Code review of two comment mark. >> Hey everyone, I'm Roma >> and I'm Maya. >> Codex needs to do two things really well to be an effective coding teammate.First, it needs to work with all your tools and second, it also needs to plug into all of your team workflows. Code review is one of the most important workflows for any engineering team and we want to help there as well. With GPT5 and now GP5 codeex, we train these models specifically to find bugs and investigate some issues.Maya, why don't you tell us m ...

[Music] Thank you all so much for coming to this talk. Um, thank you for being at this conference. Generally, my name is Tomas.I'm one of the co-founders of Graphite and I'm here to talk to you around AI power entomology. If you don't know, entomology is the study of bugs. It's something that we do.We is very near and dear to our heart and part of what our product does. So, Graphite, for those of you that don't know, builds a product called Diamond. Diamond is an AI powered code reviewer.You go ahead, you u ...

Industry Trends - Software development has two loops: an inner loop focused on development and an outer loop focused on review [1] - AI adoption is increasing among developers, with nearly every developer surveyed using AI tools [2] - 46% of code on GitHub is being written by AI, indicating a significant shift in code generation [3] - The inner loop is changing due to AI, making developers more productive and producing higher volumes of code [3][4] - The outer loop is becoming a bottleneck as developers have to review, test, merge, and deploy higher volumes of code [5] Graphite's Solution (Diamond) - Graphite aims to create a new outer loop to address the challenges posed by increased code volume [6] - Graphite's AI code review platform, Diamond, focuses on high signal, low noise, deep understanding of codebase and change history [13] - Diamond summarizes, prioritizes, and reviews each change, integrating with CI and testing infrastructure [13] - Diamond aims to reduce code review cycles, enforce quality and consistency, and keep code private and secure [13] - AI-generated feedback from Diamond's comments are accepted at a 52% rate, higher than human comments (45-50%) [15][16]
