What drives pr review cost
A pull request review carries the diff, the surrounding context, and often the PR description (heavy input, moderate output). Cost scales with PR size rather than with how much the model says, so the expensive reviews are the ones nobody wants to read anyway. Splitting large PRs is a cost control as much as an engineering practice.
For Gemini 3 Flash specifically, that means output tokens cost 6.0x more than input, at $3.00 vs $0.50 per MTok. At this use case’s 8,000/3,000 token split, output accounts for 69% of the $0.0130 per-call cost.
