GPT without present information // without handling a few pages of data

Dear all,
I cant see the advantage of most GPT`s without access of the present information of www even if it is weather, conditions or something else like a personal trainer without information of present market conditions.
Further the restriction not to handle an input of a few page of input information in GPT is an other restriction which makes it difficult to handle existing information in the process of optimization or feedback.
Can somebody give me what kind of workarounds are possible to handle this restrictions?
Thanks - Chris
