Hi Yvan,

The Chatbook paclet has been updated several times over the past few months. The latest version is 1.2.4 which was released today, Oct 24. What version do you have?

PacletFind["Wolfram/Chatbook"]

If it is not 1.2.4 then

PacletInstall[ResourceObject["Wolfram/Chatbook"]]

and select "Update".

This may not solve your problem but it is worth trying.

So does all this mean that the Chat functions in Wolfram Notebooks are not available in the free version even if I have a paid version of ChatGPT?

For now we are going to have to just call the Chat enabled notebook a failure

Since chat notebooks worked fine for you with the Wolfram supplied test API key and for many other users (including me), the problem is with the API key you are using and not chat notebooks. Have you tried accessing the API some other way, e.g. Python?

pip install openai

Then execute this Python code after replacing YOUR API KEY with your API key

import os
import openai
openai.api_key = "YOUR API KEY"

completion = openai.ChatCompletion.create(
  model="gpt-3.5-turbo",
  messages=[
    {"role": "user", "content": "What is ChatGPT."}
  ]
)

print(completion.choices[0].message.content)

Just upgraded to 13.3 and I am already regretting it. The hype about the new version was about using chat-notebooks, but this is not enabled by default. I spent quite a bit of time searching for help because the documentation seemed to have nothing. Finally, from this and similar community posts I gather that I need to pay for API to use the main feature touted in the upgrade.

Hey Wolfram people, how about mentioning this in the documentation and glossy marketing brochures?

So far, my experience with 13.3 has been horrible. The interface is a downgrade from 13.1

I assume you entered your OpenAI API key when you used the chat-notebook for the first time. In that case the ChatGPT should work, if not I am in unchartered water..

If you start the Chat-Notebook for the first time, Mathematica should have shown you a separate window with a form to fill in your OpenAI API key. You need to do that again if you use LLMFunction for the first time.

If Mathematica did not show you the form, I assume you can try to re-install the (offending) paclet by uninstalling it first:

PacletUninstall["Wolfram/LLMFunctions"]'
PacletUninstall["Wolfram/Chatbook"]

My assumption seems to backed up here: https://mathematica.stackexchange.com/questions/285713/how-to-use-the-new-llmfunction/285714#285714

Glad to help. OpenAI Sales could do a bit better in communicating their service offerings.

Thanks for sharing the Expression to register your OpenAI API key; I was looking for it too :) Also it saves you the trouble to reinstall a paclet as I (and StackExchange) initially suggested as a work-around.

SystemCredential["OPENAI_API_KEY"]="<YOUR API KEY>";

To check if your API keys have been registered use this Expression:

SystemCredentialKeys[ All]

Enjoy the OpenAI LLM in Mathematica.

Thanks Dave. I did what you suggested but now I get another error:

Had the same. Unfortunately, you also need to set up a paid account for the API. ChatGPT+ account does not work. They bill by the number of tokens used. It is basically only adding credit card credentials. I'd suggest you set up a limit, otherwise, you will wake up with a $120 charge on your credit card (default limit). Mathematica transfers the entire notebook (!) as prompt, so it might get pretty expensive pretty quickly.

From, these notes, putting a ~ in a Notebook makes it fairly easy to partition the history. OTOH, using this technique to limit the consumption of LLM tokens sounds like a less-than-optimal solution.

I fondly hope that, in the future, Wolfram can obviate the need for tokens -- to have the LLM running locally. Between the GPU and the Neural Engine cores and unified memory, there seem to be plenty of untapped computrons on Apple Silicon PCs and iPads. I hope that Apple provides strategic support for WR and others to tap into those resources. Maybe Apple and Wolfram Research will be more closely aligned than they have been in a long time -- I'd love to see Wolfram Research participate in future Apple presentations.
