Personally, I don’t like the idea of auto-responding due to the risk of annoying our users too much (but maybe we’re spoiled with a decent reply rate to our new topics from our users).
However, I like this use case the most:
We actually have something like this automated with an API for years now, where we reply with a canned reply after 24 hours with no replies on a topic. Being able to have this canned reply augmented with LLMs would be fantastic (as long as there is a toggle to conditionally reply only on unanswered topics after x hours).
