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
Existing models from OpenAI etc never return emojis when using the raw APIs unless you ask for it
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.
