The same reason Intel worked on OpenCV : they want to sell more hardware by pushing the state of the art of what software can do on THEIR hardware.

It's basically just a sales demonstrator, that optionally, if incredibly successful and costly they can still sell as SaaS, if not just offer for free.

Think of it as a tech ad.

I cant see the whole relevant section in the article, but there is a screenshot of part of the legal documents that states "In response, NVIDIA sought to develop and demonstrate cutting edge LLMs at its fall 2023 developer day. In seeking to acquire data for what it internally called "NextLargeLLM", "NextLLMLarge" and-" (cuts off here)
