How much does code review cost?
Compare 14 AI models for code review. Prices shown at 10K calls/month with default token counts.
Code review tasks analyze existing source code for bugs, style, and best practices. Input tokens come mostly from the code under review by the model. Output contains structured feedback with specific suggestions for improvement across the codebase.
What drives code review cost
Review is input-heavy in a way generation is not: the diff or file goes in whole, and structured feedback comes back short. That flips the usual optimization: input rate and cache discounts matter more than output rate. Reviewing the same repository repeatedly means the surrounding context is identical call over call, which is exactly the shape prompt caching is designed for.

How much does code review cost per API call?
Review is input-heavy in a way generation is not: the diff or file goes in whole, and structured feedback comes back short. That flips the usual optimization: input rate and cache discounts matter more than output rate. Reviewing the same repository repeatedly means the surrounding context is identical call over call, which is exactly the shape prompt caching is designed for. Across the 14 models we track, a typical call uses about 5,000 input and 2,000 output tokens.
