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.

The extremes

The ten fastest GPUs that run 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 reaches a parameter count of 109B. That puts it above consumer hardware, into the range where a card is bought for this purpose rather than repurposed for it. The number of cards we track that can hold it: 43.

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

The fastest we calculate for it is B200, generating roughly 31.1 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

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

It works in the domain of Multimodal, Language, Vision, and is recorded as performing the task of 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. On Hugging Face it is published under the organisation meta-llama.

How fast it runs, and why

Half the cards that hold it manage more than 18.2 tokens per second. Exceeding reading speed outright: 39 of them.

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 measures what producing the model cost, and has no bearing on how fast it answers.

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

The reason it appears in this catalogue at all: 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 able to hold Llama 4 Scout, needing around 54.0 GB at a compression of Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
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 a model fit smaller cards, at some cost in accuracy, reaching a compression of Q3_K_M on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Rank by throughput rather than spec sheet

The speed ordering is effectively an ordering by memory bandwidth, for Llama 4 Scout. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 31.1 tok/s.
05

Check the fit verdict before buying

Tight means it loads and works with no room to raise the context later, in the case of Llama 4 Scout. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
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. A card is usually bought for more than one model, so it is worth a look before buying for Llama 4 Scout.

Answers

Llama 4 Scout — common questions

Llama 4 Scout— how much VRAM does it need?

It needs about 54.0 GB at a compression of Q3_K_M, 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.

Llama 4 Scout— is it open source?

Its weights are published, so it 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.

Llama 4 Scout— how many parameters does it have?

It has a parameter count of 109B. "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.

Llama 4 Scout— who created it?

It was published by Meta AI, based in United States of America, an organisation categorised as industry.

Llama 4 Scout— when was it released?

It was published in April 2025.

Llama 4 Scout— what is it used for?

It works in the domain of Multimodal, Language, Vision, and is recorded as handling the task of 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.

Llama 4 Scout— where can I download it?

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

Llama 4 Scout— how much compute was used to train it?

Training consumed 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.

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

It can be split between the card and system memory, but it generates painfully slowly that way. The nearest miss we calculate falls short by 23.4 GB. Every figure here assumes the whole model is resident on the card.

Llama 4 Scout— would two GPUs run it faster?

Two cards buy memory rather than speed, which matters only if one card cannot hold it. The number that can: 43. So a second card is rarely the answer here.

Llama 4 Scout— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 6. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Llama 4 Scout— how accurate are these speed estimates?

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

Llama 4 Scout— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Radeon Instinct MI200, with a memory capacity of 64 GB. It runs the model at a compression of Q3_K_M using about 54.0 GB, and produces roughly 13.4 tokens per second. The number of cards able to run it in total: 43.

Llama 4 Scout— how fast is it on a GPU?

It depends on the card. The quickest we calculate is 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 the number of cards clearing that: 39.
