what is worse, no alt tags or bad alt tags? genuinely asking as i just assumed any alt tags would be better than no alt tags at all as most folks will go no alt tag route if friction is too high
I know in the context of web dev that it's contextual (e.g. no alt text on a company logo is better than "logo")
On a social platform, where intent and meaning are often baked into the image, bad might be better than none, but probably not by much
maybe? idk. this is a silly/mild example, but the autogenerated alt text for this picture told a different story than what's going on in it (I added the actual description after the auto one). Sometimes people don't take the time to edit it, so people end up getting the wrong idea of what's going on
It very much depends on the labeling model. I’m assuming that the models used to label videos to train txt2video generation are really good. Also video vs image are very different tasks.
Alt text is more than just what the image literally is. It's also the tone, the meaning behind it, and context. The complexities of why you'd use a particular image is a distinctly human experience. When computers can perfectly explain the purpose and context of images I'll retire.
First off this tool doesn't currently work. Secondly AI can't tell you context or the 'why'. I'm not saying you shouldn't use tools to help you write alt text, I'm saying it can't be automated. Plus, if an alt is only describing the 'what' without any info behind the 'why', it's probably bad alt.
Could you give an example of that? Also are you talking about alt text on social media or in some other setting. I’m interested in a situation where an alt text generated by an LLM would fail and why.

AI can’t get context, with LLM being the approach that slightly improves. but even at a minor improvement, there’s the sustainability costs.
