Rodin vs Hunyuan3D vs TripoSR: Which AI 3D Generator Is Worth It in 2026?

Rodin vs Hunyuan3D on licensing is a choice between a paid plan and a regional license: Rodin reserves commercial licensing for its paid plans, while Hunyuan3D's open 2.1 weights come with a community license that does not apply in the EU, the UK, or South Korea. Rodin's feature page says paid plans add commercial licensing, and its pricing page describes paid plans as including broader export and usage rights.

The Tencent Hunyuan Community License for 2.1 states that it does not apply in the European Union, the United Kingdom, or South Korea, and requires companies whose products had more than 1 million monthly active users when 2.1 was released to request a separate license from Tencent. For a studio in Berlin or London, that is a real stop sign before a single model is generated, and the hosted 3.0 engine runs under Tencent's own platform terms instead.

TripoSR is the simplest answer here. Every hosted plan on triposr.org includes a commercial license and watermark-free downloads, so the model you generate is ready to sell, put in a game, or deliver to a client the moment you download it. And the open-source TripoSR model is plain MIT: no territory clause, no user cap, and no attribution requirement on what you make with it.

All three generators produce PBR-textured 3D models; Rodin pushes geometric detail and export breadth furthest, Hunyuan3D separates shape and texture into two dedicated models, and the hosted TripoSR version delivers a PBR-textured GLB with selectable texture tiers. Rodin Gen-2.5 targets up to 10 million polygons with watertight, manifold geometry and albedo, roughness, and metalness maps, and exports GLB, FBX, OBJ, STL, USDZ, glTF, 3MF, and DXF.

Hunyuan3D builds each model in two stages, a shape model followed by a PBR paint model, and the 2.1 README calls the texture pipeline physics-grounded. The hosted engine exports mainstream formats such as OBJ and GLB, which covers most game engines and DCC tools.

The hosted version on triposr.org outputs a full PBR-textured GLB, the format that opens directly in Blender, Unity, Unreal, three.js, and AR viewers, and lets you choose a Standard, Ultra, or Max texture tier for each generation. Background removal runs automatically, so a product photo goes in as is and a clean, textured model comes out.

Hunyuan3D's hosted engine accepts the widest range of inputs of the three: text, a single image, up to four multi-view images, or a sketch, according to Tencent's global launch announcement. That makes it the most flexible starting point when you have a concept drawing or several photos of the same object.

Rodin covers image-to-3D and text-to-3D on its free plan, includes limited multi-image input there, and opens up full multi-image input on its paid Creator plan. The open Hunyuan3D 2.1 weights, by contrast, take an image as input, so the extra input types belong to the hosted engine.

The hosted version on triposr.org covers the two inputs most people actually start from: one photo or a text prompt. Both run on every plan, so you can go from an idea to a textured model without first making a reference image, and the open-source TripoSR model is a single-image reconstructor, which is exactly what makes it so fast.

Rodin AI costs 30 USD a month for its cheapest paid plan, Creator (24 USD a month billed yearly, about 60 models by Rodin's estimate), while Hunyuan3D gives web users 20 free generations a day and enterprise API users 200 free credits. Rodin's Business plan costs 120 USD a month (96 USD billed yearly), and credits can also be bought directly at 1.5 USD each; its pay-by-result model lets you generate before you confirm, so you only spend a credit on a result you keep.

Hunyuan3D's paid path runs through Tencent Cloud. The billing documentation lists 200 free credits per user valid for one year, postpaid billing at 0.02 USD per credit that you switch on yourself, and prepaid packs from 1,000 credits for 15 USD up to 100,000 credits for 1,350 USD. A Pro generation costs 25 credits, about 0.50 USD, and failed tasks are not charged.

The hosted version on triposr.org keeps it simple. You can buy a one-time credit pack with no subscription, which covers image-to-3D and text-to-3D with full PBR texture output, or pick a monthly or yearly plan if you generate often. Every plan, from Basic to Premium, includes the same full PBR textures, watermark-free downloads, and commercial license; bigger plans add credits, longer storage, and faster generation. And if your budget is zero, the open-source TripoSR model is free to download and run as many times as you like.

The Hyper3D Rodin API is included with Rodin's Business plan (120 USD a month, or 96 USD billed yearly), while the Hunyuan3D API runs on Tencent Cloud with 200 free credits and pay-as-you-go billing at 0.02 USD per credit. Rodin's pricing page lists full API access only on Business and custom API access on Enterprise; the Free and Creator plans do not include it.

Rodin's API charges per credit: the Gen-2.5 specification says a base generation costs 0.5 credits, with 0.5 more for the Extreme-High model and 2.0 more for extreme-high textures. Business includes 208 credits a month, which Rodin estimates at about 416 models. Requests authenticate with a bearer token, which you create in the Hyper3D API dashboard.

Hunyuan3D's API, now branded Tencent HY 3D Global, is asynchronous: you submit a job, receive a JobId, and poll until the status is DONE. Getting credentials takes a Tencent Cloud account with real-name verification, activating the service in the console, and creating a SecretId and SecretKey pair. If you would rather skip API keys entirely, the open-source TripoSR model is MIT-licensed, so you can serve it behind your own endpoint with no per-call fee and no vendor account.

Running Hunyuan3D 2.1 locally takes about 10 GB of VRAM for shape generation, 21 GB for texturing, and 29 GB for the full shape plus texture pipeline, according to its README, which also offers a low-VRAM mode. The README lists macOS, Windows, and Linux support and was tested with Python 3.10 and PyTorch 2.5.1 with CUDA 12.4; the model card lives on Hugging Face at tencent/Hunyuan3D-2.1.

For ComfyUI users, one community route is the node ComfyUI-Hunyuan3d-2-1 by visualbruno, listed first in the official README's community contribution leaderboard. ComfyUI's own documentation describes native support for the earlier Hunyuan3D-2mv model, without texture and material generation, so the textured 2.1 pipeline in ComfyUI runs through the community node. Rodin, for its part, is a closed hosted service with no weights to download.

The open-source TripoSR model is the lightest of the three by a wide margin. It reconstructs a mesh from one image in under half a second on an NVIDIA A100, needs about 6 GB of VRAM, falls back to CPU, and is MIT-licensed, so it runs on a mid-range gaming laptop, inside a pipeline, or at batch scale on cloud GPUs with no license strings. If you want the polished, textured result without any setup, the hosted version on triposr.org runs it for you in the browser.
