What changed

OpenAI announced on November 4, 2026, that it will acquire Pierre Computer Company, Inc. (Pierre), the company behind Code Storage and a suite of open-source developer tools. The acquisition aims to expand Codex’s tools for building, understanding, and reviewing code, integrating Pierre’s technologies like Trees and Diffs into the platform.

What this means in practice

The acquisition will allow OpenAI to build on the Git workflows that developers already rely on, adapting them for use with coding agents. Pierre’s tools, such as Trees and Diffs, are already used in Codex to help developers navigate and review code efficiently. The integration of Pierre’s technologies is expected to enhance the functionality of Codex, making it a more robust platform for developers and coding agents. Pierre’s open-source projects will remain open-source, and contributions to these projects will continue post-acquisition.

Limitations and availability

The closing of the acquisition is subject to customary closing conditions, including receipt of regulatory approvals. Until the acquisition closes, OpenAI and Pierre will remain separate and independent companies. Customers can continue using Code Storage after the acquisition closes while OpenAI works to integrate its features into Codex. The exact timeline for the integration and availability of new features has not been specified.
