I had a task with math and programming, so I searched for o1 mini chat, and found site chat4o.ai. There I had a few free questions for o1 mini, I asked it, and result was good, but incomplete. so I’ve bought it (10$/month). Then I continued to work with it, it gave good results, but I also have a problem with this o1 mini. Often I get answers from A.I. which generates sentences which have some characeters lost - both in written human text and in code as well. So I don’t know how to solve it. I now think, maybe this site chat4o.ai is not original o1 mini of OpenAI, or is it original/genuine? In short, where can I get payed o1 mini so it doesn’t “eat” generated characters?
