The latest public release tag of openai/codex is rust-v0.163.0. This repository provides Codex CLI, OpenAI's coding agent that runs in the terminal. The FACTS contain no changelog for this release, so what changed in rust-v0.163.0 cannot be confirmed. Therefore, this entry covers the tools and usage paths the repository describes rather than any specific feature changes.
Codex CLI is a coding agent CLI that handles code and commands in a local repository on the user's own computer. Command execution has a sandbox and an approval flow. The README explains that it can be used not only in the terminal but also in editors and desktop apps. As installation paths it points to a standalone installer, npm, and Homebrew, and provides binaries for macOS and Linux. You can authenticate with a ChatGPT account or an API key; the implementation language is Rust and the license is Apache-2.0.
However, the provided FACTS contain no benchmarks comparing code-writing accuracy or performance on large repositories. The changes in the latest release are not presented either, so the tag alone is not enough to judge this version's feature changes or quality. The verifiable scope is limited to the purpose of Codex CLI and the execution, installation, and authentication paths stated in the documentation. Whether it suits real work requires separate evidence.
