Types are inferred from the sample only. Everything is calculated in your browser; nothing you type is uploaded.
Fields missing from some array items or null in the sample become optional (X | None = None); integers and decimals merge to float; differing types become Any. Python keywords get a trailing underscore.
A user with isActive, an address and a list of orders becomes User, Address and Order models; isActive becomes is_active with alias "isActive".
