openai/codex SLOC report
As of 2026-09-04 (commit 956aa3f6372f), openai/codex contains 1,839,278 total lines: 1,670,803 code, 33,763 comments, 134,712 blank, across 5,983 files in 23 languages (top: Rust 86.4%). Counted with tokei via OctoCounts.
OctoCounts produced this report by resolving openai/codex to commit 956aa3f6372f, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
