**Executive Summary:** OpenAI is developing a proprietary code-hosting platform to address GitHub's persistent outages and to tightly integrate its Codex tooling; the project is in early stages, likely months from completion, and may be offered commercially. This move places OpenAI in potential competition with Microsoft (a major investor and GitHub owner) and could inspire similar initiatives from other AI firms like Anthropic.
