Why do I get the feeling they are doing the "IBM Watson" thing where different efforts are being put underneath the same brand name?
Not saying it is that egregious, but it's a slippery slope from "well, it didn't do all these different things out of the box, unsupervised".
Gemini refers specifically to a family of multimodal LLMs, which is exactly what they are using here.
They have other models with different names used for different purposes.
