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..."

From your OP description:

EDIT: the AI creates an initial description, which then receives crowdsourced additional context per-image to improve generated output. look for the “Example Output” heading in the article.

That's wrong. There is nothing crowd sourced. What you read in the article is that when you add an image in the PDF editor it can generate an alt text for the image, and you as a user validate and confirm it. That's still local PDF editing though.

The caching part is about the model dataset, which is static.
