It's very impressive. Do they let you export a 3D mesh, though? I was only able to export a video. Do you have to buy tokens or something to export?

I couldn't download it. Model appears to be comparable to Sparc3D, Huyunan, etc but w/o download, who can say? It is much faster though.

you can download it at https://github.com/facebookresearch/sam3. for 3d https://github.com/facebookresearch/sam-3d-objects

I actually found the easiest way was to run it for free to see if it works for my use case of person deidentification https://chat.vlm.run/chat/63953adb-a89a-4c85-ae8f-2d501d30a4...

The models it creates are gaussian splats, so if you are looking for traditional meshes you'd need a tool that can create meshes from splats.

Are you sure about that? They say "full 3D shape geometry, texture, and layout" which doesn't preclude it being a splat but maybe they just use splats for visualization?

On their paper they mentioned using an "latent 3D grid" internally, which can be converted to mesh/gs using a decoder. The spatial layout of the points shown in the demo doesn’t resemble a Gaussian splat either

The linked article of the grandparent says "mesh or splats" a bunch, and as you said their examples wouldn't work if it were splats. I feel they are clearly illustrating it's ability to export meshes.

The model is open weights, so you can run it yourself.
