Aside from this just being standard corporate speak copy, there is an element of truth there - the granite models are likely to give you more plain toneless responses rather than a rainbow of emojiis. Which in corporate setting can be useful
That actually sounds nice in theory. A model for getting work done and nothing else, which doesn't have to account or be trained for any type of user engagement. Like how chatgpt/claude are wasting their capacity on social niceties and glazing the user. I don't know if granite is one such but I'd bet that many of the other popular models can't be since they are consumer facing.
