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.

OpenThaiGPT v1.0.0 (13B) is small enough at 13.1B parameters that hardware is rarely the obstacle — 509 of the cards we track can run it, including cards several years old.

At the low end, a Xeon Phi 5110P handles it — 8 GB, at Q3_K_M, for about 18.2 tokens per second.

A B200 is the fastest we calculate for it: about 259 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

OpenThaiGPT v1.0.0 (13B) was published by Mahidol University,AI Entrepreneurs Association of Thailand, in Thailand, in April 2024. The organisation is categorised as academia.

It works in Language, and is recorded as doing chat, Language modeling/generation, Question answering, Retrieval-augmented generation.

It builds on Llama 2-13B, which is why it shares that model's general shape and size.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all. It is published under the openthaigpt organisation on Hugging Face.

How fast it runs, and why

The median result is around 21.1 tokens per second; 459 cards produce text faster than most people read it.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

Memory here is estimated from size rather than computed from the architecture, which is not recorded for this model — the numbers are indicative rather than exact.

How it was trained

The training run consumed about 5.1 × 10²¹ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Step by step

How to choose a GPU for OpenThaiGPT v1.0.0 (13B)

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

  1. 01

    Check what it needs before anything else

    Every card here has been checked against OpenThaiGPT v1.0.0 (13B) — around 7.1 GB at Q3_K_M. Capacity is the gate — a card either holds it or it does not.

  2. 02

    Match the context to your actual use

    Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason OpenThaiGPT v1.0.0 (13B) stops fitting a card that seemed fine.

  3. 03

    Decide how much compression you will accept

    The quantisation column varies by card, because a bigger card holds a more accurate copy of OpenThaiGPT v1.0.0 (13B) — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Rank by throughput rather than spec sheet

    Sort by speed to see how cards rank for OpenThaiGPT v1.0.0 (13B). It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 259 tok/s.

  5. 05

    Look at the headroom, not just the fit

    The fit column separates cards that just manage OpenThaiGPT v1.0.0 (13B) from those with room to spare. Buy for the second if the context might grow.

  6. 06

    Check the card from the other side

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for OpenThaiGPT v1.0.0 (13B) alone — a card is usually bought for more than one model.

Answers

OpenThaiGPT v1.0.0 (13B) — common questions

01

When was OpenThaiGPT v1.0.0 (13B) released?

OpenThaiGPT v1.0.0 (13B) was published in April 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.

02

What is OpenThaiGPT v1.0.0 (13B) used for?

OpenThaiGPT v1.0.0 (13B) works in Language, and is recorded as handling chat, Language modeling/generation, Question answering, Retrieval-augmented generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

03

Where can I download OpenThaiGPT v1.0.0 (13B)?

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

04

How much compute was used to train OpenThaiGPT v1.0.0 (13B)?

Around 5.1 × 10²¹ 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.

05

Can I run OpenThaiGPT v1.0.0 (13B) if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down — the nearest miss we calculate is short by 3.2 GB. Our figures for OpenThaiGPT v1.0.0 (13B) assume it is fully resident.

06

Would two GPUs run OpenThaiGPT v1.0.0 (13B) faster?

A second card roughly doubles the memory available but not the generation rate. With 509 cards already able to run OpenThaiGPT v1.0.0 (13B) alone, the case for pairing is weak.

07

Why does the quantisation differ between cards for OpenThaiGPT v1.0.0 (13B)?

Because capacity varies, so does how hard OpenThaiGPT v1.0.0 (13B) has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

08

How accurate are these OpenThaiGPT v1.0.0 (13B) speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 155–414 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

09

What GPU do I need to run OpenThaiGPT v1.0.0 (13B)?

The smallest card in our catalogue that holds OpenThaiGPT v1.0.0 (13B) is the Xeon Phi 5110P, with 8 GB of memory. It runs the model at Q3_K_M using about 7.1 GB, and produces roughly 18.2 tokens per second. 509 cards in total can run it.

10

How fast is OpenThaiGPT v1.0.0 (13B) on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 259 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 459 of the cards that can run OpenThaiGPT v1.0.0 (13B) clear that.

11

How much VRAM does OpenThaiGPT v1.0.0 (13B) need?

About 7.1 GB at Q3_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 OpenThaiGPT v1.0.0 (13B) on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q3_K_M, using about 7.1 GB and generating roughly 130 tokens per second — a tight fit.

13

Can I run OpenThaiGPT v1.0.0 (13B) on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 10.1 GB and generating roughly 52.7 tokens per second — a tight fit.

14

Can I run OpenThaiGPT v1.0.0 (13B) on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 11.7 GB and generating roughly 53.1 tokens per second — a comfortable fit.

15

Can I run OpenThaiGPT v1.0.0 (13B) on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 14.7 GB and generating roughly 43.3 tokens per second — a comfortable fit.

16

Is OpenThaiGPT v1.0.0 (13B) open source?

Its weights are published, so OpenThaiGPT v1.0.0 (13B) 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 OpenThaiGPT v1.0.0 (13B) have?

OpenThaiGPT v1.0.0 (13B) has 13.1B parameters. https://huggingface.co/openthaigpt/openthaigpt-1.0.0-13b-chat. 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.

18

Who created OpenThaiGPT v1.0.0 (13B)?

OpenThaiGPT v1.0.0 (13B) was published by Mahidol University,AI Entrepreneurs Association of Thailand, based in Thailand, categorised as academia.
