Commits that name an AI coding assistant: as their author, as a co-author, or in the line it signs with. These are lower bounds. An assistant that leaves no mark in a commit is not counted, so a share near zero says that commits are not signed, not that no assistant is used. And a mark does not say how much of the commit the assistant wrote.
The share of each quarter’s commits that name an assistant, and under it those commits and all of them. The darker, the larger the share.

Co-authored-by: line names an assistant, as Claude Code, Copilot, Cursor, Codex, Aider and others add when they commit for a person. A review bot whose suggestion was applied is named the same way.Assisted-by: or Generated-by: line names an assistant.Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.
The counts behind this page, for each complete month and quarter the reports cover: ai.json, ai.csv. Each quarter is also kept as it was first published, since commits written in a quarter can still be merged after it ends: Jul–Sep 2026.
