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.

What it takes to run this model

Minimum card

A100 PCIe 40 GB

Memory needed

34.9 GB

Fastest

48.4 tok/s

Apertus 70B reaches a parameter count of 70B. 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.

The smallest card that holds it is A100 PCIe 40 GB, with a memory capacity of 40 GB, running it at a compression of Q3_K_M and producing around 25.5 tokens per second.

The quickest result comes from B200, generating roughly 48.4 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

Apertus 70B was published by ETH Zurich,Ecole Polytechnique F´ed´erale de Lausanne (EPFL),Swiss National Supercomputing Centre (CSCS),Swisscom, in the country recorded as Switzerland, during September 2025. It comes out of an organisation categorised as academia,Academia,Academia,Industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Code generation, Translation.

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 swiss-ai.

Understanding the speeds

The median result is around 17.1 tokens per second. Producing text faster than most people read it: 50 of them.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Training and provenance

Producing it required arithmetic totalling around 6.7 × 10²⁴ FLOP, on hardware recorded as NVIDIA GH200. That figure measures what producing the model cost, and has no bearing on how fast it answers.

It was trained on a corpus of about 15,000,000,000,000 tokens of text.

Step by step

How to choose a GPU for Apertus 70B

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

  1. 01

    Read the memory figure first

    Start from what it actually needs, which is the requirement of Apertus 70B, needing around 34.9 GB at a compression of Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 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 Apertus 70B.

  3. 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.

  4. 04

    Compare tokens per second, not specifications

    Ranking by tokens per second follows memory bandwidth rather than core counts, for Apertus 70B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 48.4 tok/s.

  5. 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 Apertus 70B. 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.

  6. 06

    Check the card from the other side

    Following a card through to its own page shows every other model it can hold, which is the question that follows once you have settled on Apertus 70B.

Answers

Apertus 70B — common questions

01

Apertus 70B— 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, Code generation, Translation. These are the areas it was designed around; they describe intent rather than a hard boundary.

02

Apertus 70B— where can I download it?

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

03

Apertus 70B— how much compute was used to train it?

Training consumed around 6.7 × 10²⁴ FLOP, on hardware recorded as NVIDIA GH200. 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.

04

Apertus 70B— 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 14.2 GB. Every figure here assumes the whole model is resident on the card.

05

Apertus 70B— 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: 61. So a second card is rarely the answer here.

06

Apertus 70B— why does the quantisation differ between cards?

Because capacity varies, so does how hard it has to be squeezed. The number of distinct levels in the table above: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

07

Apertus 70B— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 29–77 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

08

Apertus 70B— 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 34.9 GB, and produces roughly 25.5 tokens per second. The number of cards able to run it in total: 61.

09

Apertus 70B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 48.4 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: 50.

10

Apertus 70B— how much VRAM does it need?

It needs about 34.9 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.

11

Apertus 70B— 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.

12

Apertus 70B— how many parameters does it have?

It has a parameter count of 70B. 70B. 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.

13

Apertus 70B— who created it?

It was published by ETH Zurich,Ecole Polytechnique F´ed´erale de Lausanne (EPFL),Swiss National Supercomputing Centre (CSCS),Swisscom, based in Switzerland, an organisation categorised as academia,Academia,Academia,Industry.

14

Apertus 70B— when was it released?

It was published in September 2025.
