I've used Ollama to run Llama 2 (all variants) on my 2020 Intel MacBook Pro - it's incredibly easy. You just install the app and run a couple of shell commands. I'm guessing soon-ish this model will be available too and then you'd be able to use it with the Continue VS Code extension.
Edited to add: Though somewhat slow, swap seems to have been a good enough replacement for not having the loads of RAM required. Ollama says "32 GB to run the 13B models", but I'm running the llama2:13b model on a 16 GB MBP.
