D stands out by offering both a top-tier open-source version (2.1) and the latest commercial version (3.1), with a broad ecosystem that includes part decomposition and rigging.

Aspect	Hunyuan3D	Meshy	Tripo
Availability	OSS (2.1) + commercial (3.1)	Commercial SaaS	Commercial SaaS
Self-hosting	Local execution and fine-tuning	Mainly cloud	Mainly cloud
Extensions	Part decomposition, rigging, DCC integration	3D generation, animation	3D generation

For easy cloud-based 3D generation, Meshy and Tripo AI; for research on editable, part-decomposed 3D, Omnipart are comparison points. When you want to embed it into your own environment as open source, or leverage a large-vendor ecosystem, Hunyuan3D is a strong option.
