No pun intended but it's indeed an unfortunate choice of words on my part.

It might be that you’re not perfectly clear on what exactly you’re trying to convey with the image and why it’s there.

What would you put for this? "Graph of All-Transactions House Price Index for the United States 1975-2025"? https://fred.stlouisfed.org/series/USSTHPI

Charts are one I've wondered about, do I need to try to describe the trend of the data, or provide several conclusions that a person seeing the chart might draw?

Just saying "It's a chart" doesn't feel like it'd be useful to someone who can't see the chart. But if the other text on the page talks about the chart, then maybe identifying it as the chart is enough?

I really like how you framed this as the takeaway or learning that needs to happen as what should be in the alt and not a recitation of the image. Where I've often had issues is more for things like business charts and illustrations and less cute cat photos.

The logic stays the same though the answer is longer and not always easy. Just saying "business chart" is totally useless. You can make a choice on what to focus and say "a chart of the stock for the last five years with constant improvement and a clear increase by 17 percent in 2022" (if it is a simple point that you are trying to make) or you can provide an html table with the datapoints if there is data that the u…

but the table exists outside the alt text, right? i don't know a mechanism to say "this html table represents the contents of this image" , in a way that screen readers and other accessibility technologies take advantage of

The figure tag has both image and caption tags that link them. As far as I remember, some content could be marked as screen reader only if you don't want for the table to be visible to the rest of the users.

Additionally, recently I've been a participant in accessibility studies where charts, diagrams and the like have been structured to be easier to explore with a sr. Those needed js to work and some of them looked custom, but they are also an alternative way to layer data.

Looks good. I wonder what use case Apple has in mind though, or I suppose this is just what the researchers themselves were interested in, perhaps due to the current zeitgeist. I'm not really sure how it works at big tech companies with regards to research, are there top down mandates?

To add things to videos you create with your phone. TikTok and Insta will probably add this soon, but I suppose Apple is trying to provide this feature on “some level”. That means you don’t have to send your video through a social media platform first to creatively edit it (the platforms being the few tools that let you do generative video).

They should really buy Snapchat.

It depends on the context. What do you want to say? How much of it is said in the text? Can the content of the image be inferred from the text part? Even in the best scenario though, giving a summary of the image in the alt text / caption could be immensely useful and include the reader in your thought process.

"VAE: WAN2.2-VAE" so it's just a Wan2.2 edit, compressed to 7B.

This doesn't necessarily mean that it's Wan2.2. People often don't train their own VAEs and just reuse an existing one, because a VAE isn't really what's doing the image generation part. A little bit more background for those who don't know what a VAE is (I'm simplifying here, so bear with me): it's essentially a model which turns raw RGB images into a something called a "latent space". You can think of it as a fancy…

Thanks for the explanation!
