## What the story says

Scale uses Greptile as an AI code reviewer that goes first on pull requests, so human reviewers open PRs that already have a score and context. Simple, low-risk diffs that meet a complexity threshold can be included in the next release on a Greptile approval alone.

Summary written by usedby from the source page, in English. The figures are those of Greptile and Scale AI, not ours.

> As code volume climbed and review stayed the bottleneck, Scale rolled Greptile out to ~650 engineers working across Python, Go, TypeScript, and React.

- **100K+**: “Greptile has caught 100K+ bugs.”

> We stuck with it for maybe a few weeks. And I remember we turned it off for a day or two, and we definitely got feedback that hey, I miss that. That was the clear test.
