Mozilla Firefox new alt-text generator powered by "fully private on-device AI model" (hacks.mozilla.org)

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

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.

"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..."

Power management is going to be a huge emerging issue with the deployment of transformer model inference to the edge.

I foresee some backpedaling from this idea that "one model can do everything". LLMs have their place, but sometimes a good old LSTM or CNN is a better choice.
