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.

"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..."

I don't think they're likely to do a better job than humans any time soon. We can hope that it won't be extremely misleading too often.

I dunno, I suspect most human alt texts to be vague and non descriptive. I'm sure a human trying their hardest could out write an AI alt text.. But I'd be pretty shocked if AI's weren't already better than the average alt text.

Alt text: It's for SEO, isn't it?

Sure, assuming the human is actually putting effort into the task. But we know that able-bodied society is generally, at best, dismissive of the needs of the disabled and, at worst, discriminatory. I very much doubt that the majority of fully sighted humans working in this area are taking the time required to view the problem from the point of view of the visually-impaired minority and then putting in the effort required to deliver the best possible solution for them. Not every website is run by some massive company with employees specifically dedicated to this task. For many it will be an afterthought, and that's where AI descriptions will shit all over the lazy human ones. Additionally, alt text contributes to SEO which means many will be tailoring it to their search ranking instead of the needs of the user.
