Without anyone of us actually knowing the details of the collaboration, all we can do is guess, I guess.

> What data would be useful to capture?

Pipe the prompts straight to Meta and I'm sure they'll be able to extract a ton of useful data.

What's the use-case without any human feedback, which I already mentioned?

I don't work at Facebook, so I'm not gonna spend my time doing their work for them or you.

But off the top of my head, classifying the data into various categories and mentions of Facebook/Meta could allow them to derive sentiment about the company based on geographical location, and know where to invest more in changing the sentiment.

Even if this would be a valid suggestion ( I don't think so).

This would be incredible hard to do without IP.

Cloudflare won't forward it and it can be setup as an API. Additionally, IP's on mobile are re-used across users.

That doesn't even sound remotely to a valid indicator for "investments". Definitely not considering the costs to create and update such a model.
