Open Source Image to 3D: The Models Behind TripoSplat

"Open source image to 3D model" gets used loosely. Sometimes it means a public research repository and its checkpoints; sometimes it means a hosted product that merely uses a public model. This page separates the two so you can tell what you can download, study, and self-host, and what is a managed service.

What is open, and what is hosted

The image-to-3D model this site is built around, TripoSplat, is published by the VAST-AI research group as public source code with a research implementation and a public demo Space. That is the genuinely open part: the code, the method, and the demo are theirs, and their licence is theirs to set. The official resources link straight to the upstream repository and the demo.

The website you are reading is a separate, independent hosted service. It runs the model through a generation provider so you do not have to set up a GPU, and it wraps the model with the workspace, credits, task history, and the browser tools. That wrapper is not the upstream project, and this site is not the official website for the upstream model vendor.

What you can actually do with the open parts

• Read the source. The research implementation, training approach, and inference code are public in the upstream repository.
• Run the public demo. The upstream project hosts a demo Space you can open directly from the official resources.
• Self-host, if you have the hardware. Running the model yourself is possible where the licence and your compute allow it, but it is a GPU-and-setup project, not a browser click.
• Use the hosted lane if you do not want the setup. The AI 3D Generator runs the same kind of job without a local GPU; a signed-in run is priced 48-72 credits.

What open source does not give you

• A production SLA. Research code and demos are not managed services with uptime promises.
• Free hosting. Running the model yourself still costs GPU time.
• A licence-free pass. The upstream licence is the upstream licence; check it before commercial use.
• This site's tooling. The converters, viewers, and inspectors in free tools are this service's own browser utilities, not part of the upstream project.

Common mistakes

• Assuming this site is the upstream project. It is an independent hosted service that uses the model; the repository and demo belong to the research group.
• Assuming the demo will not queue. Public Spaces are shared; expect waits.
• Treating the model licence as unrestricted. Read it before shipping anything commercial.
• Expecting a mesh from an open splat model. The upstream model is about Gaussian splats; mesh output is a different lane.

FAQ

Is the image-to-3D model behind TripoSplat open source?

Yes - the upstream TripoSplat model is published as public research code with a demo, and the official resources link to it. The hosted website around it is separate.

Can I download the model and run it myself?

Where the licence and your hardware allow it, yes. It is a GPU setup rather than a browser workflow.

Is this site the official website of the model?

No. This site is an independent hosted service built on the model and states the upstream project as the source.

Where can I find the upstream project?

The links to the source repository and the demo Space are collected with the other official resources on the AI 3D Generator page.

To run a hosted job without the setup, open the AI 3D Generator; to understand the output first, read 3D Gaussian splatting.
