872 million tokens processed — 97.63% of them cached inputs. 5,222 tool calls. 88 issues closed. Zero critical bugs, and several high-severity ones, in a product I had been QA-ing the whole time I built it.
A note before we start. There's nothing exotic in this setup — no Hermes harness, no custom framework. Just Codex and a long prompt. I'm sure a properly configured Hermes run would measure all of this far more rigorously. I just don't think many people have gotten there yet, and I wanted to show what's already reachable without it.
This didn't start as an experiment. It started as nerves.
I was getting ready to run paid ads. Once you start buying traffic, every broken screen costs money — you're paying to deliver strangers to your worst bug. And I had a specific fear: my product runs in multiple languages, and I am not equally fluent in all of them. If something quietly breaks in one locale, I might not notice for weeks. The ads wouldn't stop running. They'd just keep working perfectly, delivering people to something broken.
So instead of clicking around for an afternoon and calling it good, I handed the whole thing to Codex and told it not to stop until it ran out of things to break.
