Can AI generate code review comments on production pull requests ?

GitHub Copilot Workspace, Sourcegraph Cody, others — most modern engineering teams use AI-generated review comments as a first pass.

AI can generate code review comments on production pull requests to some extent, using machine learning models trained on large datasets of code and review comments. These models can learn to identify common issues and suggest improvements, such as pointing out syntax errors or proposing more efficient algorithms. However, the quality and relevance of generated comments can vary greatly depending on the complexity of the code, the specific requirements of the project, and the quality of the training data. The use of AI-generated code review comments is still a developing area, with many companies and research institutions exploring its potential to improve the code review process.
