Frequently Asked Questions
- How much VRAM does Llama 4 Scout 17B 16E Instruct need?
Llama 4 Scout 17B 16E Instruct requires 50.8 GB of VRAM at Q2_K, or 119.5 GB at Q8_0.
VRAM = Weights + KV Cache + Overhead
Weights = 108.6B × 3.4 bits ÷ 8 = 46.2 GB
KV Cache + Overhead ≈ 4.6 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q2_K50.8 GB- Can NVIDIA GeForce RTX 5090 run Llama 4 Scout 17B 16E Instruct?
No — Llama 4 Scout 17B 16E Instruct requires at least 50.8 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- What's the best quantization for Llama 4 Scout 17B 16E Instruct?
For Llama 4 Scout 17B 16E Instruct, Q3_K_S (52.3 GB) offers the best balance of quality and VRAM usage. Q8_0 (119.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 50.8 GB.

- Can I run Llama 4 Scout 17B 16E Instruct on a Mac?
Llama 4 Scout 17B 16E Instruct requires at least 50.8 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Llama 4 Scout 17B 16E Instruct locally?
Yes — Llama 4 Scout 17B 16E Instruct can run locally on consumer hardware. At Q2_K quantization it needs 50.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Llama 4 Scout 17B 16E Instruct?
At Q2_K, Llama 4 Scout 17B 16E Instruct can reach ~57 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 50.8 × 0.55 = ~57 tok/s
Estimated speed at Q2_K (50.8 GB)
~57 tok/s~43 tok/s~36 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Llama 4 Scout 17B 16E Instruct?
At Q2_K, the download is about 46.17 GB. The full-precision Q8_0 version is 108.64 GB.
- Which GPUs can run Llama 4 Scout 17B 16E Instruct?
No single consumer GPU has enough VRAM to run Llama 4 Scout 17B 16E Instruct at Q2_K (50.8 GB). Multi-GPU or professional hardware is required.
- Which devices can run Llama 4 Scout 17B 16E Instruct?
