AI coding agents account for 16.9% of commits in median top GitHub AI repo
Start here
An analysis of the full git history of 52 of GitHub's most-starred AI-tooling repositories, covering 324,088 commits, found that in the median repo 16.9% of commits in its last 180 days of activity carry an AI signature, and 21 of the 52 repos sit at 25% or more. The author reports no detectable link between stars and AI-signed share (Spearman ρ = -0.05, p = 0.72). Of the 36,892 signed commits, 85.3% come from Claude, whose tool adds a trailer by default. The author cautions that heavy AI use is concentrated in projects started in 2025 or later, so the sample cannot separate AI use from recency, and that every AI percentage is a lower bound.
