It is really amazing.

With this command “ollama run llama2”, I can run llama2 instantly.

Do you know how much RAM and disk space needed to run this llama2 model?

For disk size, you can see how big models are locally by running "ollama list"

  NAME          SIZE   MODIFIED      
  llama2:latest 3.8 GB 3 hours ago

Now, if you make new models that are "FROM llama2" for example, Ollama will re-use this "base model" so you don't store it twice.

By default the `llama2` model is the 7B model, and it's recommended you have at least 16GB of memory to run it.

Regarding the disk space, the model itself is 3.8GB.
