Pierre is known for Code Storage, a Git-based storage service whose customers include Lovable, Bolt and Amp. OpenAI intends to bring Code Storage's features into Codex. Trees and Diffs already run parts of the Codex app. Customers can keep using the product until then, and Pierre's open-source projects will stay open. Financial terms were not disclosed; the deal remains subject to customary closing conditions, including regulatory approvals.
