Llama 3.1 Nemotron 70B Instruct HF — Hardware Requirements & GPU Compatibility

Chat

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.
