OpenAI to acquire Pierre, maker of the diff tools inside Codex

OpenAI says it will acquire Pierre Computer Company, whose Trees and Diffs libraries already power file browsing and code review in the Codex app. Pierre also runs Code Storage, a service that lets apps store code and its history using Git, and OpenAI plans to bring its features into Codex. Pierre's open-source projects will stay open source, Code Storage customers can keep using it after the deal closes, and no price was given. The deal still needs regulatory approval, so the two companies stay separate until then. On Hacker News (55 comments), the top reply asks what Pierre even does; others link the deal to OpenAI's Pando Git backend from earlier this week, and one worries open-source updates will slow afterwards. No consensus. Sorted take: if you build on Code Storage, plan for it to move toward Codex; if you only use Codex, expect better review tools.
