The kernel drivers are all published in the GrapheneOS kernel repositories. A subset of the libraries/services in the vendor partition used with those drivers are closed source.
Pixels were headed towards all of the device support code for the OS being open source along with open sourcing large portions of the firmware including for the TEE (Trusty OS) and secure element (OpenTitan). It was ended after the launch of Android 16. It's a major factor in why GrapheneOS is going to be focused on future Motorola Mobility devices. You can still see a large portion of the Pixel userspace driver libraries and services in the AOSP source tree but they stopped pushing new releases for a lot of it.
