I upgraded the llm-gpt4all plugin to support running Llama 3 8B Instruct (thanks, Nomic AI):  
```  
llm install --upgrade llm-gpt4all  
llm -m Meta-Llama-3-8B-Instruct 'Write Python code to print 5 great names for a pet pelican'  
```  
The quantized model is a 4.34GB download and should run on machine with 8GB RAM - works great on my M2 MacBook Pro
