Almost All New Code Written at OpenAI Today is From Codex Users: Sam Altman

Steven Heidel, who works on APIs at OpenAI, revealed that the new drag-and-drop Agent Builder, which was recently released, was built end-to-end in just under six weeks. “Thanks to Codex writing 80% of the PRs.”

“It’s difficult to overstate how important Codex has been to our team’s ability to ship new products,” said Heidel.
