The only way to describe this is bragging, advertising, or marketing. There are no reproducible processes described. While the diagram of their architecture may inspire others it does not allow for the most crucial aspect of the scientific endeavor, falsification.
There is no way we can know if Google is lying because there's no way to check. It should be assumed that every example has been cherry-picked and post processed. It should be assumed that the data used to train the model (if one was trained at all) was illicitly acquired. We have to start from a mindset of extreme skepticism because Google now routinely makes claims that cannot be demonstrated. When the performance of Gemini in bard is compared to GPT-4 for example, it falls far short. When they release a video claiming to be an interaction with a model it turns out it wasn't anything of the kind.
Ideally no organization would operate like this but Google has become a particularly egregious repeat offender.
