Estimates from random sample (N=1,515, 2026-09, ±1pt accuracy).
AI development trend
Random sample of N=2,000 from GitHub-active repos per month, classified via GraphQL. Stacked to 100%: built-only / both / using-only / non-AI (grey). AI is the colored slice — the thin bottom sliver of GitHub.
GH-Archive monthly active total (top of stack) plus sample-derived AI breakdown. Stacked: built-only / both / using-only / non-AI. Months where GH Archive under-captured events are left blank, because the absolute figures would shrink with the outage rather than with GitHub — see the ratio chart above.
