OpenAI announced it will acquire Pierre Computer Company, the company behind Code Storage and the Trees and Diffs developer libraries. OpenAI says those libraries already support file navigation and change review in Codex, and that it plans to bring Code Storage functionality into Codex. The announcement says Pierre’s open-source projects will remain open-source. Closing is subject to customary conditions, including regulatory approvals; the companies remain separate and independent until closing. This is a planned acquisition, not a report that the transaction has closed.
