Recommendation for AI research. Lightning wallet + an auction type set up. Initially talking to it is free, but as more people ask it stuff and resources need to be allocated, let people pay sats for priority.

Now, barring weird or perverted cases, the people willing to pay will be the people who found previous answers to be valuable. If it's very valuable, you may even be able to ask for an extra fee for privacy, but generally it'd be cool if the answers were here on nostr for people to discover. If people discovered extremely valuable answers just by scrolling through the global feed, then that's good advertising and you'd have more people willing to throw sats at your AI for awesome answers that helped them improve their lives in some way.
