Introduction

The Llama-Primus-Nemotron series builds upon nvidia/Llama-3.1-Nemotron-70B-Instruct through continued training. Following the same methodology as described in the Primus paper, we first performed pre-training on large-scale cybersecurity corpora (over 10B tokens) to obtain Llama-Primus-Nemotron-Base. We then conducted supervised-finetuning and applied DELLA to merge with the original Nemotron, resulting in Llama-Primus-Nemotron-70B-Instruct.

Llama-Primus-Nemotron-Base achieves an 11.19% improvement in aggregate scores across several public cybersecurity benchmarks.

Benchmark Result

Cybersecurity

Metric (5-shot, w/o chat template)	Llama-3.1-Nemotron-70B-Instruct	Llama-Primus-Nemotron-70B-Base
CTI-Bench (MCQ)	0.6900	0.7148
CTI-Bench (CVE → CWE)	0.6590	0.7410
CTI-Bench (CVSS, lower is better)	1.1893	1.0281
CTI-Bench (ATE)	0.3905	0.4540
CyberMetric (500)	0.9380	0.9280
SecEval	0.7177	0.7208
CISSP (Exam Questions)	0.8527	0.8703
Aggregate	3.0586	3.4008 ↑11.19% 🔥

CTI-Bench(CVSS) is scored using Mean Absolute Deviation (lower is better), CTI-ATE uses F1 score, and the others use accuracy. The aggregate score (Agg.) is the sum of all benchmarks, with CTI-Bench(CVSS) negated.

Training Datasets

Pre-training:

• Primus-Seed-V2 (0.457B): An enhanced version of Primus-Seed, enriched with blogs, news, books, websites, Wikipedia, MITRE and Trend Micro knowledge.
• Primus-FineWeb (2.57B): Cybersecurity text filtered from FineWeb-edu-score-2. Link
• Primus-Nemotron-CC (7.6B): Cybersecurity text filtered from Nemotron-CC.

Note: Datasets Primus-Seed-V2 and Primus-Nemotron-CC are not yet open-sourced and are currently under discussion. Feel free to reach out if you're interested.
