I think this is a classic [Commoditize Your Complement](https://news.ycombinator.com/item?id=17047348) - Nvidia wants open models because their business is hardware and it's complement is AI models, so they want AI models to be commoditized so that hardware is the industry with leverage. OpenAI/Anthropic/etc want closed models so that the AI model development/data has leverage over the hardware providers.
