Llama 3.1 Nemotron 70B Instruct HF — Hardware Requirements & GPU Compatibility
ChatFunctions
Llama 3.1 Nemotron 70B Instruct is a 70-billion parameter chat model by NVIDIA, created by applying reinforcement learning from human feedback (RLHF) to Meta's Llama 3.1 70B base model. NVIDIA's Nemotron training pipeline focuses on improving helpfulness, accuracy, and response quality beyond the standard Llama instruction tuning. The model requires substantial VRAM for local inference, typically needing multi-GPU setups or high-end professional GPUs. In quantized formats it becomes accessible on workstation-class hardware. It is available in Hugging Face Transformers format and is supported by popular inference engines.

Frequently Asked Questions
How much VRAM does Llama 3.1 Nemotron 70B Instruct HF need?
Llama 3.1 Nemotron 70B Instruct HF requires 43.3 GB of VRAM at Q4_K_M, or 142.1 GB at BF16. Full 131K context adds up to 42.3 GB (85.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Llama 3.1 Nemotron 70B Instruct HF?
