Hunyuan3D

Hunyuan3D suits creators and developers who need to generate and refine 3D assets from text or visual references. Its open models and broad API workflow are compelling; self-hosting demands a capable GPU, while hosted API work may require expiring credit packs.

Overview

Hunyuan3D spans a web service, APIs and open models. The international platform accepts text, images or sketches, including up to four multi-view images, and supports model editing and OBJ and GLB export. That range makes it more useful than a one-shot generator for creators who need to adjust assets or feed them into a production workflow.

The open-source release includes full model weights and training code, giving community developers a basis for fine-tuning and downstream applications. The trade-off is practical: local generation requires substantial VRAM, while API usage is metered through credits or pay-as-you-go billing.

Key features

Generation and texturing

Hunyuan3D-2.1 includes an image-to-shape model and texture generation with a physically based rendering texture synthesis pipeline. The Hunyuan3D-2 repository also identifies text-to-3D as a supported capability. On the international platform, users can start from text, images or sketches, with up to four views for reference. This input flexibility suits both concept-led work and asset creation from existing imagery.

Editing and production tools

The platform offers model editing and adjustment, while Smart Topology optimizes mesh topology for triangular or quadrilateral faces. Tencent Cloud API tasks extend beyond generation to texture creation, topology reduction, component generation, UV mapping, motion generation, auto-rigging and format conversion. These capabilities make Hunyuan3D a stronger fit for workflows that need several asset-processing steps, though the API’s default professional-edition limit is three concurrent tasks shared across main and sub-accounts.

Developer access

The repository documents a local Gradio app, API documentation and an API server, and the Hunyuan3D-2 repository includes a Blender add-on. Tencent points users to WeChat and Discord groups for project discussion and help. This is a practical toolkit for developers and technical artists, rather than a low-setup option for anyone without suitable hardware or API capacity.

Pricing

Hunyuan3D is open source, and the API has a one-time free allowance as well as paid usage options. First-time service activation grants 100 credits, valid for one year. That is useful for an initial evaluation, but it is a finite resource pack rather than an ongoing free quota.

• New-user credit pack: free for 100 credits, automatically issued after activation; the one-time pack expires after one year.
• 1,000-credit pack: 100 CNY, paid once; credits are valid for one year from purchase.
• 10,000-credit pack: 980 CNY, paid once; credits are valid for one year from purchase.
• 50,000-credit pack: 4,750 CNY, paid once; credits are valid for one year from purchase.
• 100,000-credit pack: 9,000 CNY, paid once; credits are valid for one year from purchase.
• Pay-as-you-go: custom pricing; billed at 0.12 yuan per credit, with monthly automatic settlement after activation.

The larger packs reduce the stated price per credit, but commit more spend upfront and still expire after a year. Pay-as-you-go avoids a bulk purchase, though monthly settlement makes usage costs an ongoing consideration. The open models avoid API credit charges, but local hardware requirements are the relevant cost in that route.

Platforms

Hunyuan3D supports API, Linux, macOS, self-hosted, web and Windows. The Hunyuan3D-2.1 repository gives minimum VRAM requirements of 10 GB for shape generation, 21 GB for texture generation and 29 GB for combined shape and texture generation. Separate requirements matter: a machine that can generate shapes may still fall short for texturing or the full combined workflow.

Who it's for

Hunyuan3D is best suited to developers, technical artists and teams that want an open model to adapt or an API that covers asset generation and downstream processing. It is also a reasonable choice for creators with suitable GPUs who want local deployment. It is a weaker fit for users seeking a lightweight local setup or a predictable, unlimited hosted allowance.

Pros and cons

• Pro: Text, image and sketch inputs—including multi-view references—give creators several ways to start an asset.
• Pro: Full weights and training code support fine-tuning and downstream development, rather than locking users to a hosted workflow.
• Pro: Editing, topology tools, multiple export formats and API production tasks support work beyond initial generation.
• Con: Combined local shape and texture generation calls for 29 GB VRAM, a substantial requirement that rules out many ordinary setups.
• Con: Free API access is a one-time 100-credit pack, and paid packs expire after a year.
• Con: Professional API concurrency defaults to three shared tasks, which can constrain teams running parallel jobs.

Alternatives

AI 3D Model Generators is a useful starting point for comparing tools across the category. Choose Meshy instead if a freemium service with a stated monthly free allowance—100 credits and 10 free downloads for Meshy 6 Lite models—better suits a hosted workflow. Hi3D may suit users who prefer a lifetime free allowance, with 100 credits for up to 10 generations and one concurrent task. For a free-to-try option that requires an invitation code to register, consider Unique3D. Polar Cloud is the alternative to consider when managing 3D printing is the priority: its free plan includes one printer and five print jobs per month, with mesh-only files and a 30 MB file limit. Stable Fast 3D offers a free community license for research and commercial use up to $1,000,000 in annual revenue. Polycam is another option, with a free plan for limited captures and GLTF exports. Crisp3D has a free plan with one concurrent task, public models and no downloads. Hyper3D Rodin is another alternative to consider.

Verdict

Choose Hunyuan3D if you want open, adaptable 3D generation with texturing, editing and API tools in the same ecosystem. Its breadth and released training materials are the main reasons to choose it; the main reasons to look elsewhere are the high VRAM bar for full local generation and the finite, expiring credits and concurrency cap on API use. Also account for Tencent’s announced service transition: Hunyuan 3D 2.5 and 3D-person generation 1.0 APIs stopped accepting new purchases on September 22, 2026, with termination scheduled for October 20, 2026.
