Already the news had been circulated earlierthat Xiaomi has started internal testing with the Android 14 Developer Preview build. In principle, they started with the Xiaomi 13 series, and then the Xiaomi Pad 6 came up alongside it. And this morning they officially announced the start of testing and recruitment.
Xiaomi announced this morning on all fronts the Android 14 Developer Preview testing program. Recruitment is completely open, with no need to comply, as with MIUI 14 beta testing. But there is one condition, and that is that you have to have the phone that you've been nominated for.
[UPDATE]
To do this, you need to open the bootloader of the phone and there is no MIUI 14 interface, only pure AOSP, the simple Android interface. So get started.
Hungarian extract of the full recruitment:

Unfortunately, the description does not specify whether the operation requires an open bootloader. I suspect that it does, unfortunately I haven't received a reply from Xiaomi as of writing this article, but if I do, I'll post it in a comment.
