As with all other Debian development, we target the 'unstable' distribution for packaging work (similar to git HEAD). Packages eventually migrate from 'unstable' to the 'testing' distribution once they pass certain checks. And when Debian is ready for a new release, 'testing' will basically be tagged as '13 (trixie)'.
Ubuntu periodically syncs their packages from Debian 'unstable', so eventually they will have they same packages that Debian has.
Either way, we realize that running bleeding-edge distributions is probably not for everyone, so we intend to provide backports for both Debian and Ubuntu. Hence why I said earlier that eventually, it shouldn't matter. With "eventually" being sometime in the next few months.
(Site note: our own PyTorch does not yet ROCm support, we're still working on a few dependencies.)
Can I clarify something. If we install a stable release of Ubuntu now, we wouldn't be able to get PyTorch to work with a 7900 XT/XTX? At least not until you've worked your magic and that's made its way to Ubuntu in a few months?
You could still use a version provided by a third party, for example directly from pytorch.org, or a containerized version provided by ROCm upstream [2].

(Apologies I missed your response earlier as this thread suddenly had a lot going on.)
After installing the dependencies using apt go to pytorch's getting started page [1] select Stable/Linux/pip/Python/ROCm and run the command
