It's currently unclear if my institution can pay for monthly subscriptions, or software with credits/recurring usage limits. However, we can pay for annual subscriptions to software. Perhaps other institutions have similar limitations.
Anyway, I really want to purchase the PositAI subscription, so it would be great if there were additional pricing options, including an annual subscription (maybe with some usage limit that locks you out until your tokens renew at the end of the week, rather than auto-charging after you run out), or a one time purchase of a set number of tokens
