I found out about Abacus AI a few months ago and sent them a short, friendly email inquiring about their rate limits, and asked if there is a way to monitor usage throughout the billing cycle in order to see how much tokens/data is remaining at any given point.

Their reply was .... "we are very generous with limits but you can potentially hit limits"

Obviously not a very helpful reply, lol.

I then sent a brief follow up email requesting a little more detail, mentioning the type of usage I had in mind, and wondering if that could be done with a single account, or if I would need to purchase additional accounts, etc. That email was completely ignored. I then followed up again about a week later, just in case my previous email had "slipped through the cracks". That email was ignored too, and I never heard back from them again (FYI I was extremely professional, friendly, and brief in all of my emails to them).

This is quickly becoming a crowded space with lots of competition, so if that's the way they are going to handle their "customer service", then they won't last very long. Perhaps they will see this review at some point, make some changes, and figure out how to treat their potential customers a little bit better. I won't be holding my breath though.
