In my experience, it usually means Small Block Chevy, but in certain communities it means Single Board Computer, an older way of referring to devices like the Raspberry Pi.

I would elaborate and say, anywhere that your computer is resource constrained ( ram, processing power ) but you still want to make up articles for your Amazon Affiliate blog

In this context I'd assume SBC means Single Board Computer, such as a Raspberry Pi or one of the many imitators. The article itself mentions running LLaMa on a Pi 4.

The interesting implication about running an LLM on a single board computer is that if it's a proof of concept for an LLM on a smartphone. If you have a model that can produce useful results on a Ras Pi, you have something that could potentially run on hundreds of millions of smartphones. I'm not sure what the use case is for running an LLM on your phone instead of the cloud, but it opens some interesting possibilities. It depends just how useful such a small LLM could be.
