OpenAI uses Codex to migrate 600 petabytes in two months
OpenAI used Codex, a large language model, to help move about 600 petabytes of data and rebuild 10,000 workflows in just two months. Codex generated scripts and checked data as it moved between cloud providers, which may have cut development time by about half. Engineers added approval steps and safety checks at risky points, suggesting that careful human review is still important. The results show Codex-style automation might soon be common in big data projects, but human oversight seems necessary for safety. Error rates were very low, and most problems were fixed quickly, which appears to match or beat usual manual methods.
