Parallax runs parallel code review by models from other labs at under a tenth of session cost.
When a coding session ends, Parallax asks the router for the next best models from other labs and has them review the work for bugs, security holes, dead code, and slow code. The router picks reviewers the same way it picks anything: the strongest models for the job that did not write the code, so labs with different failure modes catch each other's mistakes.
A finding counts only when a test fails on the original code and passes with the fix while the rest of the suite stays green, checked in a throwaway copy of the repository. Findings that pass arrive as a pull request with line annotations on GitHub, and the review runs on short targeted calls so it costs less than a tenth of the session it reviewed.
