That's not really that ridiculous. Looking at my ChatGPT stats my biggest day of token usage was 1B tokens (seeing how far Sol Ultra could go on a difficult problem with a quantitative goal and eval harness that it could run on it's own that allowed it to keep going until it succeeded). I blew through my $100 subscription usage in that one day, but with a 80/20 token blend that's $10k in API billing. So, $70k in a week. With the higher cost of Mythos, that's not that crazy. It's more so a testament to how ridiculously marked up API tokens are, or how discounted subscriptions are (who knows which is true)
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.
Definitely not. It was my first time using Sol Ultra, and I did not expect it to run for 12hr+ continuously. Previously with 5.5 I had to coax it to go for longer than a half hour, so I just started a run and forgot to check back in on it. I think I'm learning how to use it more effectively now, and I could see a scenario where that could actually be worthwhile, but it's a bit of a shot in the dark if you let it go that long uninterrupted.
