## Benchmark scores published at release

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| LiveCodeBench | 68.3% | Lab | Coding problems published so recently the AI can't have seen them in training — a contamination-free test of raw programming skill. Higher is better. |
| GPQA Diamond | 73% | Lab | Graduate-level science questions in biology, physics, and chemistry — hard enough that subject-matter PhDs score around 65%. Higher is better. |

## About Nemotron 3 Nano

Nemotron 3 Nano, released December 15, 2025, opened NVIDIA's first fully in-house Nemotron generation — no Llama base underneath — and made the architectural bet explicit: a hybrid of Mamba-2 state-space layers, mixture-of-experts feed-forwards and a small number of attention layers, with 30 billion total parameters and roughly 3.5 billion active per token. The design traded a little per-token capacity for throughput on long agentic transcripts, which is what NVIDIA said models would spend 2026 doing.

Its launch card reported 73.0% on GPQA Diamond, 68.3% on LiveCodeBench and 89.1% on AIME 2025 without tools — unusually strong mathematics for the size — and the release was open in the fullest sense the industry used: weights, the bulk of the datasets and the training recipes all published. Super and Ultra tiers were promised for 2026 and arrived in March and June of that year.
