TripoSR: open-source image to 3D
TripoSR is a fast, small image-to-3D model from Stability AI and Tripo AI, released in March 2024. It reconstructs a mesh from one image in under a second on a data-centre GPU and needs about 6 GB of memory, so it runs on ordinary gaming cards. It is MIT licensed. Its quality is behind 2025 models, but it is still the easiest one to run.

What TripoSR is
TripoSR is a feed-forward reconstruction model: one pass through a transformer turns an image into a 3D representation, and a mesh is extracted from it. There is no slow optimisation loop, which is why it is fast. Stability AI and Tripo AI released it together in March 2024, building on the LRM (Large Reconstruction Model) design.
The output is a mesh with colour stored per vertex, not a texture map. That keeps it simple, but fine detail and print on the object come out soft.
Running TripoSR
The README says the default settings use about 6 GB of GPU memory for one image, so an RTX 3060 or better works. On an A100 it reconstructs in well under a second. Clone the GitHub repo, install the requirements, and run the script on an image; it writes an OBJ or GLB. Background removal is built in.
The official Hugging Face Space for TripoSR was not running when we last checked. Running it locally or in a notebook is the reliable route.
TripoSR next to newer models
TripoSR set the speed bar in early 2024. Models from 2025, such as Hunyuan3D 2.1, TRELLIS.2 and Tripo AI's own TripoSG, produce much cleaner geometry and real texture maps, at the cost of a bigger GPU and more time. Choose TripoSR when you need speed, a small GPU or an MIT licence on a laptop-class card; choose a newer model when the result has to look like the product.
No GPU, no setup?
2dto3D runs a production pipeline for product photos: it generates the hidden views first, then builds a textured model at real size, with AR, an embed snippet and export to 7 formats. About 5 minutes per model, from $2, nothing to install.
Your first model is $2, refunded in full within 14 days if you do not like it. Try it with a sample photo
Frequently asked
Is TripoSR free for commercial use?
Yes. TripoSR is released under the MIT licence, which allows commercial use of the code, the weights and the outputs.
How fast is TripoSR?
Under a second per image on an NVIDIA A100, according to its authors. On a consumer GPU, expect a few seconds. That makes it one of the fastest open image-to-3D models.
Is TripoSR the same as Tripo3D?
No. TripoSR is an open research model from 2024. Tripo3D is Tripo AI's commercial service, which runs its newer, closed models and is much stronger.
