"Useful" as in "has a use that isn't just for show". It takes me two seconds to read a photo of a water meter. Having an LLM read it for me in 3 minutes isn't useful. Similarly small models are capable of tool use (e.g. web searches) but their synthesis leaves much to be desired. As an example I'd ask some small models to find examples of products with specific characteristics and they'd come back with only one or two because they discounted other possibilities incorrectly by reasoning themselves out of it.

On what do you base this assertion?
