The chip giant on introduced Nemotron 3.5 Lightning, a "lightweight" open-source AI model that companies can download, modify and use without paying Nvidia or seeking permission. It is Nvidia's first open-source model release since Huang called on Washington to avoid restrictions that he argues could undermine U.S. leadership in artificial intelligence. For my first post, I’m sharing a letter @NVIDIA signed on why open models matter. Meta CEO Mark Zuckerberg on Monday published a manifesto calling for American open-source AI models to become the world's best as Meta released Muse Spark, a new coding model. Alongside Nemotron 3.5 Lightning, Nvidia introduced NeMo Switchyard, software designed to determine the most appropriate and cost-effective AI model for a particular task.
