What OpenAI Codex is, and how its flights are identified
OpenAI Codex is a coding agent made by OpenAI (product page ↗). Codex writes no attribution of its own: flights come from the AIDev dataset’s identification and from codex/ branch names, and a branch prefix alone keeps a flight out of the index until a second signal or the author’s claim confirms it. Every flight on this page is a public pull request on GitHub; outcomes are classified deterministically from the review record — see how the Guild counts and what counts as a flight.
