Ask chat completion to respond an empty string if it doesn't have an answer

Prompting
1

With OpenAI.ChatCompletion, I am trying to summarise some titles related to given concepts.
Model: gpt-3.5-turbo
Temperature: 0.8
The rest of the values are default.

My prompt is like this:

Summarise the titles below, which are delimited with triple quotes, about the concept ‘Football’.
“”"
- Messi’s next challenge!!
- Transfer season in UK is just started!!
…(and so on…)
“”"

There are cases that the given text has no relation with the concept, according to API, and it answers such:
- There are no titles related to the given concept ‘Football’.

Instead of such an answer, I’d like to have an empty response. Therefore, I am adding a line in my prompt like:
If there are no titles related to the given concept found, do not output anything.

However, it still keeps returning the generic answer instead of an empty string.

How can I construct my prompt for this?

Instead of telling it not to output, how about telling it to output something (e.g. NO-OUTPUT) in that case? Then just check for it.

I just tried with “EMPTY” meanwhile looking for answers and it worked!

If you want no response from model use “<|im_end|>”
