Hi, I need to generate a lot of responses so I’m using the API. I have started off with a balance o f 6 USD to test the usage and all the details. I set up some python code to generate some responses. I was looking at the 73k tokens of 4o and around 4 k tokens of 3.5. turbo Yet, I was billed 2.5 USD. What am I missing? I thought it was like a million tokens of input allowed or something like that.
