On Demand Billing (Tokens vs Subscription)

I want to start with saying that I do really like this product from what I’ve used so far. But as someone who doesn’t use AI on a daily basis, but will often blow through the free messages/message limits using free accounts when I do use it to brainstorm or dig into a product. I’d love it if an application like this could let me pay on demand (or upfront for tokens) rather than have to pay a subscription for something i might not use for a few months. Sure t3.chat is much better cheaper than the first party subscriptions but it’d still be nice to not have to be so on top of my billing for the cases where i know I’m not going to be using the service.
