How do i make GPT 3.5 Agents stop thanking eachother?

[AaronWard]

When using gpt-3.5-turbo you may often encounter agents going into a "gratitude loop", meaning when they complete a task they will begin congratulating and thanking eachother in a continuous loop. This is a limitation in the performance of gpt-3.5-turbo, in contrast to gpt-4 which has no problem remembering instructions. This can hinder the experimentation experience when trying to test out your own use case with cheaper models.

A workaround is to add an additional termination notice to the prompt. This acts a "little nudge" for the LLM to remember that they need to terminate the conversation when their task is complete. You can do this by appending a string such as the following to your user input string:

prompt = "Some user query"

termination_notice = (
    '\n\nDo not show appreciation in your responses, say only what is necessary. '
    'if "Thank you" or "You\'re welcome" are said in the conversation, then say TERMINATE '
    'to indicate the conversation is finished and this is your last message.'
)

prompt += termination_notice

Note: This workaround gets the job done around 90% of the time, but there are occurences where the LLM still forgets to terminate the conversation.
