Question on fine-tuning

I’m trying to fine-tune a model for basic categorization

eg:

Apple->Fruit
Cucumber->Vegetable
Pork->Meat

Should i train the model with these lines?, eg:

{"prompt": "Apple ->", "completion": " Fruit\n"}

Where would i put the context/instructions for a prompt when fine-tuning?

eg, in the playground i would write:

The following is a list of foods and their categories:

Apple->Fruit
Cucumber->Vegetable
Pork->Meat
Banana->

Also, once the model is fine-tuned… do i always need to put the instructions (The following is a list of foods and their categories) into the prompt? It costs tons of credits to do so… Or do i just put

Banana ->

there ?

You can put this into the fine-tuned model:

And in your app you can request the API with such prompt:

Determine the category of the following food: apple →
The category:

Is just an idea.
