For clarity, <model> is currently in Safari Technology Preview, behind a feature flag.

I'd like to very much endorse the addition of a page for the <model> element.

Similar to the img, audio, and video elements, the model element provides a way to embed 3D models into a web page.

This code example demonstrates how a .usdz file can be shown on a webpage, with video files as fallbacks. The .usdz file is a format for 3D geometric data.

<model style="width: 400px; height: 300px">
    <source src="assets/example.usdz" type="model/vnd.usdz+zip">
    <picture>
        <source src="animated-version.mp4" type="video/mp4">
        <source src="animated-version.webp" type="image/webp">
        <img src="animated-version.gif"/>
    </picture>
</model>

@Schweinepriester I'd appreciate it if you could take a look at my attempt to create a PR, and fix it. https://github.com/Fyrd/caniuse/pull/6228

I ended up here after seeing <model> added to Safari in macOS Sonoma, but couldn't find anything on caniuse.

It'd be great to keep an eye on this as support rolls out more widely. Maybe @jensimmons can re-open the PR? Thanks!
