Micro & Soft is divorcing Closed AI

From a comment in the thread for the link

”Julia, why not get AI to proof read your an@mynameisnobody79976lysis so that you can refine your ideas? My AI says this: "The video exaggerates Microsoft’s move as a wholesale abandonment of OpenAI, when in reality it’s a diversification strategy—Anthropic’s models did outperform in certain Office tasks, but Microsoft still relies heavily on OpenAI. Claims that OpenAI is “falling behind” or that its market lead is “evaporating” also look overstated in light of today’s news: Nvidia’s unprecedented $100 billion investment in OpenAI secures massive compute infrastructure, reinforcing its long-term strength. In short, competition is intensifying, but rather than OpenAI being dethroned, the landscape is fragmenting—Microsoft is hedging, Anthropic is gaining traction, and OpenAI just locked in a transformative hardware advantage”

Is that really the case and why would Nvidia invest in Open AI? And what lead? Guess its true but I think both Nvidia and OpenAI are over rated.
