Beginner: Is GPT plus worth it for academic article summary? And how to best utilize it?

Sorry for the rookie question.
Other more laymen platform to asj such a question like Reddit’s /Chat GPT are temporarily down.
So my question is: Is using paid subscribtion to GPT Plus (GPT-4) good enough for a professional summary (of whatever kind) of an Academic-lengh text article (say 15-30 pages long)? With right prompting can I trust the result?
And if yes, what are you suggestions for the best way to go about it?
(From basic technical detail of how to enter text/article into the engine, lengh limits and how to overcome them, better and effective prompting, and whether automatic prompting is needed to bypass lengh limits).
