HOW WE BUILT OWL, THE NEW ARCHITECTURE BEHIND OUR CHATGPT-BASED BROWSER, ATLAS

Summary from the TLDR AI newsletter

OpenAI built a new architectural layer called OWL (OpenAI's Web Layer) for Atlas, the company's ChatGPT-based browser, to run Chromium's browser process outside of the main Atlas app process. By moving Chromium out of the main application process and into an isolated service layer, OpenAI unlocked a simpler, modern app, faster startup, isolation from jank and crashes, fewer merge headaches, and faster iteration. Development can go faster because most of OpenAI's engineers don't need to build Chromium regularly from source. This article explains how OWL works.
