Earlier quoted context omitted.
I remember vividly that the focus on GPT-4.1 to speak more humane and be more philosophical when speaking. I remember something like that. That model is special and is not meant like a next generation of their other models like 4o and o3. You should try a different model for your task.
I think you're confusing GPT-4.5 with GPT-4.1. GPT-4.1 is their recommended model for non-reasoning API use.
You are right!
