AI-assisted PR pipeline nearly doubles merges: 353 to 684, before vs after

HanchungLee · x · 2026-09-08

mikejulian published before/after metrics for an AI-assisted PR pipeline: weekly merged PRs rose from 80 to 154 (+94%), totals from 353 to 684; merges within 1h went from 28% to 45%, within 24h from 76% to 80%. Median merge time with human review is 26h; without, 1h.

Responder HanchungLee corroborates with DORA-style metrics: with AI plus human PR reviews, his P90 time-to-merge is lower, fewer than 10% of merges get human comments, time to first human review approaches zero, and change failure rate and recovery time stay steady.
