With code quality at high effort, the average review now costs just $0.77, down 68% from the $2.43 it averaged over our two most expensive weeks before we started.

So the concrete example here is we do security scanning after on our PRs in local and after our PRs even land because they will always find some things that are real that we have overlooked. And they sort of beat humans on the … code review. And it's expensive. It … us, I think like five bucks a PR or something like that to run all the checks that we want. But that's where we made an explicit decision that it's worth it.

On the cost side, the average review costs $1.19 and the median is $0.98. The distribution has a long tail of expensive reviews – massive refactors that trigger full-tier orchestration. The P99 review costs $4.45, which means 99% of reviews come in under five dollars.

The configuration that catches the most of what our human reviewers catch is also the cheapest one we have run, and most of its budget goes to models that would be dismissed on sight as too weak for code review—which, individually, they are.

Medium effort did lose real findings. In the randomized split, code quality at medium led to roughly a quarter as many acted-on findings as at high, which is why we're moving it to high.

Review has to converge. An agent author and an agent reviewer can keep each other busy indefinitely. One CLI PR went through more than fifty rounds of review and fixes overnight before its author stopped it. When we ran git blame on what the reviewer kept flagging, about 59% of it was code that had been there since the reviewer's first pass.

Before and after the convergence work: pull requests passing after one review and fix round rose from 65% to 78%; pull requests needing five or more rounds fell from 8.9% to 1.5%; mean reviews to pass fell from 2.08 to 1.32.

Noise costs more when the author is an agent. A person can wave off a nit in seconds. An agent fixes it, which means another commit and another round of review.
