openai/codex has 1,665,196 source lines of code out of 1,815,427 total lines across 6,488 files, counted from the main ref at commit 2f3fb111be71 by the OctoCounts tokei engine on 2026-10-22. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.
As of 2026-10-22 (commit 2f3fb111be71), openai/codex contains 1,815,427 total lines: 1,665,196 code, 31,383 comments, 118,848 blank, across 6,488 files in 26 languages (top: Rust 86.7%). Custom configuration (tests excluded, docs excluded, generated excluded). Counted with tokei via OctoCounts.
OctoCounts produced this report by resolving openai/codex to commit 2f3fb111be71, 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.
