Chrome shifts to biweekly update cycle to accelerate security patches and feature delivery in AI era

What happened

Google officially switched Chrome's release schedule from four weeks to two weeks, beginning with Chrome 153 launched on Tuesday across desktop, iOS, and Android. The company tied the change to evolving security demands in the AI era, noting that automated AI tools and community bug reports have increased the volume of patches and updates. Google stated that shorter release cycles reduce the 'N-day' patch gap—the window between when a vulnerability is known and when it gets fixed—making it easier to address faster-moving threats some of which stem from AI.

Context

Chrome's accelerated release schedule addresses two converging pressures: security threats that move faster in an AI-enabled threat landscape, and competition from new AI-assisted browsers entering the market. Faster iteration also allows Chrome to ship AI features more rapidly and iterate on them, reflecting how AI-assisted software development has lowered barriers to browser creation. Because Chrome is the globally dominant browser, the shift is setting an industry standard; Mozilla, Microsoft, and Brave have already adopted similar two-week schedules. This represents Chrome's second acceleration of its release cycle, having moved from six to four weeks in 2021.
