It comes with the Genesis 8 Starter Essentials. When you install Daz Studio and install Genesis 8, newer updates of Daz also includes Genesis 8.1.
Make sure you have Genesis 8 downloaded, usually it comes installed by default but with the new model I'm not sure if they changed it.
Either way, make sure Genesis 8 is added to your account by going to this page: https://www.daz3d.com/genesis-8-starter-essentials
