System message: how to force ChatGPT API to follow it

Similar issue in my post.Ai leaves the role too easily and ignores the “system” content.

I love how “text-davinci-003” is working on my ChatBot examples.
Gpt-3.5-turbo is a lot chaper, and I’d prefer to use it , but text-davinci-003” is working a lot better for using on Chatbot in my experience.
(or maybe I’m doing something wrong) :wink:
