Cursor CEO Built a Browser Using AI, but Does It Work? (www.finalroundai.com)

Cursor CEO's latest experiment showcases the impressive capabilities of AI in software development by successfully creating a web browser autonomously over a week. Leveraging OpenAI's advanced GPT-5.2 model, which excels at multi-stage coding tasks, the project generated over 3 million lines of code organized into various essential components, such as HTML parsing and a custom JavaScript virtual machine. By implementing a hierarchical management system that divided roles into planners, workers, and judges, the AI agents effectively coordinated their efforts, overcoming previous challenges that led to indecision or trivial changes. This development holds significant implications for the AI/ML community, illustrating the potential for AI to tackle complex projects typically requiring extensive human teamwork and expertise. While the generated browser functions adequately, rendering basic websites, it is still far from matching established systems like Chromium, which consist of tens of millions of lines of meticulously crafted code. The experiment highlights the need for human oversight in project planning and architecture, as well as the importance of maintaining and ensuring the quality of such large codebases. Despite its limitations, the project signals progress in AI-driven coding and suggests that future iterations could leverage these coordination techniques for more advanced applications.
