Seems to fall back to GPT 3 if you haven't got access to GPT 4 API yet

hmm... doesn't seem to be the case, when I provided my gpt-3 turbo key the error message indicates the gpt-4 model doesn't exist.

Change this https://github.com/enricoros/nextjs-chatgpt-app/blob/466a366... to say "gpt-3.5-tubo" and it should work for you

I updated the model in that file, deployed again using Vercel but still same error.

It seems like it's setting gpt-4 here as well: https://github.com/enricoros/nextjs-chatgpt-app/blob/466a366...

But come on, read through the source, look for the issue, I'm sure you can track down at least something :)

Sorry, as soon as posted my comment, I looked again and found the other occurrence. It's quite late here and I just followed your advice blindly :)

Works now.

Hey guys, op here. Merged the PR for 3.5-Turbo support and cleaned up the code (very good observations on all the places 'gpt-4' was hardcoded). Combo box to select the model. GPT-4 will need a 4-enabled key, while 3.5-Turbo will work with any GPT key.
