February 22, 2024 Update
The help center articles have been rolled out network-wide. See revision 15 of the February 7th post for more details.
If you're interested in enabling one of these banners on your site, please see the "How can I enable this on my site?" section near the bottom of this post.
February 7, 2024 Update
I've created a separate post to get feedback on changes to an existing help center article, and a draft for a separate new help center article. It will be open for feedback for a week.
January 31, 2024 Update
TL;DR: The Community Team will work on drafting a network-wide Help Center article that explains that AI-generated content is prohibited unless it is posted with appropriate attribution, and then making the “answers must be cited” variant below the default option for all network sites. More details in the coming weeks.
As was pointed out in the comment thread by Joe W (thank you!), our current Code of Conduct (more specifically, its Inauthentic Usage policy) prohibits posting AI-generated content without appropriate attribution (explanation here). With that in mind, it doesn’t make sense that the “answers must be cited” variant, shown below as one of the possible two options for sites to opt-in to, would be optional. As such, we’ll be rolling out the “answers must be cited” option as the default for all Stack Exchange sites in the coming weeks. Sorry for the crossed wires on this, making for a slightly messier roll-out than originally planned.
Since a part of the originally proposed process for sites to request any of the two variants was that they’d need to agree on language for a Help Center article that explains their site’s policy on AI-generated content, before making that rollout, I’ll be drafting a Help Center article that’s supposed to be available on all network sites, and coming back to Meta Stack Exchange for feedback on it before publishing it. The idea is that that article would serve as the bare minimum for all sites, and sites would then be able to further tweak their policy to suit their needs, either by iterating on the “answers must be cited” policy, or by going through the request process laid out below to request the banner be changed to the “not allowed” variant instead.
I’ll make a separate post to gather feedback on the Help Center article draft, but will update this post once that’s up.
January 10, 2024 Update
The experiment has now been graduated, and the banner has been enabled on SO. Please see the bottom-most section of this question for more details on how to request it be enabled on your site.
tl;dr
We’ve recently run an experiment to test a banner highlighting the “AI-generated content” policy on Stack Overflow. Next week we’ll be graduating the experiment that ran on Stack Overflow, and adding functionality to allow the "AI-generated content" policy banner to be enabled on Stack Overflow and all other sites in the Stack Exchange network. The variant group had no significant impact on answer rates; however, it did see a reduction in posts flagged for AI-generated content. Please see the post on MSO for more details on the experiment results.
The banner on SO looked something like this:
Next steps:
All sites in the Stack Exchange network will be able to opt in (the feature is off by default, network-wide)
We will initially offer two banner text options that all sites in the Stack Exchange network can opt-in to. Those options are the following:
**Reminder**: Answers generated by artificial intelligence tools are not allowed on [Site Name]. Learn more
**Reminder**: Answers generated by artificial intelligence tools must be cited on [Site Name]. Learn more
The banner will display once users select the answer field
The “new contributor” banner will no longer be shown in the answer field
All users will see this banner when posting an answer with the option to dismiss. Once dismissed, logged-in users will not see this banner again
"How can I enable this on my site?"
If this is something you think your community is interested in opting into, please start a discussion in its Meta site to get community consensus on the appropriate course of action.
Both options have a "Learn more" link, which will point to a per-site help center article, whose contents should also be a part of the community discussion — this article should explain what the site's policy on AI-generated content is (here's SO's article, as an example).
Once a consensus is reached, escalate it to the Community Management Team by adding the [status-review] tag, so the team can assess the request.
If you have any questions about the process, please post them as an answer below.
