# How to run SAM 3D without a GPU

**How can I run SAM 3D without a GPU or a local install?**

SAM 3D has open weights, so you can run it yourself, but you need the hardware: a Linux machine with a 32GB NVIDIA GPU for SAM 3D Objects. Without a GPU, the simplest route is a hosted version. In OTOY Studio, SAM 3D runs in the browser from 2 credits (€0.02) per run, with nothing to install, on the same canvas as 100+ other image, video and 3D models.

Meta's SAM 3D models. SAM 3D Objects reconstructs the shape, texture and layout of an object from one image. SAM 3D Body recovers a full 3D human body mesh from one image.

## Running it yourself

**Run it yourself if:** You have a 32GB Linux GPU and need to process large image sets, or want to build on the code.

## Running it without a GPU in OTOY Studio

| Node | Takes | Credits per run |
|---|---|---|
| SAM 3 Objects | Prompt plus image | 2 (from €0.02) |
| SAM 3 Body | Prompt plus image | 2 (from €0.02) |

1. Sign up free at https://app.otoy.studio. The free plan includes 100 credits a month, no credit card.
2. Add a SAM 3D node to a canvas and connect your inputs.
3. Run it. It runs on OTOY Studio's hosted GPUs, so your machine only needs a browser.
4. Chain the output into other models in the same workflow, or download it.

1 credit = €0.01. Prices are list prices before plan discounts (paid plans take 10% to 25% off every run). Model page: [SAM 3D](https://otoy.studio/models/sam-3-3d).
