On October 22, 2026, Ryan Skidmore shared Cloudflare's internal practices for optimizing the cost of AI code review. According to related reports, the per-run cost of Cloudflare's internal AI code review dropped from $2.43 to $0.77, the median review time fell from 4 minutes 9 seconds to 1 minute 32 seconds, and the number of real issues found in the code quality category remained essentially unchanged. The report states that about 40% of the cost reduction came from engineering changes and 60% from switching models and adjusting reasoning effort, with cross-repository shared cache prefixes being the single change with the largest benefit. Blind evaluation showed that findings with severely overestimated severity dropped from 0.46 per run to 0.14 per run, a 70% decrease. Currently, this practice has been shared publicly by Skidmore, with no further developments yet.
