I'm reading "What is ChatGPT Doing" with the intent of following the examples.

When I try to get the suggested ChatGPT2 from the Neural Net Repository I get an an error message.

NetModel["GPT2 Transformer Trained on WebText Data"]
NetModel::nonetmodel2: No model with name GPT2 Transformer Trained on WebText Data could be found. Did you mean GPT2 Transformer Trained on WebText Data?

When I tried NetModel["LeNet Trained on MNIST Data"] it worked, suggesting I can connect properly.

What is going on here?
