Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

On record

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

The extremes

The ten fastest GPUs for Llama 4 Scout

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run Llama 4 Scout

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

What it takes to run this model

Minimum card

Radeon Instinct MI200

Memory needed

54.0 GB

Fastest

31.1 tok/s

Llama 4 Scout sits at 109B parameters, which puts it above consumer hardware and into the range where a card is bought for this purpose rather than repurposed for it. 43 of the cards we track can hold it.

The smallest card that holds it is the Radeon Instinct MI200 with 64 GB, running it at Q3_K_M and producing around 13.4 tokens per second.

A B200 is the fastest we calculate for it: about 31.1 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

Llama 4 Scout was published by Meta AI, in United States of America, in April 2025. industry is the category the publisher falls under.

It works in Multimodal, Language, Vision, and is recorded as doing chat, Code generation, Visual question answering, Language modeling/generation, Question answering.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded. It is published under the meta-llama organisation on Hugging Face.

How fast it runs, and why

Half the cards that hold it manage more than 18.2 tokens per second, and 39 exceed reading speed outright.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

How it was trained

The training run consumed about 4.1 × 10²⁴ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

The training set ran to roughly 30,000,000,000,000 tokens.

The reason it appears in this catalogue at all is discretionary.

Step by step

How to choose a GPU for Llama 4 Scout

The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.

01

Read the memory figure first

The table lists every card that can hold Llama 4 Scout — around 54.0 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Set the context length you will work at

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Llama 4 Scout.
03

Decide how much compression you will accept

Compression is what makes Llama 4 Scout fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Rank by throughput rather than spec sheet

The speed ordering for Llama 4 Scout is effectively an ordering by memory bandwidth, which is why the B200 tops it at 31.1 tok/s.
05

Check the fit verdict before buying

Tight means Llama 4 Scout loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.
06

See what else that card runs

Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for Llama 4 Scout alone — a card is usually bought for more than one model.

Answers

Llama 4 Scout — common questions

How much VRAM does Llama 4 Scout need?

About 54.0 GB at Q3_K_M compression, which is what the smallest card that runs it uses. Less compression needs more: the figures in the memory column above are recalculated for each card, because each one holds the least-compressed version it can.

Is Llama 4 Scout open source?

Its weights are published, so Llama 4 Scout can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

How many parameters does Llama 4 Scout have?

Llama 4 Scout has 109B parameters. "Our smaller model, Llama 4 Scout, is a general purpose model with 17 billion active parameters, 16 experts, and 109 billion total parameters that delivers state-of-the-art performance for its class.". That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

Who created Llama 4 Scout?

Llama 4 Scout was published by Meta AI, based in United States of America, categorised as industry.

When was Llama 4 Scout released?

Llama 4 Scout was published in April 2025.

What is Llama 4 Scout used for?

Llama 4 Scout works in Multimodal, Language, Vision, and is recorded as handling chat, Code generation, Visual question answering, Language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Llama 4 Scout?

Its weights are published under the meta-llama organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.

How much compute was used to train Llama 4 Scout?

Around 4.1 × 10²⁴ FLOP. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.

Can I run Llama 4 Scout if it does not fit in my GPU?

It can be split between the card and system memory, but Llama 4 Scout generates painfully slowly that way — the nearest miss we calculate is short by 23.4 GB. Nothing on this page assumes offloading.

Would two GPUs run Llama 4 Scout faster?

Two cards buy memory rather than speed. That matters for Llama 4 Scout only if one card cannot hold it — 43 can, so a second adds little.

Why does the quantisation differ between cards for Llama 4 Scout?

A larger card holds a more accurate copy. Across the cards that run Llama 4 Scout, 6 compression levels are used; the floor control above pins it to one.

How accurate are these Llama 4 Scout speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 19–50 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

What GPU do I need to run Llama 4 Scout?

The smallest card in our catalogue that holds Llama 4 Scout is the Radeon Instinct MI200, with 64 GB of memory. It runs the model at Q3_K_M using about 54.0 GB, and produces roughly 13.4 tokens per second. 43 cards in total can run it.

How fast is Llama 4 Scout on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 31.1 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 39 of the cards that can run Llama 4 Scout clear that.
