My guess is that because OpenAI is the worst of the AI offerings in the industry, NVIDIA is trying to reposition themselves with other companies that are worthwhile.

OpenAI is garbage. It is the household name, but not the go-to solution (in my anecdotal experience).

OpenAI has positioned themselves well as the...Kleenex of AI (where the brand name becomes the sort of...name) but they just aren't good.
