I think another key thing to call out is even with all these defenses, community notes are incorrect sometimes.

Now, because it is really rare, we actually get this self-correcting property where the incorrect notes attract a lot of attention, and they'll draw a lot of raters to go quickly rate them not helpful, and then they'll stop showing.

And I think that self-correcting property is super important also just in a breaking news situation, right?

Something that was true a few hours ago may not be anymore.

So it's great that notes are not set in stone.

Yeah.

Well, first, just to level set on speed, I think Keith already mentioned, the previous state-of-the-art fact-checking would often take on the order of days, and community notes is usually more on the order of hours.

So it is already quite a bit faster.

Notes can appear as often as about 20 minutes on a brand-new post, but they can actually appear instantly if there's already another note out there that's matching on a URL or image or video.

I think on top of that, one thing that people really, really like is...

if someone actually sees a post and engages with it before a community note is appearing, we'll actually send them a push notification later, so they get the correction as soon as the note comes out.

Now, even with all that, I think it's super important for us to keep making community notes faster.

People want instant context, and rightfully so.

So to that end, what we've done last year is we've actually opened up an open API for AI contributors.

And this is a little bit of a crazy thing.

In the totally open spirit of community notes, just like a regular person can be writing notes, we let regular people write their own AI note writers and submit notes to our system.

And what we've seen so far is

It's actually working really well.

The notes are really fast and they're quite good.

But definitely, because it's AI, they're wrong some of the time.
