Google's compact, Pixel 4-like Assistant starts reaching older phones – Engadget, Engadget

To be clear, this doesn’t include everything you’ll find inAssistant on the Pixel 4. It doesn’t have the continued conversation or screen context features, for instance, and it certainly doesn’t share the new look. Familiar interface elements are still there. This is more to reflect Google’s new approach, which treats Assistant more as a background companion than a front-and-center experience. Even so, it’s good to know that you don’t have to buy Google’s latest to get an obvious functional difference this quickly.
