UBI doesn't say anything directly about where the money comes from. It's whatever plan you want it to be. (Or more charitably, a family of plans with a common feature.)
You can get any redistribution you like depending on how the offsetting taxes work (if any).
The basic tenet is the "universal basic income" part, the source of funding is not as clear cut. It could be funded by taxes, it could be funded by inflation, it could be funded by something else. Except funding it by inflation long term would probably not be too healthy for the economy as a whole.
"inflationary" is a very complicated concept. It definitely isn't caused by increases in a "quantity of money", as the latter concept doesn't really hold up to scrutiny in the first place.
