I'd be interested to see, what results one would get, using that prompt with other models. Is there much more to ChatGPT Study Mode than a specific system prompt? Although I am not a student, I have used similar prompts to dive into topics I wish to learn, with I feel, positive results indeed. I shall give this a go with a few models.
I just tried in AI Studio (https://aistudio.google.com/) where you can for free use 2.5 Pro and edit the system prompt and it did very well.
