No site is reliable all the time, even more so if the talk about future products.
With that said, the article you've posted as an example is clearly labeled as a rumor, not a leak or an announcement, and both the DP 2.1 and the TSMC 3nm details came straight from Kopite, who shared them in two tweets featured in the article.
The 384-bit bus memory was the rumor back then, likely also coming from a previous post by Kopite (videocardz link here), who later came up with the 512-bit bus update.
At this point, you may as well say that Kopite is an unreliable source of info which, as a leaker, it's something anyone with common sense should take for granted. There are leakers that get more things right than wrong, and he's one of them, but no one has a 100% correct track record.
As for using AI to write articles and create pics, I didn't know that and it's a shame. If you have better sources for those kinds of leaks, it would be great if you could share them with the rest of us.
