"We haven't figured out pricing" sounds like a big turnoff for anyone seriously considering this who wants self service.
Just pick something that's a no brainier for people to try, change it later if you have to. Your biggest risk right now is people walk without giving the product real consideration. Lack of clarity on pricing will do that for a lot of people, even though you are offering a free trial.
Thanks for the advice. One challenge for us will be how to price-in token based costs, e.g. downstream GPT services. There was an interesting post earlier today on HN related to this https://news.ycombinator.com/item?id=43186032 which recommended progressive pricing, which I thought was really interesting. On the other hand, the marginal cost of these services is being aggressively driven down by the big players so it may ultimately be safe to provide a fixed cost subscription model.
Have you thought about carving out the token expense? I.e. giving users the option of using their own api key vs you being the middle man for that expense?
