Devin Review 2.0 Cuts PR Review Costs by 82% and Becomes Default Tool

• Devin Review 2.0 is now the default tool for PR review when working with Devin, with costs dropping 82% since August to a typical range of $0.25-$0.75 per review.
• Quality improved alongside cost reductions, with the average number of bugs found per PR increasing from 1.22 to 1.32, while median latency decreased from 139 seconds to 94 seconds.
• Incremental reviews are now enabled by default, focusing on changed parts of a PR to reduce noise and cost, with about 80% of PRs costing less than $1 to review including all pushes.
• New features include Devin Review Ultra for high-stakes code, Custom Reviewers in beta for specialized checks, and automatic review rules that can trigger on every push or filter by file paths and branches.

Integration with Devin

• When used with Devin, the system investigates findings and automatically fixes, dismisses, or escalates issues, leaving only critical decisions for human review.
• Devin Review can be triggered via /devin review comments in GitHub or GitLab, or from the Devin Cloud and Desktop interfaces.

Cost and Performance Controls

• Users can set per-PR spend limits to prevent runaway costs and use fine-grained rules to exclude low-value PRs from automatic review.
• The system supports draft PRs and allows filtering by labels, branches, and specific file paths to optimize spend.
