A cost analysis of Kilo Code Reviewer running on real open-source PRs from the Hono TypeScript framework. Two PRs (338 lines and 598 lines) were reviewed using Claude Opus 4.6 and Kimi K2.5 to compare token usage, cost, and issue detection quality. Claude Opus 4.6 pulled significantly more context (618K–1.18M input tokens vs 219K–359K for Kimi K2.5), costing $0.73–$1.34 per review versus $0.05–$0.07. Opus caught deeper issues requiring cross-file understanding, while Kimi found more surface-level issues at far lower cost. A mixed strategy using budget models for daily PRs and frontier models for merges to main is estimated at ~$165/month for a 10-person team doing 660 PRs/month.
