Hunyuan 3D API for Game-Ready 3D Assets

The Hunyuan 3D API provides programmatic access to Tencent's Hunyuan3D generative models, which turn text prompts and single images into textured 3D meshes. It runs a two-stage pipeline, Hunyuan3D-DiT for shape and Hunyuan3D-Paint for PBR textures, and is served on Atlas Cloud through one OpenAI-compatible endpoint with pay-as-you-go pricing from $0.02 per generation.

Developers use the Hunyuan 3D API to generate game-ready characters, props, and environment pieces, e-commerce and AR product models, and previs meshes for animation and VFX. Because every output ships with clean geometry and optional PBR materials, assets drop straight into Unity, Unreal, Blender, and web or 3D-printing pipelines.

Pro (v3.1) targets maximum fidelity with a configurable 40K to 1.5M face count, 4K PBR textures, four generation modes, and 3 to 6 minute latency across three concurrent jobs. Rapid is a distilled, speed-optimized variant that returns a fixed mid-range mesh with 1K textures in 2 to 3 minutes, which suits high-volume batches and quick iteration.

Generations start at $0.02 each on Atlas Cloud, with transparent pay-as-you-go pricing and no subscription. The same per-call rate applies whether you use the Pro or Rapid tier through Text-to-3D or Image-to-3D, so you only pay for what you generate.

Getting started takes one OpenAI-compatible key from Atlas Cloud, after which you pick a model endpoint, Pro or Rapid in either Text-to-3D or Image-to-3D, and send a prompt or image. There is no GPU to provision, and Day-0 access means you can call new tiers as soon as they land. Start building today.

Image-to-3D takes a single JPG, PNG, or WEBP between 128 and 5000 pixels and up to 6 MB. Text-to-3D accepts prompts of up to 1024 characters in English or Chinese, so you can drive generation from a product photo, concept art, or a written brief.

Meshes are delivered as GLB, OBJ, FBX, STL, and USDZ, covering game engines, DCC tools, AR, and 3D printing. The Rapid tier additionally returns an MP4 turntable preview, letting you review an asset visually before committing it downstream.

Yes. The Hunyuan3D-Paint branch synthesizes a full PBR material set, albedo, normal, metallic, and roughness, using multi-view diffusion for view-consistent surfaces. Pro renders these maps up to 4K, while Rapid delivers 1K textures for lighter workloads.

Hunyuan3D is one of Tencent's most widely adopted 3D foundation models, and the Pro tier here runs the hosted v3.1 engine at 1536³ voxel resolution with a 3.6B-parameter shape backbone. Against lighter open releases it adds higher-resolution geometry, 4K PBR output, and four specialized modes spanning standard, low-poly, sketch-driven, and multi-view generation.
