Dev builds browser-based 'AI operating system' with google gemini for portfolio challenge, because who needs silicon when you've got cloud run

SanjayOS, a revolutionary AI-powered operating system, has been developed by an individual as part of the New Year, New You Portfolio Challenge presented by Google AI. The system, built using Next.js 16, Bun, and Tailwind CSS, allows users to interact with a desktop environment, running terminal commands and dragging windows. The operating system is hosted on Google Cloud Run and utilizes Google Gemini 2.5 Flash, integrated via the Vercel AI SDK. The development process was accelerated by Google Antigravity, an AI-first IDE, which helped scaffold complex window management logic and prototype generative UI components. The system's AI kernel can execute functions and launch applications based on user input, creating an immersive experience. This innovative project demonstrates the potential of AI-powered interfaces and cloud-based deployment, making it a significant development in the tech industry, particularly in the areas of operating systems and user experience design, with implications for future web interfaces.
