Utilizing LLMs for Q&A

Hi, I’m wanting to use one of the biomedical LLMs for biomedical Q&A. However several of them including BioGPT seem available only for sentence completion/generation even though the paper says they were tested on Q&A tasks. Even the models that are available for Q&A tasks requires one to provide context data as part of the query (Detailed parameters, microsoft/BioGPT-Large-PubMedQA · Hugging Face). However I want to be able to directly query the model in the form of a direct question. Can someone please assist me with how I may do so?
