Is it possible to fine-tune a model to answer questions given a few answers/links/sources?

Hello from Ukraine!
Now we have a prototype where we fine-tuned the Curie model .
Here is example
(prompt) blabla
(answer) Bla bla bla bla la bla bla bla

We would like to build such a search that would yield not one but few answers, and also to be able to add a link to the article.We tried LangChain for this task. But it’s expensive and not as cool as it seems
We wanted to ask you to recommend us which model to choose, maybe you know of some solutions that would be more suitable for us.

Here is example
(prompt) blabla
(answer1) Bla bla bla bla la bla bla bla +link
(answer2) Bla bla bla bla la bla bla bla bla bla bla +link

We would be very happy for any recommendations
