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.

1,783 tok/s

Ankh_large is small enough at 1.9B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The least hardware that works is a Tesla C1080. Its 4 GB is enough at Q8_0 compression, giving roughly 19.4 tokens per second.

Top of the range is the B200, at roughly 1,783 tokens per second thanks to 8,000 GB/s of bandwidth.

About this model

Ankh_large was published by Technical University of Munich,Columbia University, in Germany, in January 2023. The organisation is categorised as academia,Academia.

It works in Biology, and is recorded as doing protein generation, Proteins, Protein or nucleotide language model (pLM/nLM), Protein contact and distance prediction, Protein classification, Protein localization prediction, Protein fold classification.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. It is published under the ElnaggarLab organisation on Hugging Face.

How fast it runs, and why

Half the cards that hold it manage more than 50.1 tokens per second, and 789 exceed reading speed outright.

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

The training run consumed about 6.5 × 10²¹ FLOP, on Google TPU v4. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

It was trained on about 14,000,000,000 tokens of text.

The reason it appears in this catalogue at all is sOTA improvement.

Step by step

How to choose a GPU for Ankh_large

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

  1. 01

    Start from the memory column

    The table lists every card that can hold Ankh_large — around 2.7 GB at Q8_0. That figure, not the card's headline performance, is what decides whether it runs.

  2. 02

    Set the context length you will work at

    Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Ankh_large stops fitting a card that seemed fine.

  3. 03

    Choose how far you will compress it

    The quantisation column varies by card, because a bigger card holds a more accurate copy of Ankh_large — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Sort by speed

    The speed ordering for Ankh_large is effectively an ordering by memory bandwidth, which is why the B200 tops it at 1,783 tok/s.

  5. 05

    Check the fit verdict before buying

    A tight fit runs Ankh_large but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.

  6. 06

    Check the card from the other side

    Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Ankh_large.

Answers

Ankh_large — common questions

01

Can I run Ankh_large on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 2.7 GB and generating roughly 299 tokens per second — a comfortable fit.

02

Is Ankh_large open source?

Its weights are published, so Ankh_large 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.

03

How many parameters does Ankh_large have?

Ankh_large has 1.9B parameters. Figure 1 indicates 1.15B parameters, but both the huggingface model and a replication (https://huggingface.co/ElnaggarLab/ankh-large and https://www.biorxiv.org/content/10.1101/2023.07.05.547496v1.full.pdf) indicate 1.9B parameters. Notebook for counting params: https://colab.research.google.com/drive/1EGI5_vDl4pOBUukJexMHQR16BFKJe4a5?usp=sharing. 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.

04

Who created Ankh_large?

Ankh_large was published by Technical University of Munich,Columbia University, based in Germany, categorised as academia,Academia.

05

When was Ankh_large released?

Ankh_large was published in January 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

06

What is Ankh_large used for?

Ankh_large works in Biology, and is recorded as handling protein generation, Proteins, Protein or nucleotide language model (pLM/nLM), Protein contact and distance prediction, Protein classification, Protein localization prediction, Protein fold classification. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

07

Where can I download Ankh_large?

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

08

How much compute was used to train Ankh_large?

Around 6.5 × 10²¹ FLOP, on Google TPU v4. 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.

09

Can I run Ankh_large 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 Ankh_large is rarely worth using. Every figure here assumes the whole model is on the card.

10

Would two GPUs run Ankh_large faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run Ankh_large alone, the case for pairing is weak.

11

Why does the quantisation differ between cards for Ankh_large?

Each card is shown running the least-compressed copy it can hold, and Ankh_large appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

12

How accurate are these Ankh_large speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 1,070–2,853 tok/s on the B200 rather than a single number.

13

What GPU do I need to run Ankh_large?

The smallest card in our catalogue that holds Ankh_large is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 2.7 GB, and produces roughly 19.4 tokens per second. 818 cards in total can run it.

14

How fast is Ankh_large on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 1,783 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 789 of the cards that can run Ankh_large clear that.

15

How much VRAM does Ankh_large need?

About 2.7 GB at Q8_0 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.

16

Can I run Ankh_large on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 2.7 GB and generating roughly 332 tokens per second — a comfortable fit.

17

Can I run Ankh_large on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 2.7 GB and generating roughly 203 tokens per second — a comfortable fit.

18

Can I run Ankh_large on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 2.7 GB and generating roughly 252 tokens per second — a comfortable fit.
