mjpost/sacrebleu AI coding statistics: 40%

of 5 commits in February–September 15, 2026 were committed by an AI agent — a floor, not an estimate

Too little recent activity to publish. Only 5 commits landed in this window, so the percentage is noisy. Repositories below 100 are excluded from the index for this reason.

One person is driving this. The headline number reflects a single contributor's workflow, not a project-wide shift.

02Drivers

What shapes this result

Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.

Assisted or autonomous

2assisted

0autonomous

Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached.

Agent share by month

Peak month: 66.7%. Bars are scaled to that peak, not to 100%.

04Method

What entered the denominator

The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.

Exclusion ledger

Commits in window	5
Merge commits removed	−0
CI / dependency bots removed	−0
Considered	5

Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.
