"This particular [80B] model is what I’m using with 128GB of RAM". The author then goes on to breezily suggest you try the 4B model instead of you only have 8GB of RAM. With no discussion of exactly what a hit in quality you'll be taking doing that.

This is like if an article titled "A guide to growing your own food instead of buying produce" explained that the author was using a four-acre plot of farmland but suggested that that reader could also use a potted plant instead. Absolutely baffling.
