Do we have to tokenize the question and context together for Q&A models?

Hi all,

I wonder if I can somehow just tokenize the context once and then tokenize each question seperately if it relates to the same context?

I.e. if I have 10 questions that can be answered by the same context, do I have to tokenize(questin, context) each time or could I somehow cache the tokenized context?

Thanks for your help!
