I don't know. I think he just uses LMStudio most of the time on his, but that's one place I can say the spark really shines for me.

I'm a Linux guy, but also don't always have alot of time. The Spark comes out of the box with a nice Linux distro that's pre-configured to be easy to setup and the guides and online resources make getting up and running trivial, for even some complex tasks. You would have to do a LOT of tinkering just to figure out some of the things the nvidia resources walk you through natively. They have guides for a ton of stuff that include the optimal settings so you don't have to figure it all out through trial and error.

Check out these "playbooks" for some examples. [0] There's a lot to be said for not having to piece all that together yourself.

I think between unboxing mine setting it up to run headless, and generating tokens was like 20 minutes total for me.
