tl;dr: Nvidia has agreed to acquire open-source AI platform Hugging Face for $12.9 billion, its second-largest deal ever after December's $20 billion Groq asset purchase. Hugging Face CEO Clément Delangue said he approached Jensen Huang over the summer, and the platform will remain open to the broader AI ecosystem. The deal follows a recent hack of Hugging Face and reinforces Nvidia's push beyond chips further up the AI stack.
