How to Enable AI Feature Flags in Chrome

Prerequisites: You must be using Chrome version 133.0.6848.0 or higher.

You can check your version at chrome://version

  1. Enable On-Device Model Flag

    This flag is necessary to enable so chrome can download Google's Gemini model to run directly in your browser

    Enable this core feature flag and set to ("Enabled BypassPerfRequirement"):

    • chrome://flags/#optimization-guide-on-device-model

  2. Enable Features General AI Flags

    Activate the following feature flags: (activate all for access to the full set of features)

    • General: chrome://flags/#prompt-api-for-gemini-nano
    • Summarization: chrome://flags/#summarization-api-for-gemini-nano
    • Writing: chrome://flags/#writer-api-for-gemini-nano
    • Rewriting: chrome://flags/#rewriter-api-for-gemini-nano

  3. Enable Language Features Flags

    Activate these language-related feature flags:

    • Language Detection: chrome://flags/#language-detection-api
    • Translation ("Enabled without language pack limit"): chrome://flags/#translation-api

  4. Restart Chrome

    Click the "Relaunch" button that appears at the bottom of the screen to apply changes

Note: These features are experimental and may not be stable. Enable at your own risk.

After restarting, check if the AI features are available:

  1. Install AI Components

    Wait for Chrome to download and install the necessary AI components. This may take a few minutes.

  2. Install Translation Languages

    You can install translation languages in one of two ways:

    • Visit the translation internals page: chrome://on-device-translation-internals
    • Or simply attempt to translate text in a new language - Chrome will automatically download the required language pack but you probably need some time to download.
