What hardware runs Llama 4 Scout?

Llama 4 Scout is a 107.77B-parameter mixture-of-experts model with 17.17B active parameters (other license). 17B active from 109B total, huge context on paper. Divisive reception; the long-document niche is where it earns keep.

All figures assume an f16 KV cache, a 0.6 GB display reserve on the GPU, and 64 GB of DDR5 system RAM for the offload tiers. Tune these in the calculator.

Quant guidance

Our floor for Llama 4 Scout is Q3_K_M — below that, quality degrades faster than the VRAM savings are worth (large models tolerate low bpw better than small ones, which is why the floor is lower here). Prefer the highest quant that still lands "Fits on GPU" or “Expert offload” at your context length in the table above.

Recommended run command

Q3_K_M at 32K on a NVIDIA GeForce RTX 5080-class GPU (Expert offload):

llama-server -m Llama-4-Scout-17B-16E-Instruct-Q3_K_M.gguf -c 32768 --flash-attn -ngl 99 --n-cpu-moe 48

Frequently asked questions

How much VRAM does Llama 4 Scout need?

At Q3_K_M and 32K context, Llama 4 Scout needs about 56.3 GB of VRAM to run fully on GPU (weights + KV cache + overhead). As a mixture-of-experts model it can also run with far less VRAM via expert offload, keeping experts in system RAM.

What is the smallest GPU that can run Llama 4 Scout?

The NVIDIA GeForce RTX 5080 (16 GB) is the smallest GPU in our set that runs Llama 4 Scout well at 32K context, using expert offload with 64 GB of system RAM.

What quantization should I use for Llama 4 Scout?

We recommend Q3_K_M or higher. Q4_K_M weighs 60.9 GB (4.85 bits/weight); going below Q3_K_M costs noticeable quality on a model this size.

How long a context can Llama 4 Scout handle?

Llama 4 Scout supports up to 10240K tokens. KV cache grows linearly with context.

Can I run Llama 4 Scout without a GPU?

Yes, at reduced speed: on CPU with 64 GB of DDR5 it manages roughly 6 tokens/sec at 8K context (Q3_K_M).
