Findings show that code quality is better across the board and developers felt more confident. Our research found that the quality of the code authored and reviewed was better with GitHub Copilot Chat enabled. Code reviews were more actionable and completed faster. Developers reported maintaining flow state with GitHub Copilot Chat. GitHub Copilot code has been found to be 55% faster. We developed a rubric of five metrics to measure code quality. Using GitHub Copilot correlates with better code quality.
