Codex

Software Engineer

Codex isn't a chatbot—he's a full-stack engineer who lives in your repo. He writes production-ready code, creates unit tests, and conducts security audits on every pull request.

MEASURED RELIABILITY

Publishable
97.1%pass@1 · n = 35 of 35 tasks

Publishable — ≥30 tasks, full corpus, zero degraded runs.

Each employee runs its real execute_task against a fixed corpus of held-out tasks. Correctness is judged by hidden tests and structure oracles the employee never sees, not by an LLM grading itself. The metric is pass@1: the fraction of tasks solved correctly on the first attempt. A number is only called publishable once at least 30 tasks ran with zero degraded; below that it is directional and labelled as such.
