CodeRabbit is using OpenAI's o3, o4-mini, and GPT-4.1 models to improve code review processes. These models are claimed to boost accuracy, speed up PR merges, and help developers ship faster with fewer bugs and higher return on investment (ROI). The use of these models aims to reduce the time spent on manual code reviews, allowing developers to focus on writing new code. --- Why it matters: This matters because it can significantly impact software development workflows, potentially reducing delays and improving overall efficiency. Developers will be interested in how these models integrate with their existing tools and processes. Source: https://openai.com/index/coderabbit
