How much RAM is needed for WebUI + v1-5-pruned.ckpt ?

[SurPaul]

I can't run WebUI and some models even with 12 GB of RAM in Google Colab. Last week SD 2.1 worked, but now it doesn't. Only v1-5-pruned-emaonly.ckpt remains. Please see #5878 for more information.

I had to put 32GB ram to avoid problems here

Does this mean I won't be able to use 2.1 models in Colab? Why is the --lowram argument needed then?
