OpenAI says heavy Codex users open 70% more pull requests
OfficialLeadDev · reddit · 2026-07-21
OpenAI engineering lead Sherwin Wu says engineers who rely heavily on Codex open about 70% more pull requests than colleagues who don’t, and the gap is widening.
The broader point is that AI has not simply made engineers faster; it has made traditional productivity proxies less reliable. The most valuable work is increasingly invisible to dashboards that mainly count activity.
The takeaway: separate activity metrics from outcome metrics, because AI is pulling them apart.
