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.
How this was checked
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).
Exact match in the page text: "Codex adoption among technical staff is above 92%, Codex reviews every internal pull request, and engineers using it ship about 70% more merged pull requests…". The post is on OpenAI's own forum.
