Abstract
Models of open inflation with a variable density parameter provide the most natural way to reconcile an open universe with inflation. The use of anthropic principle is essential to derive observational predictions of such models. I discuss how this principle can be used in a quantitative way to determine the most probable value of . I also comment on recent work by Hawking and Turok on quantum creation of open universes from nothing.
