Seems like they finally got some activity over https://bonfire.cafe/

I don't understand what exactly this is as it doesn't go into great detail especially the whole "flavors" thing. There's Ember, Social, Community, and Corporation so what's the difference between each. in the documentation for installation it tells you to pick a flavor but again doesn't describe what each "flavor" actually is.

So is this like meetup or some kind of neighborhood app/social group thing? I'd be willing to set up an instance on my server of it today but I don't even know what this really is.

Also they have some art for those that participate:

The code is a commons, so art is offered as a reward. This campaign includes a limited‑run, hand screen‑printed artwork by Rocco Lombardi, the artist behind Bonfire’s icon and other illustrations.

Gave them some cash.

TLDR

Just if you interested about AI/LLM involvement.
There is a AGENTS.md file,
no explicit rules about AI/LLM yet.

However, as suggested above, if the project is founded by the NLnet,
it must adhere to NLnet GenAI policy.
