Meta releases AI 'SAM 3D Body' and 'SAM 3D Objects' that can cut out only the desired person or object from a single photo and create a 3D model
Meta announced SAM 3D , an AI capable of generating 3D models from images, on Thursday, November 19, 2025. SAM 3D is divided into two parts: SAM 3D Body , which specializes in human bodies, and SAM 3D Objects , which specializes in objects. Both can generate higher-quality 3D models than competing products.

SAM 3D Body is an AI that can recognize the body shape and pose of a human in an image and create a 3D model.
The results are below: SAM 3D Body and several competing AIs were used to generate 3D models, and humans were asked to determine which was higher quality. Blue indicates the percentage of cases where SAM 3D Body was judged to be of higher quality, white indicates a tie, and gray indicates the percentage of cases where the competing AI was judged to be of higher quality. SAM 3D Body won against all the AIs it compared.
You can actually use SAM 3D Body on the demo site below.
Create 3D bodies | Meta AI Demos
When you access the demo site, you will be presented with an image selection screen where you can choose from pre-prepared images or upload your own.
Upload an image and it will automatically recognize people in the image.
Once the recognition process is complete, click on the person you want to create a 3D model of.
Within seconds, a 3D model of the body shape and pose was generated.
The 3D model can be moved around freely, and you can create a reference image from a single photo in all directions, which can be used as a reference for drawing, etc.
SAM 3D Objects is an AI that can accurately extract only specific objects from an image containing multiple objects and create a 3D model.
The results of a human evaluation of the performance of SAM 3D Objects and competing AI are shown below. SAM 3D Objects recorded a win rate of over 80% against all competing AIs.
SAM 3D Objects is also available on the demo site.

When you access the demo site, an image selection screen will appear.
When you upload an image, the following screen appears:
Click on the object in the image you want to create a 3D model of. When I clicked on the torso of the doll, only the area around the torso was painted red.
Click on other parts of the object so that the entire object is filled. In this case, I clicked on the doll's head, and the entire doll was filled. In this state, you can generate a 3D model by clicking 'Generate 3D' in the bottom right.
The generation process takes just a few seconds.
The back side looks like this. The parts not visible in the image are filled in seamlessly.
SAM 3D Body and SAM 3D Objects checkpoints are available for free. For more information on how to download them, please see the links below.
