# Lightning-AI/pytorch-lightning SLOC report

> As of 2026-07-15 (commit d710d689510d), Lightning-AI/pytorch-lightning contains 72,390 total lines: 50,493 code, 11,530 comments, 10,367 blank, across 365 files in 8 languages (top: Python 99.4%). Counted with tokei via OctoCounts.

OctoCounts produced this report by resolving Lightning-AI/pytorch-lightning to commit d710d689510d, 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.
