Take a 2 million line of code repo and ask it to convert from programming language A to B and statically verify every logic flow with an AST for each lang, and then get it to write a test harness that hits 100% code coverage, screenshots every major state and compares screenshots for each state between the old and new. Request it uses an agent team with up to 20 agents. You will use that in a few hours easily.
last 7 days I've used ~4.8B tokens. most of that was during a 2 day span when codex was using one of my harnesses to iterate over a codebase to improve performance of some parts of it - fully automated.

With cache reads and writes and a couple of long running session without /clear or /compact it can get there rather fast
Can do that in a day...
By doing ALL your work in a single chat. The context window explodes.
I typically do one context per feature.
