Yeah they have more "common sense", though not as much as I'd like. I used to think Opus is big, but after using it a lot, I think it should actually be a lot bigger. The difference from Sonnet to Opus is really noticeable, but the difference from Opus to human (in common sense) is also massive. I expect as the hardware improves, we'll see 3-10x bigger models become the default.

Small models are making great strides of course, and perhaps we will soon learn to distill common sense ;) but subtlety and nuance appear physically bound to parameter count...
