What OpenAI didn’t tell users openly about its ChatGPT Atlas browser: It is built on …

OpenAI launched ChatGPT Atlas earlier this week, marketing it as “a new web browser built with ChatGPT at its core” that reimagines internet navigation through artificial intelligence. However, the company conspicuously avoided mentioning a crucial detail during its livestream announcement: Atlas runs on Chromium, the same open-source foundation powering Google Chrome, Microsoft Edge, and numerous competitors.

The revelation only surfaced through a support page buried on OpenAI’s website, which states: “Atlas is OpenAI’s Mac browser built on Chromium.”
