Summary:

• **What is AI Code Review?** Researchers at Qodo created a tool that uses artificial intelligence to check computer code (the instructions that make programs work) and find mistakes or problems. They built a special test to measure how well their AI tool works at catching errors, just like how students take tests to show what they've learned.

• **Why Does It Matter?** When programmers write code, they sometimes make mistakes that can cause programs to break or not work correctly. An AI code reviewer can help catch these mistakes automatically, which saves programmers time and helps make software safer and better for everyone who uses it.
