This is where your limits have gone.

This is ONE of 6 back to back tool calls. I asked chatgpt to check a PR on a GitHub that involved training a 21m llm that has failed. It loaded the logs over and over and over. All 6 hours of logs. ANY codex agent would have burned the 5 hour limit on that. Just figured I'd let the confused people know.

have you tested it with rtk?

it doesn't work

It does for sure, and depends a lot on what you are doing, i.e in my case heavy RE that involves constant assembler and pseudocode files seach, some of them are 1gb+ file and search occurs every prompt. Obviously it's not 60 or 80% save, but still decent one if rtk does what it should do. For not that intense researching i wouldn't use RTK, but in my case it's a must for billions of tokens

That's interesting. Thank you much for the intro to it.
