OpenAI is building an agentic future with its upcoming Chromium-based browser and a new leak confirms GPT Agent integration.
ChatGPT already comes with Agent mode, which uses a virtual machine to browse the web. The vrtual machine is powered by Linux and it works in a cloud environment (Azure).
While Agent mode can do everything for you, it cannot control your browser. It also cannot see open tabs or other browser-related features. But this could change soon.
As spotted by Tibor, OpenAI wiring Agent mode to choose between two execution paths: a remote “cloud/virtual browser” and a first-party local browser (the rumored OpenAI browser).
The hidden “Use cloud browser” toggle plus a user-agent gate that matches “ChatGPT…Macintosh;…Chrome” strongly suggests the feature is enabled only when you’re on OpenAI’s own Mac app/browser, with the fallback being the cloud browser.
That lines up with OpenAI’s docs describing a virtual/visual browser for agents today, and separate reporting that an OpenAI Chromium-based browser is coming.
OpenAI’s help page says Agent uses screenshots of a virtual browser window to click, fill forms, and navigate, i.e., a cloud browser.
Reuters and others reported OpenAI is prepping its own Chromium-based browser, keeping more interactions inside a ChatGPT-style UI.
46% of environments had passwords cracked, nearly doubling from 25% last year.
