ChatGPT randomness for specific time

Hello,

I hope you are keeping well. We are seeing random answers from ChatGPT for some specific time (for ex. During PST night hours it works properly and responds with proper responses. However, for daytime, it responds badly). We are using function calls and the GPT-3.5 Turbo model. Many times, in the daytime, it even responds wrongly for function and sends even wrong parameters. The same queries work perfectly for night-time. Let me know if we can resolve this kind of behavior.

P.S. We are already using the temperature parameter and has been set to 0.1.

Regards,
