Cognition has made Devin Review, its AI reviewer for code changes, 82 percent cheaper per pull request since August. A typical review now costs between $0.25 and $0.75, according to a post on Devin’s blog dated 5 November 2026, and the company says that is low enough to run the tool on every pull request a team opens.
This is a separate product and a bigger number than the price cut AI Insiders covered in September. That earlier announcement was about Devin as a whole, with Devin Review listed as the biggest saver at up to 70 percent. The new figure is Review alone, measured over the three months since August. Cognition credits a better mix of models and changes to the software wrapped around them.
Cheaper only counts if the reviews stay good, and Cognition says they did. Across the cuts, Cognition reports the average catch rose to 1.32 bugs per pull request, up from 1.22. A gain of 0.1 bug per review is small, and the company gives no breakdown of what kind of bugs those are or how many were false alarms. It also puts the average price of a bug that ends up fixed at about $2.25 across its customers.
Several changes target the bill directly. When a review runs again on the same pull request, Devin Review now looks only at what changed since the last push. Cognition says roughly 80 percent of pull requests come in under a dollar, counting every push, and a per-request spend limit stops a runaway case from piling up charges. Teams can also write rules that skip draft pull requests or filter by file path, branch, or label.
Speed improved as well. The median review now takes 94 seconds, down from 139, which Cognition describes as 1.5 times faster.
Devin Review reads pull requests from any source, but Cognition says it works best paired with Devin itself. In that setup Devin investigates every finding and either fixes it, throws it out, or passes it up to a person, so the developer returns to a list holding only the bugs and calls that need a human. A comment typed into a GitHub or GitLab pull request starts a review, and so do Devin Cloud and Devin Desktop.
Two additions give teams more say over what a review does. Devin Review Ultra is a higher effort level that costs more and digs deeper, meant for places like billing or security code, where a bug that slips through is worth far more than the price of looking. Custom Reviewers, in beta, let a team write its own instructions for checks that are not bug hunts. Cognition runs them on its own code for backend security rules, database migrations, SQL speed, and accessible interface parts.
The pitch rests on a real bottleneck: AI tools produce pull requests faster than people can read them, and Cognition’s own answer is to put an AI reviewer in front of the human. Cognition’s post cites no independent test of its bug-catch numbers.
At the typical $0.25 to $0.75 price, a team that opens 400 pull requests a month would spend roughly $100 to $300 on reviews.
