OpenAI Announces Acquisition of Pierre Computer Company to Strengthen Codex Code Toolchain

On November 4, 2026, OpenAI announced plans to acquire Pierre Computer Company, Inc., the operator of Code Storage and maintainer of open-source tools such as Trees and Diffs, both of which have been used for file browsing and change review in the Codex application. Later that week, OpenAI also introduced Pando, a source code backend for engineers and agents. The announcement stated that Pierre's open-source projects will continue to be open source, and Code Storage customers will be able to continue using the service after closing and gradually integrate it into Codex. The transaction is subject to customary closing conditions such as regulatory approvals, and both parties will remain independent until closing. The transaction amount was not disclosed.
