**[OpenAI Live Demo of "App-Free Phone"]** According to a report by Jinse Finance, on June 1st, during the OpenAI Voice Hack Night, a team presented a live demo of an "agentic operating system" designed for phones. All the interfaces demonstrated were "generated on the fly," without invoking any traditional app interfaces. The core concept is "UI as the system": the phone has no traditional apps, and the interface is generated in real-time by a local on-device model, while heavy reasoning tasks are offloaded to cloud-based GPT. Throughout the demo, the developers used voice commands to instruct it to book flights, delete calendar events, check AI news, send emails, and create to-do lists.
