A deep dive into code reviews with Gemini Code Assist in GitHub

Code reviews, often a bottleneck in software development, can be transformed by AI. Gemini Code Assist, integrated into GitHub, offers a solution by acting as an intelligent assistant for pull requests. It provides near-instant summaries of changes, identifies potential bugs and stylistic issues, and suggests improvements. This frees up human reviewers to focus on architectural decisions rather than routine checks. The recently upgraded Gemini 2.5 model enhances review quality with deeper insights and more actionable, context-aware suggestions. Customers like Delivery Hero have reported significant improvements in code quality and developer satisfaction with Gemini Code Assist. The tool aims to make code reviews fast and painless, ultimately leading to higher software delivery performance. Adopting AI in code reviews aligns with DORA research recommendations for faster feedback and improved delivery. Gemini Code Assist is available for free on the GitHub Marketplace.
