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.

Hardware requirements in practice

Minimum card

Tesla K20c

Memory needed

4.4 GB

Fastest

549 tok/s

KoGPT is small enough at 6.2B parameters that hardware is rarely the obstacle — 589 of the cards we track can run it, including cards several years old.

The entry point is the Tesla K20c: 5 GB of memory, Q4_K_M compression, roughly 28.0 tokens per second.

The quickest result comes from a B200 at around 549 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

What this model is

KoGPT was published by Kakao, in Korea (Republic of), in November 2021. It comes out of industry.

It works in Language, and is recorded as doing language modeling/generation, Chat.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.

What decides the speed

The median result is around 27.4 tokens per second; 565 cards produce text faster than most people read it.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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.

Step by step

How to choose a GPU for KoGPT

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

    Look at what KoGPT actually needs — around 4.4 GB at Q4_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

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

  3. 03

    Decide how much compression you will accept

    Compression is what makes KoGPT fit smaller cards, at some cost in accuracy — Q4_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.

  4. 04

    Sort by speed

    Ranking by tokens per second for KoGPT follows memory bandwidth, not core counts, which is why the B200 tops it at 549 tok/s.

  5. 05

    Read the fit column last

    The fit column separates cards that just manage KoGPT from those with room to spare. Buy for the second if the context might grow.

  6. 06

    See what else that card runs

    Following a card through to its own page shows every other model it can hold, which is the question that follows once KoGPT is settled.

Answers

KoGPT — common questions

01

Who created KoGPT?

KoGPT was published by Kakao, based in Korea (Republic of), categorised as industry.

02

When was KoGPT released?

KoGPT was published in November 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

03

What is KoGPT used for?

KoGPT works in Language, and is recorded as handling language modeling/generation, Chat. These are the areas it was designed around; they describe intent rather than a hard boundary.

04

Where can I download KoGPT?

The weights for KoGPT are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

05

Can I run KoGPT 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 KoGPT is rarely worth using — the nearest miss we calculate is short by 0.8 GB. Every figure here assumes the whole model is on the card.

06

Would two GPUs run KoGPT faster?

Capacity adds across cards; throughput does not. Since 589 of the cards we track already hold KoGPT on their own, a second card is rarely the answer here.

07

Why does the quantisation differ between cards for KoGPT?

Because capacity varies, so does how hard KoGPT has to be squeezed — 4 distinct levels appear in the table above. Set a minimum quality to compare at one.

08

How accurate are these KoGPT 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 330–879 tok/s on the B200 rather than a single number.

09

What GPU do I need to run KoGPT?

The smallest card in our catalogue that holds KoGPT is the Tesla K20c, with 5 GB of memory. It runs the model at Q4_K_M using about 4.4 GB, and produces roughly 28.0 tokens per second. 589 cards in total can run it.

10

How fast is KoGPT on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 549 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 565 of the cards that can run KoGPT clear that.

11

How much VRAM does KoGPT need?

About 4.4 GB at Q4_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.

12

Can I run KoGPT on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q6_K, using about 5.9 GB and generating roughly 149 tokens per second — a comfortable fit.

13

Can I run KoGPT on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 7.3 GB and generating roughly 62.7 tokens per second — a comfortable fit.

14

Can I run KoGPT on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 7.3 GB and generating roughly 77.6 tokens per second — a comfortable fit.

15

Can I run KoGPT on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 7.3 GB and generating roughly 92.0 tokens per second — a comfortable fit.

16

Is KoGPT open source?

Its weights are published, so KoGPT 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.

17

How many parameters does KoGPT have?

KoGPT has 6.2B parameters. from https://huggingface.co/kakaobrain/kogpt possibly has 30B parameters based on this source: (would be a different version) https://post.naver.com/viewer/postView.naver?volumeNo=34605062&memberNo=35753905&vType=VERTICAL. 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.
