Experimenting with local alt text generation in Firefox Nightly – Mozilla Hacks - the Web developer blog
hacks.mozilla.org
Firefox 130 will feature an on-device AI model that automatically generates alt-text for images, integrated into its built-in PDF editor.

New accessibility feature coming to Firefox, an “AI powered” alt-text generator.

"Starting in Firefox 130, we will automatically generate an alt text and let the user validate it. So every time an image is added, we get an array of pixels we pass to the ML engine and a few seconds after, we get a string corresponding to a description of this image (see the code).

…

Our alt text generator is far from perfect, but we want to take an iterative approach and improve it in the open.

…

We are currently working on improving the image-to-text datasets and model with what we’ve described in this blog post…"

    Interesting. It also made me look at the MDN docs again. img alt is consistent to that. I wasn’t aware of the empty for omittable images.

    I also looked at figure again, and in my interpretation it does declare that figcaption is to be used.

    figure represents self-contained content. figcaption provides the accessible name for the parent. The accessible name is is the text associated with an HTML element that provides users of assistive technology with a label for the element.

    The resolution order being aria-labelledby, aria-label, input[type=button][value], input[type=image]|img|area[alt], …

    So figcaption takes priority over img alt.
