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 Robotics ER 2 specifically, that means output tokens cost 5.0x more than input, at $5.00 vs $1.00 per MTok. At this use case’s 8,000/3,000 token split, output accounts for 65% of the $0.0230 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $1.00 to $0.10/MTok. For repeated system prompts, that saves $0.007200 per call.

Batch API: 50% off all tokens

Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
