I’m using the action Complete Chat based on a predefined prompt and 3 fields entered in a Form by the user. At the first submission of the form, the response seems ok but if I do other tests, the Chatgpt responses always shorter and end with strange characters repeating several times (sorry screenshot in French). I’ve tested different models (4, 4o), different temperature, max tokens or penalties values, but always the same behavior. Any ideas of root causes and of solutions?

Seems like you’re having a negative frequency penalty in your previous try. That might have increased the likelihood of repetitive words.
