this fits a pattern: the hugging face deal (\~$12b) and now an open-model lab. nvidia is using its cash to make sure there's always a strong open model that runs best on its hardware, so demand doesn't depend on a handful of closed labs that are all trying to build their own chips.
the tension is that it starts competing with its biggest customers. openai, meta and google are also the ones buying the gpus. a few billion here is nothing next to a \~$5.6t market cap, so the risk isn't the price paid, it's whether customers read it as nvidia moving onto their turf.
