    Nvidia is building a monster open-source model to sell more chips

    Nvidia is developing Nemotron 4, an open-source model double the size of its current flagship, to take on the world’s best open weights. Led by VP Bryan Catanzaro, the initiative aims to broaden GPU demand well beyond a handful of frontier labs like OpenAI, backed by $28 billion in cloud compute commitments through 2031. Why it matters: Nvidia wants to ensure it doesn't just sell shovels, but shapes the ecosystem to keep everyone buying them.
