NVIDIA Nemotron 3 Super 120B A12B is the high-capacity MoE variant of the Nemotron 3 family, delivering strong reasoning and long-context performance for demanding text generation and agent workflows while preserving MoE compute efficiency.
A hybrid Mixture-of-Experts reasoning model that punches far above its active parameter count, running on just 12 billion active weights while drawing on the depth of 120 billion total parameters. Built for the realities of production-grade agentic systems.
nvidia/nemotron-3-super-120b-a12bhttps://api.aimlapi.com/v1NVIDIA's Nemotron 3 Super 120B-A12B is part of the third generation of the Nemotron open model family, a series engineered specifically for building specialized, reliable AI agents rather than serving as a general-purpose chatbot. The "Super" designation marks a meaningful architectural step up from the lighter Nano variant, introducing several capabilities that simply weren't present before.
NVIDIA achieved this through their LatentMoE approach, where expert routing happens in a compressed latent space rather than full model dimensionality, meaning the system is smarter about which experts to engage, not just how many.
Tokens are first projected into a compressed latent space for expert routing and computation. This reduces the byte cost per unit of model intelligence, you call 4 experts but pay roughly the compute of 1. It's what makes the 12B active parameter count feel much larger than it is.
Rather than relying purely on attention, the model interleaves Mamba-2 state-space layers with selective attention blocks. Mamba-2 handles long-range context efficiently; attention handles local precision. The combination is faster than a dense transformer at long contexts.
Unlike models that predict one token at a time, Nemotron 3 Super uses MTP layers as a native speculative decoding mechanism. This is what drives the 167+ tokens/sec output speed, it's not just hardware, it's baked into the model weights.
The Super model is the first in its family pretrained at NVFP4 precision rather than using it only for post-training quantization. This allowed training on the full 25T+ token corpus more efficiently without sacrificing the quality typically expected of BF16-trained models.
Not just a theoretical maximum, the model outperforms both GPT-OSS-120B and Qwen3.5-122B on the RULER benchmark at the full 1M token setting. This matters for agent workflows where conversation and tool-use history must stay in context across hundreds of steps.
This model is documented as suited to agentic workflows, including collaborative agents and multi-agent applications.
It is also documented for high-volume workloads such as IT ticket automation.
It is documented for RAG systems, including retrieval-augmented generation and full-document retrieval workflows.
It is documented for complex instruction-following and long-context reasoning tasks.
