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.

Smaug-72B reaches a parameter count of 72B. 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: 61.
At the low end it is handled by A100 PCIe 40 GB, with a memory capacity of 40 GB, running it at a compression of Q3_K_M and producing around 24.8 tokens per second.
The quickest result comes from B200, generating roughly 47.1 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.
About this model
Smaug-72B was published by Abacus AI, in the country recorded as United States of America, during July 2024. It comes out of an organisation categorised as industry.
It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering.
Its starting point was an existing base model, Qwen-72B. That is the usual way a specialised model is produced.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold. On Hugging Face it is published under the organisation abacusai.
How fast it runs, and why
Across every card that can run it, the middle of the range sits at 16.6 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 51 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.
Step by step
How to choose a GPU for Smaug-72B
The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.
-
01
Check what it needs before anything else
Start from what it actually needs, which is the requirement of Smaug-72B, needing around 35.9 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
-
02
Set the context length you will work at
The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect, because at long context a card that handles short questions easily can be dropped by Smaug-72B.
-
03
Set a quality floor
Each card runs the least-compressed copy it can hold, 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
Sort by speed
The speed ordering is effectively an ordering by memory bandwidth, for Smaug-72B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 47.1 tok/s.
-
05
Read the fit column last
The fit column separates cards that just manage it from those with room to spare, in the case of Smaug-72B. 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
Check the card from the other side
Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond Smaug-72B.
Answers
Smaug-72B — common questions
Smaug-72B— how fast is it on a GPU?
It depends on the card. The quickest we calculate is B200, at about 47.1 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: 51.
Smaug-72B— how much VRAM does it need?
It needs about 35.9 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.
Smaug-72B— 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.
Smaug-72B— how many parameters does it have?
It has a parameter count of 72B. For 72B, we start from MoMo-72b-lora-1.8.7-DPO [Moreh, 2024], which itself is a fine-tune of Qwen72B [Bai et al., 2023]. MoMo-72b-lora-1.8.7-DPO has already undergone SFT, so we simply run the DPOP routines as in Smaug-34B. 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.
Smaug-72B— who created it?
It was published by Abacus AI, based in United States of America, an organisation categorised as industry.
Smaug-72B— when was it released?
It was published in July 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
Smaug-72B— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
Smaug-72B— where can I download it?
Its weights are published on Hugging Face, under the organisation abacusai. We do not host model files — this site calculates what hardware is needed to run them.
Smaug-72B— can I run it if it does not fit in my GPU?
Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. The nearest miss we calculate falls short by 15.5 GB. Every figure here assumes the whole model is resident on the card.
Smaug-72B— would two GPUs run it faster?
A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 61. So a second card is rarely the answer here.
Smaug-72B— 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: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.
Smaug-72B— how accurate are these speed estimates?
They are calculated from specifications rather than measured, and each carries a range. One example: 28–75 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.
Smaug-72B— what GPU do I need to run it?
The smallest card in our catalogue that holds it is A100 PCIe 40 GB, with a memory capacity of 40 GB. It runs the model at a compression of Q3_K_M using about 35.9 GB, and produces roughly 24.8 tokens per second. The number of cards able to run it in total: 61.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
