Quick Answer: RedHatAI/Meta-Llama-3.1-70B-Instruct-quantized.w4a16 requires a minimum of 35GB VRAM for Q4 quantization. Compatible with 5 GPUs including NVIDIA L40. Expected speed: ~34 tokens/sec on NVIDIA L40. Plan for 32GB system RAM and 100GB of fast storage for smooth local inference.
Llama 3 70B balances top-tier reasoning quality with manageable on-premise requirements. This guide explains the hardware you need to run the model smoothly and how to optimize for your desired quantization tier.
Start with at least 35GB of VRAM for Q4 inference. Scale to higher quantizations as your hardware grows, and pick a build below that fits your budget and throughput goals.

Common questions about running RedHatAI/Meta-Llama-3.1-70B-Instruct-quantized.w4a16 locally
Use runtimes like llama.cpp, text-generation-webui, or vLLM. Download the quantized weights from Hugging Face, ensure you have enough VRAM for your target quantization, and launch with GPU acceleration (CUDA/ROCm/Metal).
Start with Q4 for wide GPU compatibility. Upgrade to Q8 if you have spare VRAM and want extra quality. FP16 delivers the highest fidelity but demands workstation or multi-GPU setups.
Official weights are available via Hugging Face. Quantized builds (Q4, Q8) can be loaded into runtimes like llama.cpp, text-generation-webui, or vLLM. Always verify the publisher before downloading.
