OpenAI announced on November 4 that it will acquire Pierre Computer Company, maker of Code Storage and of the open-source Trees and Diffs libraries already used in the Codex app to browse files and review changes. The deal still needs the usual approvals, including from regulators, and until then the two companies stay independent.
