Finetuning Large Language Models LAMINI

Hi,
I have some questions about the concept proposed here between:
prompt_template_with_input and prompt_template_without_input
courses: https://learn.deeplearning.ai/courses/finetuning-large-language-models
Here is the code:
prompt_template_with_input = “”"Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

Instruction:

{instruction}

Input:

{input}

Response:“”"

prompt_template_without_input = “”"Below is an instruction that describes a task. Write a response that appropriately completes the request.

Instruction:

{instruction}

Response:“”"

I still can’t distinguish the concepts between the two prompts above, can someone help me?
