If you are referring to this post, the range mentioned is 60-80% but those numbers are very misleading in my opinion for the reasons detailed here. …so, I would take them with a pinch of salt.
I don’t believe there are any meaningful broader stats about AI/CV accuracy shared on the forum at present.

It increased from 25000-38000 in the update last summer - more details are visible on this blog post.
