Cursor Misrepresents AI-Built Web Browser Project

Cursor recently claimed it built a working web browser using GPT-5.2 agents and roughly 3 million lines of code. Independent developers and the project's engineer reported the repo barely compiles, failing CI, relying on Servo and QuickJS, and showing minute-long page loads; the experiment reportedly consumed 10–20 trillion tokens at multi-million dollar cost. The case underscores a gap between agent-driven demos and production-ready software.
