Hunyuan 3D 3.1 is Tencent's hosted model, not a file from this site
Tencent's English API page, updated 2026-05-27, lets Model be 3.0 or 3.1. Version 3.1 turns off LowPoly and Sketch and adds four view names. No Hunyuan3D 3.1 weight file was on the GitHub org list or a Hugging Face model card read the same day. The pictures below are the open 2.1 cards, labeled as 2.1.
A still, not a mesh
Nano Banana 2.1 makes a picture, not a Hunyuan file
Nano AI does not call Tencent and does not return a mesh file. Nano Banana 2.1 costs 8 credits for one 1K image, with up to 5 reference images. Eligible new accounts receive 64 credits, enough for 8 of those images. The picture is not a 3D model.

The open 2.1 cards, not a 3.1 mesh
Downloaded on 2026-11-07. Both name Hunyuan3D-2.1. The GitHub counters are GitHub's at that download. They are not a GLB and not a render from this site.


Hunyuan 3D 3.1 is a hosted setting
The searchable name is a version switch on Tencent's 3D API, not a checkpoint this site can run. The English page lists 3.0 and 3.1. It does not publish a weight filename for 3.1. The open line that was found is Hunyuan3D-2.1 on GitHub. Using that repository would be running 2.1, which this page does not do either.
Hunyuan Video 1.5 is a different Tencent model, already on /hunyuan-video-1-5. Meshy's image-to-3D product is on /meshy-image-to-3d. Neither of those pages, and not this one, returns a mesh. If you want a picture of an object before you use someone else's 3D tool, the button opens Nano Banana 2.1.

How Tencent's API page says to call 3.1
Copied from the English SubmitHunyuanTo3DProJob page as read on 2026-11-07. This site has not called it. There is no local install of 3.1 weights because those files were not found.
- 1
Set Model to 3.1 on their API
The action is SubmitHunyuanTo3DProJob and the version is 2023-09-01. The host is hunyuan.intl.tencentcloudapi.com. Model defaults to 3.0. Choosing 3.1 makes LowPoly and Sketch unavailable. Their example body is the word cat. This page does not send that request.
- 2
Send a prompt or an image, not both
A prompt may be up to 1024 utf-8 characters. An image is jpg, png, jpeg, or webp, each side from 128 to 5000, and they recommend staying under 6 MB because encoding grows toward 8 MB. On 3.1 the extra view names are top, bottom, left_front, and right_front, besides left, right, and back. The page does not say those seven names plus the main image in one sentence, so this page does not add the word eight.

Read the limits they print
EnablePBR defaults to false. FaceCount defaults to 500000 and the range is 3000 to 1500000. GenerateType Geometry says only GLB is output and EnablePBR does not apply. A JobId lasts 24 hours. Up to 3 tasks run at once, and the limit is 20 requests per second. None of those files are created here.

Do not treat 2.1 weights as 3.1
The GitHub organization page lists Hunyuan3D-2 and Hunyuan3D-2.1, not a 3.1 repository. The cards on this page are those 2.1 cards. A 2.1 install is a different model. This guide does not invent a 3.1 filename or a folder.
What was found, and what was not
The first cell is a document or a repository, not a weight this site hosts.

How to read the version
3.1 is a parameter
On the API page it is one of two Model values. It is not a file name this site can download.
2.1 is the open card
The samples say Hunyuan3D-2.1 on purpose. They are not a preview of 3.1.
Geometry's GLB is theirs
The API says that mode outputs only GLB. This page does not serve that file and does not offer OBJ either.
A still is the only button
Open Nano Banana 2.1 if you want a picture of an object. It is 8 credits at 1K. It is not a mesh.
3.1, 2.1, and this page
| API 3.1 | Hunyuan3D-2.1 | This page | |
|---|---|---|---|
| Where it runs | Tencent's hosted API | A GitHub repository you would run yourself | Nowhere. The button is a still. |
| Model value | 3.1, and 3.0 is the default | 2.1, a different release | Nano Banana 2.1 |
| LowPoly and Sketch | Unavailable on 3.1 | Not described on the 3.1 API page as a 2.1 feature | Not offered |
| File out | Geometry mode: only GLB, on their API | Whatever that repository documents for 2.1, not repeated as 3.1 | No GLB and no OBJ |
| Views | left, right, back, plus top, bottom, left_front, right_front on 3.1 | Not the same list | No multi-view upload |
| Price here | Tencent's own billing, not copied as a dollar figure | Not priced on this site | 8 credits, 1K |

How to leave with a still
- 1
Read the version you actually need
3.1 is the hosted parameter. 2.1 is the open repository. They are not the same install.
- 2
Open Nano Banana 2.1 for a picture
One image is 8 credits at 1K. It is a picture of an object, not a model file.
- 3
Use Tencent's own console for 3.1
This site will not sign you into Tencent and will not hand you a GLB or an OBJ.
Stills, if you use the button
Object stills for Nano Banana 2.1. They are not 3D prompts and they do not name a mesh format.
Cup
A matte ceramic cup on linen, morning window light. no people, no faces, no logos, no readable text.
Courtyard
An empty stone courtyard after rain, one clay pot by a wall. no people, no faces, no logos, no readable text.
Shelf
A folded grey cloth and a brass key on a dark shelf. no people, no faces, no logos, no readable text.
Window
One unbranded plant on a windowsill, soft morning light, empty room. no people, no faces, no logos, no readable text.
Easy mistakes
- LowPoly or Sketch on 3.1
- The API page says those parameters are unavailable when Model is 3.1.
- Prompt and image together
- The page says they cannot coexist, except the Sketch mode that 3.1 turns off.
- A download button on this site
- There is not one. Geometry’s GLB line is Tencent’s output rule, not a file this page serves.
A still, not a mesh
Nano Banana 2.1 makes a picture, not a Hunyuan file
Nano AI does not call Tencent and does not return a mesh file. Nano Banana 2.1 costs 8 credits for one 1K image, with up to 5 reference images. Eligible new accounts receive 64 credits, enough for 8 of those images. The picture is not a 3D model.
FAQ
Hunyuan 3D 3.1 questions
What the API page said, and what this page will not hand you.
Can I download a 3.1 GLB here?
No. The API says Geometry mode outputs only GLB on Tencent's side. This page does not call that API and does not offer GLB or OBJ.
Are the sample cards 3.1?
No. They are the Hugging Face and GitHub cards for Hunyuan3D-2.1. The counters on the GitHub card are from the download on 2026-11-07.
Why not say eight views?
The API lists left, right, back, and, only on 3.1, top, bottom, left_front, and right_front. It does not print the word eight in that paragraph. This page keeps the names and does not add the count.
Is Hunyuan Video 1.5 the same model?
No. That page is a video model. This page is the 3D API. They link to each other so the names are not mixed.
Does 64 credits buy a Tencent job?
No. 64 credits are 8 images of Nano Banana 2.1 at 8 credits. They are not Tencent's concurrency, FaceCount, or JobId.
Is Nano AI Tencent?
No. Nano AI is not affiliated with Tencent or Hunyuan. The button runs Nano Banana 2.1.
