Google is rolling out its Gemini Nano large language model (LLM) directly into the Chrome browser, starting with version 138. This integration aims to bring on-device artificial intelligence capabilities to Chrome's estimated 3.7 billion monthly active users, enabling a new era of local AI processing.
The rollout, which begins with Chrome 138 and continues into subsequent versions, initially requires users to enable specific feature flags for full access. While some advanced features, such as Gemini Live AI within Chrome, are part of a controlled rollout and may require a Google AI Pro or Ultra subscription in certain regions, the underlying Gemini Nano model is designed for broader accessibility.
This on-device integration offers significant advantages, including enhanced user privacy as data processing occurs locally without needing to leave the browser. It also promises faster performance and offline functionality for AI-powered tasks. Key functionalities shipping with Chrome 138 include the Summarizer API, Language Detector API, Translator API, and a versatile Prompt API, allowing developers to build various AI-driven web applications.
The availability of Gemini Nano directly within the browser opens new avenues for web developers. As noted by developer Swyx in a recent tweet,
"Chrome 138+ onwards ships Gemini Nano for every user*, putting a local LLM in 3.7 billion monthly active users of Chrome." Swyx also released a personal guide for building with Gemini Nano, specifically addressing challenges with JavaScript and Google's documentation style, and demonstrating how to achieve structured output using examples from @jxnlco.
Beyond developer-facing APIs, Google is leveraging Gemini Nano for enhanced browser security. The model will power Chrome's "Enhanced Protection" mode, detecting and preventing online scams and suspicious websites by analyzing complex web page content directly on the device. This move underscores Google's strategy to embed AI deeply within its core products for both productivity and safety.
