1/ today we're releasing muse spark, the first model from MSL. nine months ago we rebuilt our ai stack from scratch. new infrastructure, new architecture, new data pipelines. muse spark is the result of that work, and now it powers meta ai. 🧵

[Justin Ryan ᯅ @justinryanio]

I tried Meta’s new SAM 3D tool. It’s impressive.

In about ten seconds it segmented the bed from my photo and turned it into a full 3D object. The quality surprised me.

Only catch right now is it exports as PLY. I’d love USDZ so I can drop it straight into my room on Vision Pro.

[Jiafei Duan@CVPR2026 @DJiafei]

My prediction: we’re about to see hundreds of robotics papers built on SAM3D. Waiting for the first one to drop 👀

SAM3 & SAM3D from @metaai are just too good to be true!

SAM 3D enables accurate 3D reconstruction from a single image, supporting real-world applications in editing, robotics, and interactive scene generation.

Matt, a SAM 3D researcher, explains how the two-model design makes this possible for both people and complex environments.

3Dfy anything from a single image!

Very thrilled to announce SAM 3D. From an input image, select any object you want, 3Dfy it!

@georgiagkioxari @holynski_ this looks amazing!

[Alexandr Wang @alexandr_wang]

We also dropped SAM 3D, two state-of-the art models that enable 3D reconstruction of objects and humans from a single image

[Fu-Jen Chu @FuJenChu1]

Thrilled to announce SAM 3D today! — our new foundation model that turns any single image into a decomposable 3D scene of objects and humans.

So proud of what our team has built over the past months — and excited for everyone to try it out!

Introducing SAM 3D, the newest addition to the SAM collection, bringing common sense 3D understanding of everyday images. SAM 3D includes two models:

🛋️ SAM 3D Objects for object and scene reconstruction

🧑‍🤝‍🧑 SAM 3D Body for human pose and shape estimation

Both models achieve state-of-the-art performance transforming static 2D images into vivid, accurate reconstructions.
