<action>: What is desired.
create, pull, download, install <model>: Creates a model from local
<model> Modelfile. If that doesn't exist, uses ollama pull to
download the <model> specified.
query, run [model] [input]: Runs a model. Defaults to using
dolphin-mixtral when [model] is not specified. If [input] is not
specified, opens in interactive mode. [input] cannot be the name
of an existing model alone (that would just open the model
interactively). Cannot download a model (a non-existing model
name is treated as input).
help: Print this helptext.
