Peter Yang has rebuilt his entire computer workflow around ChatGPT Work and Codex, using GPT-5.6 as the backbone. The video draws a hard line between three distinct modes: Chat for quick queries, Work for persistent, multi-step tasks with app integrations, and Codex for code execution. He specifies which effort level to use per task type, a practical detail most tutorials skip entirely.
The operational core of the tutorial covers connecting Gmail and Google Calendar so ChatGPT drafts replies in your voice, schedules meetings, and preps briefings automatically. He also walks through scheduled tasks for recurring work and shows how to publish full Sites, including travel guides and interactive games, directly from a Work thread. The custom instructions setup at 03:18 is where the real personalization happens and is worth pausing on.
The full written tutorial is linked for those who want to replicate the setup step by step. What makes this worth reading beyond the summary: the specific model and effort configuration choices at 02:22, and the mobile continuity workflow at 19:23 that keeps tasks running when you leave your desk. Yang also links a free 'No AI Slop' prompt resource on GitHub.
