Using installinstallmacos.py to get beta installers

Usually, if you use installinstallmacos.py, you’ll get the already-released installers:

# ProductID Version Build Post Date Title

11 061-26578 10.14.5 18F2059 2019-10-14 macOS Mojave
12 001-36801 10.15.6 19G2021 2020-08-12 macOS Catalina

If you’re in the Apple Beta Software Program (technically, you don’t have to be, but you may want to be to make sure you’re in compliance with Apple terms of use), you can run

sudo installinstallmacos.py --seedprogram CustomerSeed --ignore-cache

And that should get you full installers for beta releases as well:
