Google recently began rolling out the Android 16 QPR3 Beta 2.1 update to eligible Pixel devices. At the same time, the company has confirmed that the first Android 17 beta is coming soon. In a Reddit post, Google revealed that the Android 17 Beta 1 will roll out to users soon with bug fixes and include improved performance and system stability.
An open beta program has seemingly started, but you can't just get in. Instead, you need to pass an eligibility quiz. You reach this by going to Settings > System & update > Software Update then hitting the three dots and choosing Beta Program. This should work if you have a OnePlus 13, OnePlus 13R, OnePlus 13s, OnePlus Open, OnePlus 12, OnePlus 12R, Oppo Find X8, or Oppo Find X8 Pro.
