Sources: Nvidia is developing a Nemotron 4 model with 1T+ parameters, up from Nemotron 3 Ultra's 550B parameters but smaller than leading Chinese open models (The Information)
↗
Nvidia is building a Nemotron 4 model with more than one trillion parameters, roughly doubling the size of its Nemotron 3 Ultra predecessor but remaining smaller than the biggest Chinese open models.
A model of this scale can generate highly realistic text and code, expanding the toolbox available to both defenders and attackers. Because Nvidia is positioning the model as part of its open-source push, the barrier to obtaining a powerful generative engine drops, potentially accelerating the creation of sophisticated phishing, disinformation, or automated vulnerability-exploitation scripts. Security teams will need to update detection and mitigation strategies to account for outputs from a new, widely accessible class of large language models.

Nemotron 4 will exceed one trillion parameters, more than twice the 550 billion parameters of Nemotron 3 Ultra.
The model is still smaller than the leading Chinese open-source models, indicating a competitive but not dominant position.
Running a trillion-parameter model will demand extensive Nvidia-based compute resources, limiting practical deployment to well-funded organizations.
