Is that including cache reads? It seems improbable that (a) you actually filled 1000 1M contexts and (b) OpenAI allowed that in a $100 subscription window.
I don't know, codex does not disclose that information, it just says "1.1B Tokens". OpenAI recently got rid of their 5-hour usage window, so you can burn the entire week in one go, which is what I did.
