OpenAI sells AI or agent tooling, so it has a reason to publish flattering numbers about AI. The passage stays in the archive; read it with that in mind.
Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-10-31).
The live openai.com page returned 403, so I used the Wayback copy, fetched with curl and stripped of tags. The phrase matches exactly: 'building and shipping an internal beta of a software product with 0 lines of manually-written code'. It is OpenAI's own post. The archived copy is not the live page.

They pull review feedback, respond inline, push updates, and often squash and merge their own pull requests.

This translates to an average throughput of 3.5 PRs per engineer per day, and surprisingly the throughput has increased as the team has grown to now seven engineers.
