# Nemotron 3 Super (120B-A12B)

> The Super variant scales up Nano and adds both latent experts and native speculative decoding support.

| Property | Value |
| --- | --- |
| Lab | NVIDIA (United States) |
| Released | 2026-03-11 |
| Decoder type | Hybrid MoE |
| Family | Hybrid MoE |
| Scale | 120B total, 12B active (10% active) |
| Context window | 1,000,000 tokens |
| Attention | Mostly Mamba-2 with a few GQA layers |
| Layer mix | 8 GQA + 40 Mamba-2 + 40 MoE |
| KV cache / token (bf16) | 8 KiB (Very low) |
| License | NVIDIA Nemotron Open Model License |

**Key detail:** Adds latent-space MoE and shared-weight MTP for fast inference.

## Architecture concepts

- [Grouped-Query Attention (GQA)](https://llm-atlas-7or.pages.dev/concepts/gqa.md): Several query heads share one key/value head, shrinking the KV cache with little quality loss.
- [Latent MoE (Latent MoE)](https://llm-atlas-7or.pages.dev/concepts/latent-moe.md): Routed experts operate in a smaller latent space instead of the full hidden width.
- [Mixture of Experts (MoE)](https://llm-atlas-7or.pages.dev/concepts/moe.md): Many feed-forward experts, but a router sends each token to only a few of them.
- [Hybrid Attention (Hybrid attention)](https://llm-atlas-7or.pages.dev/concepts/hybrid-attention.md): Mixes cheap linear-attention or state-space layers with a few full-attention layers.
- [Multi-Token Prediction (MTP)](https://llm-atlas-7or.pages.dev/concepts/mtp.md): Extra heads learn to predict several future tokens, and can draft tokens at inference.
