Best AI 3D model generators in 2026, compared

Every generator page shows the same spinning demo, so the useful comparison is not "which is best" but "which is built for the job I have". The jobs differ more than the demos do.

The jobs

A quick mesh from one photo. You have a picture of a thing and want a thing. Speed and a closed, printable mesh matter; the back can be a guess.

A production asset. Clean topology, proper UVs, a full PBR set. The model goes into a game or a product page and will be looked at from every side.

Texturing a mesh you already have. You modelled it; you want the surface painted from a prompt or a reference.

Doing it in bulk, or in your own pipeline. An API, a licence that lets you ship, and a cost per model you can budget.

The engines

Engine	Takes	Gives	Runs where	Licence and cost
Stable Fast 3D (Stability AI)	one image	textured GLB, ~10 s	open weights	community licence: free for individuals and small companies, enterprise licence above a revenue threshold; outputs are yours
TRELLIS.2 (Microsoft)	one image	mesh with PBR materials, high detail, ~30 s at 512, ~1 min at 1024	open weights; free here	MIT, the most permissive of the lot
Hunyuan3D 2.1 (Tencent)	one or several images; a mesh to paint	mesh + PBR via its own paint pipeline, minutes	open weights; the paint half free here	community licence, not granted in the EU, the UK or South Korea
Meshy	text, image, several images; existing meshes for retexture	mesh + PBR up to 8K textures, rigging, animation	hosted	subscription with credits; terms forbid reselling its output through your own service
Tripo	text, image, several images; retexture, rig	mesh + PBR, styles, quad topology option	hosted, with an API	free tier plus credits; API terms allow building products on it
Rodin (Hyper3D)	text, image, several images	mesh + PBR, strong on detail and topology	hosted, with an API	subscription plus API credits

Prices move every quarter; the shapes of the offers do not. Hosted engines charge per model and give you multi-view input, retexturing and rigging. Open-weights engines are free if you run them and are one photo in, one mesh out.

Which one for which job

Quick mesh from a photo: TRELLIS.2 at its lowest resolution. About thirty seconds for a detailed mesh with real PBR maps, and it is what the free generator runs on; Detailed doubles the resolution for a minute of patience. Stable Fast 3D is faster still, ten seconds for a closed mesh with a texture, but the gap in quality is large enough that we stopped offering it.

Production asset: the hosted engines, with several photos. Multi-view input is what turns "the back is a guess" into "the back is the second photo". Tripo and Rodin both offer quad topology and clean UVs; Meshy's textures go highest in resolution. This is also where credits are worth paying: the difference between a $0 mesh and a $0.50 mesh is a day of cleanup.

Texturing your own mesh: Meshy and Tripo if you want it hosted with an API. Of the open models, Hunyuan3D-Paint 2.1 is the one that holds up: it paints the colour, roughness and metallic of an existing mesh from a reference picture, keeping the shape and the UVs. It is what Retexture runs, free, in about a minute. MV-Adapter (MIT) is the alternative with the most permissive licence; we tried it and TRELLIS.2's own texturing, and neither came close on a real model.

Bulk and pipelines: Tripo or Rodin by API, or TRELLIS.2 on your own GPU. Meshy is deliberately left off that list because its terms do not allow reselling its output through a service of your own.

What "open weights" buys you

Three things. You know what the model does, because the code is public. You can run it where you like, which is how a site like this one can give it away. And, licence permitting, nobody can change the terms under you. The trade is that you get the model as published: no multi-view unless the authors trained one, no rigging, no support.

It is worth reading the licence rather than the word "open". TRELLIS.2 is MIT and asks nothing. Stable Fast 3D is free until your company is large. Hunyuan3D is generous about commercial use, but its licence is not granted in the EU, the UK or South Korea, so check where you are before building on it.

How this site picks

One engine per job, the best open one we can run for free, and no dropdown to second-guess. Image to 3D and Text to 3D run TRELLIS.2, with Fast and Detailed as the only choice; Text to 3D paints the photo first with FLUX.2 klein. Retexture runs Hunyuan3D-Paint 2.1. All of them run on shared GPUs on Hugging Face, on a free daily allowance.

When a better open model appears, it replaces the one before. The tools around the generators, Repair, Remesh, Reduce, Convert and Print cost, do not care which engine made the file, or whether one did.
