What Chrome is
Chrome is a cross-platform web browser developed by Google. It was first released for Windows in September 2008 and later expanded to macOS, Linux, iOS and Android; it is also the core component of ChromeOS. Most of Chrome’s source code comes from Chromium, Google’s open-source project. Google’s AI assistant Gemini is present in the browser as “Gemini in Chrome”.
Usage and boundaries
- Download and platforms: builds for Windows, Mac, iPhone, iPad and Android are distributed from the official website; Chrome Beta, Dev and Canary channels exist for testing new features early.
- Update cadence: the official site states that Chrome ships a stable update roughly every four weeks.
- Built-in AI: the official site lists Gemini in Chrome and AI Mode search among its AI features; availability, languages and subscription requirements for each feature are governed by the official page. For developers, the Prompt API uses the Gemini Nano model inside Chrome: the model is downloaded separately on first use, runs entirely on the device, and no data is sent to Google or third parties while using the model.
- Account and safety: signing in to a Google account syncs passwords, tabs and settings across devices; features include Safety Check, Enhanced Safe Browsing and a Privacy Guide.
Discussion in the show
In the “本地模型进入浏览器和机器人” (local models enter browsers and robots) chapter of Weekly #001, after a discussion of Perplexity Comet installing local inference models, Yang Pan points out that Chrome has Gemini Nano, a small model that can be downloaded online; Guizang and Orange judge the model too small for real tasks and argue browsers would need to bring in larger local models themselves. These are the participants’ observations at the time. See the Chinese transcript; an English transcript is not available.
