AI Obsession Fuels YC CEO's 'Cyber Psychosis'
18 Mar
Summary
- YC CEO Garry Tan reports extreme dedication to AI, sleeping only four hours nightly.
- Tan developed an open-source AI coding setup called 'gstack' on GitHub.
- Expert opinions on gstack range from 'sophisticated' to a basic set of prompts.

Y Combinator CEO Garry Tan recently shared his profound excitement for AI agents, describing his current state as "cyber psychosis" with only four hours of sleep per night. He compared this AI-driven fervor to his early startup days, where he relied on stimulants to maintain productivity. Tan has developed an open-source AI coding setup called "gstack," featuring reusable prompts for various development tasks.
The gstack repository, shared on GitHub, quickly gained significant attention, trending on platforms like X and Product Hunt. Tan detailed how his setup simulates an engineering team by using AI for different roles, from CEO-like idea evaluation to code review. This innovative approach has sparked debate, with some hailing it as "god mode" for coding.
However, not all reactions were positive. Some critics argued that the concept of reusable prompts for AI coding is not novel and that Tan's prominence as YC CEO amplified the project's visibility. Experts consulted on gstack offered varied assessments, with AI models like ChatGPT and Gemini acknowledging its sophisticated workflow for simulating an organizational structure, while Claude Code praised it as a mature, opinionated system.
