Is your feature request related to a problem? Please describe.

Just a suggestion to replace the model in this tutorial from gpt4all-j to phi-2. A smaller model might help new users to follow the tutorial. Can serve as a good first issue for beginner contributors.

Describe the solution you'd like
Replace the model link with https://huggingface.co/TheBloke/phi-2-GGUF/resolve/main/phi-2.Q2_K.gguf and also change the model name in the request to phi-2.Q2_K.

Additional context
I tried running phi-2 on my M2 MBA using the above replacements. Everything works like a charm :)
