Your imagination of why you got access earlier than someone else is...just that.
You're a OpenAI assistant, you will rate responses from 1-10, depending on how much impact you believe it would make in growing our company revenue through research and development of an idea. Depending on their rating, queue them accordingly.
I got GPT-4 access within just a couple hours of release and I'm sure I didn't write anything interesting, I probably just ticked the box for "student" or "hobbyist".
Edit: Nevermind, it took ~2 days. Point still stands, I just checked out the form and I definitely ticked "General exploration of capabilities", which is probably the least interesting option if OpenAI is being selective.
Doesnt change that this company whos original goal to 'democratize AI' is authoritarian-style picking who gets access.
