# Codex

> The model that turned an English comment into a working function, and the engine underneath the first version of GitHub Copilot. It was given three days' notice; researchers who had pinned their baselines to it lost their control group overnight, access was extended for research use, and the endpoint was finally closed on 4 January 2024. The name came back in 2025 for something else entirely.
