Hi @TheAhmetIbrahim, thanks for joining the Community!
Ah, yes unfortunately signups for ChatGPT Plus accounts are on hold for the moment. I couldn’t find any details around when OpenAI plans to allow signups to their ChatGPT Plus plan again but for the moment it looks like you’ll need to join OpenAI’s waiting list for that. Not sure if you’ve already signed up to that yet?
If not, head over to your ChatGPT account and click on the Upgrade button. That will open see a pop-up with a Sign up for waitlist button. Clicking that button will then add you to the waiting list:
Sorry to not have a workaround to suggest here, but at present with the ChatGPT app on Zapier you need a paid OpenAI plan for the language and/or image models. And to use the GPT-4 model, you must purchase ChatGPT Plus to access their Plus features, in addition to OpenAI's plans.
If there’s anything else we can help with in the meantime please let us know!
