Llama 3.1 Nemotron 70B Instruct
Llama 3.1 Nemotron 70B Instruct is NVIDIA's October 2024 fine-tune of Meta's Llama 3.1 70B — post-trained with NVIDIA's HelpSteer2 reward model and RLHF recipe. At release it outperformed many larger models on LMSYS Arena, demonstrating the quality ceiling that careful post-training can unlock from open base weights.

Strengths
- Open weights — inherits the Llama 3.1 community license
- Strong conversational quality — beat several flagship closed models on MT-Bench
- Transparent RLHF recipe using NVIDIA's HelpSteer2 reward dataset
- First-class support in NVIDIA NIM, TensorRT-LLM, and NeMo Framework
Limitations
- Inherits Llama 3.1 community license restrictions, not Apache 2.0
- Superseded by Llama 3.3 70B's own post-training in many benchmarks
- Strength profile narrower than general-purpose — tuned for chat quality specifically
- LMSYS Arena strength doesn't fully generalize to agentic or tool-use benchmarks
Use cases
- High-quality self-hosted chat assistants
- NVIDIA NIM microservice deployments on enterprise infra
- Research comparing RLHF post-training recipes
- Teacher model for synthetic data pipelines

Frequently asked questions
What is Nemotron 70B Instruct?
An RLHF fine-tune of Meta's Llama 3.1 70B Instruct by NVIDIA, released October 2024. NVIDIA used their HelpSteer2 reward dataset to post-train for improved helpfulness and conversational quality.
Is Nemotron 70B better than Llama 3.3 70B?
On chat-specific benchmarks like Arena Hard and MT-Bench, Nemotron was leading at release. Llama 3.3 70B has since caught up with Meta's own improved post-training. For production, either is solid — pick based on licensing fit and NVIDIA ecosystem alignment.
Can I use Nemotron 70B commercially?
Yes — it inherits the Llama 3 community license from Meta, which permits commercial use below the 700M MAU threshold. You also get NVIDIA NIM deployment artifacts as a bonus.
