My own Chat plugin without access

Hello! I’ve been tinkering with the chatgpt api, using the 3.5 turbo model. Now, since a couple of days, they have allowed me to use the gpt-4 model. I’m also on the plugin waitlist. But I would like to create a simple plugin, something like generating table responses always in json format. The thing is, I don’t know if I could use this plugin or I have to wait to access the plugins.

Correct, you will need to join the plugin waitlist (ChatGPT plugins waitlist) and wait until you get access to use plugins on your account.
