Ask HN: HTML and icon for AI generated content?

I've been making some art content and articles using various AI tools since last summer but I never know what preamble to put on the stuff and so I just say something like generated with whatever.

Does anybody know if there's a font awesome icon or HTML tags or legal guidance from creative commons that can be used as a canonical placeholder for publishing art or generated code or articles using AI. I could find stuff like this:

https://cacm.acm.org/blogs/blog-cacm/263291-on-the-ethics-of-writing-with-ais/fulltext

https://hbr.org/2023/04/generative-ai-has-an-intellectual-property-problem

https://medium.com/@kevin.menear/structured-data-markup-for-ai-generated-content-73b539e92525

But nothing suggesting a style handling disclosure of the AI generation, a tag, an icon, legal marking or anything authoritative that targets both human and computer consumption (crawling, etc.). I'd prefer something easy-to-copy in text or HTML or the like.

Any ideas?

Thanks!
