3D AI Studio vs Hunyuan3D

3D AI Studio generates 3D models from text prompts or uploaded images. It also provides AI image generation and editing, texturing, quad remeshing, animation tools, and a built-in render engine. Flow is a node-based canvas for chaining image, text, 3D, video, and batch steps into reusable workflows. Users can choose Prism engines or external engines including Meshy, Tripo, Rodin, and Hunyuan. Exports include FBX, GLB, OBJ, STL, 3MF, USDZ, and BLEND for Unity, Unreal Engine, Blender, or 3D printers. New users receive free credits without a credit card; image-to-3D and text-to-3D cost 20 credits each, while Texture AI, Remesh, and LOD generation are free. The REST API uses pay-as-you-go credits, asynchronous polling, and a default limit of three requests per minute per key. Generated assets are described as private, user-owned, and commercially usable. Browser and API access are available.

Hunyuan3D is Tencent’s system for generating 3D assets from text, images, or sketches. The international platform accepts up to four multi-view images, offers model editing and adjustment, and exports OBJ and GLB files. Its capabilities include text-to-3D, image-to-shape, and texture generation; Smart Topology supports triangular and quadrilateral faces. Tencent Cloud documents API tasks for generation, texturing, topology reduction, component generation, UV mapping, motion, auto-rigging, and format conversion. Hunyuan3D-2.1 releases full model weights and training code, and its repository documents a local Gradio app. A Blender add-on is listed for Hunyuan3D-2. The stated VRAM needs are 10 GB for shape generation, 21 GB for texture generation, and 29 GB for both. First-time API activation grants 100 credits, valid for one year. Paid packs include 1,000 credits for 100 CNY, paid once and 10,000 for 980 CNY, paid once; pay-as-you-go is billed at 0.12 yuan per credit, with monthly settlement.
