How much does an AI code-review bot cost per pull request?
Figuring out how to estimate an AI code-review bot's cost per pull request is one of the first budgeting questions AI teams hit. Built for platform and DevEx teams, this tool skips the generic rate card and gives you a working estimate you can tune to your traffic. The result reacts live as you adjust the inputs.

Why this isn't trivial
The part people underestimate: large diffs and surrounding file context make each review input-heavy, and big PRs cost far more than small ones. In practice the biggest savings come from reviewing only changed hunks with minimal surrounding context, so it is worth modelling before you commit.
How it's calculated
We estimate this by counting the tokens in a typical diff plus context and applying model rates per pull request. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Should the bot read whole files?+
Usually just the diff plus a little context; whole-file reads inflate input cost.
Which model for code review?+
A strong reasoning model helps, but mid-tier models handle routine reviews cheaply.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
