One row for each of the top 20 of 3,490 authors: a square marks each month with commits (bigger means more), and the line runs from their first to their last active month. Bot accounts are grey.
Contributors so far, month by month: each step up is a month in which someone made their first commit.
2,330 of 23,753 commits (9.8%) name an AI coding assistant: as their author, as a co-author, or in the line it signs with. 6 of them were made by an assistant under its own account. In the last 12 months: 2,199 of 12,852 (17.1%).
These are lower bounds. An assistant that leaves no mark in the commit is not counted, and a mark does not say how much of the commit the assistant wrote.

A commit that names two assistants is counted under both.
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.

Lines added over time by the top 20 of 3,490 authors; the top 5 are in color, the rest in grey.
7,961 of 23,753 commits (33.5%) come from an address at 70 organizations, counted by the domain of the address and committed from by two people or more. Domains of one person (most often that person's own), personal mail providers, hidden noreply addresses and bots are counted apart, below.
The domain says where an address is, not who paid for the work: people commit from personal addresses on paid time, and from work addresses on their own.
