Google says Gemini 4 Argon helped split Chrome's legacy code in weeks

Google says its Chrome team used Gemini 4 Argon to separate core webpage handling from a 6-million-line legacy folder in Chromium's 40-million-line codebase, work it says would have taken months.

The company says the split eliminates one category of browser crashes and lets live webpages move between tabs, side panels and floating windows without reloading.

The claims come from a single post on Google's official X account. The post does not include independent verification of the crash reduction or the time savings.
