FAQ
Can Nvidia GeForce RTX 4070 (12GB) run Llama 4 Scout?
No. Llama 4 Scout needs ~64.2 GB even at Q4_K_M, but Nvidia GeForce RTX 4070 (12GB) only has ~11 GB usable.
How much memory does Llama 4 Scout need?
Nvidia GeForce RTX 4070 (12GB) does not have enough memory. At Q4_K_M the weights are ~60.87 GB; with KV cache and runtime overhead, budget ~64.2 GB at a 4k context. It is a Mixture-of-Experts model (109B total / 17B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Llama 4 Scout on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.
