## The use case: how Graphite deploys Braintrust

Graphite uses Braintrust to evaluate Diamond, its AI code reviewer. They build datasets from real developer reactions to Diamond's comments, run custom scoring functions against model variants, and compare results to decide which models to deploy.

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

> For Diamond's custom rule detection feature, where customers define specific coding standards they want enforced, the team observed a 5% reduction in negative rules generated.

> Braintrust helped us identify several patterns that we wouldn't have found.
