According to Greg Brockman (@gdb), Codex AI code review successfully identified two real bugs that would have been easy for human reviewers to overlook, demonstrating the practical value of integrating AI-driven code review tools in software development workflows. This experience highlights how advanced AI models like Codex are becoming a reliable safety net for every pull request (PR), improving code quality, reducing manual oversight errors, and increasing developer productivity. The adoption of AI-powered code review solutions is creating significant business opportunities for teams seeking to accelerate development cycles and minimize costly bugs, especially in fast-paced, large-scale projects (source: Greg Brockman, Twitter, Nov 3, 2025).
