September 2026 AI Development
Snapshot of AI-relevant GitHub activity as of September 2026: AI repo count, solo dev / web launch candidates, AI tool signatures — set against GitHub-wide event counts from GH Archive.
These count what we managed to observe that month, not what exists on GitHub. They move with our collection rate, so a change between months is not a trend. See the sampled share below for the GitHub-wide figure.
SAMPLE AI development share (random sample)
Based on 1,515 repos drawn at random from 2026-09 activity. The ± figure is the 95% confidence interval. GH Archive's event capture for this month is incomplete, so no absolute count is given — the share itself is measured from the sample and is unaffected. A share does not move when our collection rate does, so a slow month does not distort it.
CONTEXT Global GitHub activity (GH Archive)
Note: GH Archive ingestion for this month is incomplete — daily event volume varies up to sevenfold within the month. The values are shown as captured, but they are not comparable to other months, so no month-over-month is derived.
