Tutorial: Chrome built-in AI

Chrome built-in AI

Chrome is experimenting with adding built-in AI directly to the browser, allowing websites and web applications to perform AI-powered tasks without needing to deploy or manage their own AI models. Please follow the steps below to use Chrome’s built-in AI:

  1. Install Chrome Canary: Ensure you have version v128.0.6545.0 or newer.
  2. Enable Optimization Guide: Open chrome://flags/#optimization-guide-on-device-model, set it to "Enabled BypassPerfRequirement".
  3. Enable Prompt API: Open chrome://flags/#prompt-api-for-gemini-nano, set it to "Enabled".
  4. Relaunch Chrome.
  5. Open DevTools and send await ai.languageModel.capabilities().available; in the console. If this returns “readily,” then you are all set.
  6. If it fails, force Chrome to recognize that you want to use this API. To do so, open DevTools and send await ai.languageModel.create(); in the console. This will likely fail, but it’s intended.
  7. Relaunch Chrome.
  8. Open a new tab in Chrome, go to chrome://components.
  9. Confirm that Gemini Nano is either available or is being downloaded. You'll want to see the Optimization Guide On Device Model present with a version greater or equal to 2024.5.21.1031. If there is no version listed, click on "Check for update" to force the download.
  10. Once the model has downloaded and has reached a version greater than shown above, open DevTools and send await ai.languageModel.capabilities().available; in the console. If this returns “readily,” then you are all set.
