Nemotron 3 Super is a 120B-parameter open hybrid Mamba-Transformer Mixture-of-Experts (MoE) model from NVIDIA that activates only about 12B parameters per step for maximum compute efficiency and accuracy in complex multi-agent applications. With multi-token prediction it delivers higher token generation than many leading open models.

A standout feature is its very large context window, designed for long-term agent coherence, cross-document reasoning and multi-step task planning. The model is fully open. Weights, datasets and recipes are available. So it can be customized for secure deployment. Through Hormouz it is served behind an OpenAI-compatible API. Point your base URL at Hormouz and drop in a Hormouz key. This is the free tier, well suited to testing and prototyping.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
