You need to pay for ChatGPT Plus, or sign up for their API (there’s a waitlist).
FWIW, I got API access quite quickly. Applied March 20, got access March 27. My application was only some 2 line bullshit, their example for "why do you want access" rewritten.
I applied March 16 and I'm still waiting.
I got API access to GPT-4 almost immediately too, but I know people who have been waiting weeks. On the other hand, I don't have plugin access on ChatGPT yet, even though I applied for that as soon as it came out. There's probably quite a lot of luck involved.
I'm almost at 2 months of waiting at this point.
Huh, that’s weird. I thought it was simply generally quick. Did you already have a paid account?
Strange. I applied April 6th and still don't have access
