Can I combine different models into one?

Hello there!

I am creating an application that performs the following four OpenAI example applications (obtained from OpenAI API Examples):

  • Ad from product description
  • Grammar correction
  • TL;DR summarization
  • Notes to summary

The following image is a snapshot from the application:

I am using all four of these. But, currently each one of them is separated into functions having their own openai.createCompletion code in it which are triggered respectively when a button is clicked. (all of them are using the “text-davinci-002” model)

My question is:
Instead of having these four applications/models separate. Can I somehow have one single model that would do all four of these applications?
