NVIDIA's specialized fine-tune of Llama 3.1 70B. It tops many leaderboards for helpfulness and instruction following, significantly outperforming the base Llama model in alignment.

The cheapest GPU that runs Nemotron 70B locally (min 40 GB VRAM) is the AMD Ryzen AI Max+ 395 (96 GB).
Install Ollama then run: ollama run nemotron
Minimum VRAM: 40 GB. For best results use Q4_K_M quantization.
Nemotron 70B needs about 40 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Nemotron 70B Instruct (40 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Nemotron 70B's smallest variant needs about 40 GB, which exceeds a single RTX 4090 (24 GB). Use multiple GPUs, a higher-VRAM card, or Apple Silicon with large unified memory.
Q4_K_M is the best balance of quality and VRAM for Nemotron 70B in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
Install Ollama, then run: ollama run nemotron. This downloads Nemotron 70B and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
