GitHub's agent pull requests beat human ones in August, near 75 million a month, as Microsoft meters Copilot
GitHub's own count, shared with a keynote by Gergely Orosz, shows agent-written pull requests passed human-written ones in August 2026, near 75 million a month. GitHub had already put Copilot on a token meter in June; Microsoft reports October 27 and Anthropic targets a November listing.

The month the machines took the majority
Agent-authored pull requests on GitHub rose ninefold in eight months, and in August 2026 they outnumbered human-written ones for the first time, on data GitHub shared with Gergely Orosz's LDX3 keynote 1. The run rate is near 75 million fully AI-generated pull requests a month, about three times the 25 million human-written ones the platform carried in December 2023 12. Linear crossed the same line in July: agents now file more issues than people 1.
GitHub stopped donating the volume in June
The crossover month arrived two months after GitHub tore up its own prices 13. Token billing went live on June 1 for Copilot's 4.7 million paid subscribers: monthly plans now draw AI Credits at one cent a credit, while annual plans stay on the legacy premium-request system until they expire 3. Community projections put agentic bills at 10 to 50 times the old flat rate, one from about $29 to $750 a month 3.
GitHub's product chief called the flat rate no longer sustainable, and internal Microsoft documents obtained by Ed Zitron reportedly showed Copilot's weekly running cost nearly doubling since January 3. Satya Nadella has said every per-user business at Microsoft becomes a per-user and usage business 3.
The seat is being shed, not just repriced
The tool vendors are giving up the seat itself. Cursor dropped its IDE interface in April 2026, OpenAI's Codex launched without one in February, and Google's Antigravity 2.0 moved away from the concept in May 1. The lab side already bills this way: Anthropic's prospectus describes revenue from metered token usage and subscriptions 6. The seat side is either repricing to a meter, as GitHub did in June, or dropping the seat's home altogether 13.
Eight model calls per human prompt
Microsoft's own telemetry sizes the load. In the first week of June, 95.1 million human turns became 760.5 million model calls and 774.7 million tool invocations across 3.2 million users, with about 87 percent of the model calls fired by the agent, not the person 4.

|---|---|
| Human prompts | 95.1M |
| Model calls | 760.5M |
| Tool calls | 774.7M |
Reviews became theater under the volume
The bear case sits in the same keynote. With agents throwing far more changes at reviewers, engineers "give up on reviews and just stamp everything with LGTM," one startup engineer told Orosz, and the talk itself lists quality and reliability as visibly down 1.
The maintenance bill is deferred, not priced
The meter also cuts both ways. Failure-retry loops amplify compute by as much as four times, and the customer pays that 4; backlash forced GitHub into bigger allowances, session caps and a 10 percent auto-routing discount, with promotional credits that ended September 1 5. Volume is not profit: Anthropic's prospectus shows about $4.6 billion of 2025 revenue against a $42 billion net loss, much of it a fair-value charge, plus $518 billion of computing obligations 67.

This demand gets priced twice in five weeks
Microsoft reports on October 27, with Azure guided to about 45 percent growth and about $175 billion of calendar 2026 capital spending 8. Anthropic could open its roadshow the week of November 9, seeking $1.8 to $2 trillion and roughly $100 billion of new money 97. The tell is September's bill: the first full month of agent traffic at full meter price, and the first evidence of who keeps paying 5.
