The model: `gpt-4` does not exist

[UpsetStarship]

I'm getting this error on Blender v3.4.1 with a paid account I just opened with 0 usage. (It's a "Plus" ChatGPT account with billing tied to the openAI organization as well).

GPT-4:

I have also encountered the same problem. If you manage to solve it, I hope you can update with the follow-up.

Okay so I think there might be a misunderstanding here. You need to upgrade your account to the paid version from https://platform.openai.com/account/billing/overview for GPT-3.5 (GPT-4 is only available via the GPT-4 API Waitlist). ChatGPT plus accounts are not the same and having a ChatGPT Plus account with access to GPT-4 via the web UI will still not give you access to GPT-4 via the API. openai.error.RateLimitError will not trigger unless there is something wrong with payments on your OpenAI account.

so it means people who have subscription and use the plus model still cannot use this addon right now (without changing the original code) and have to wait until full access to model 4 is granted?

You can drop back the GPT model used by this addon to 3.5.

You will just need to add a payment method in https://platform.openai.com/account/billing/payment-methods to get it to work, as GPT API and ChatGPT are currently considered separate products by OpenAI.
It's quite cheap though, I've been using it for various projects over the last few days and I'm still under 50c usage.
