The extremes

The ten fastest GPUs that run OpenThaiGPT v1.0.0 (13B)

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run OpenThaiGPT v1.0.0 (13B)

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

Memory needed

7.1 GB

Fastest

259 tok/s

OpenThaiGPT v1.0.0 (13B) reaches a parameter count of 13.1B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 509.

At the low end it is handled by Xeon Phi 5110P, with a memory capacity of 8 GB, running it at a compression of Q3_K_M and producing around 18.2 tokens per second.

The fastest we calculate for it is B200, generating roughly 259 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

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

It works in the domain of Language, and is recorded as performing the task of chat, Language modeling/generation, Question answering, Retrieval-augmented generation.

It builds on Llama 2-13B. Most models at this scale are adapted from an existing base rather than built from nothing.

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. On Hugging Face it is published under the organisation openthaigpt.

How fast it runs, and why

The median result is around 21.1 tokens per second. Exceeding reading speed outright: 459 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.

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 measures what producing the model cost, and has no bearing on how fast it answers.

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.

01

Check what it needs before anything else

Every card here has been checked against OpenThaiGPT v1.0.0 (13B), needing around 7.1 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
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 a card that seemed fine stops fitting OpenThaiGPT v1.0.0 (13B).
03

Decide how much compression you will accept

The quantisation column varies by card, because a bigger card holds a more accurate copy, 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

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, because generation is bound by memory bandwidth. The card topping the list is B200, at 259 tok/s.
05

Look at the headroom, not just the fit

The fit column separates cards that just manage it from those with room to spare, in the case of OpenThaiGPT v1.0.0 (13B). 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

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

Answers

OpenThaiGPT v1.0.0 (13B) — common questions

OpenThaiGPT v1.0.0 (13B)— when was it released?

It 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.

OpenThaiGPT v1.0.0 (13B)— what is it used for?

It works in the domain of Language, and is recorded as handling the task of 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.

OpenThaiGPT v1.0.0 (13B)— where can I download it?

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

OpenThaiGPT v1.0.0 (13B)— how much compute was used to train it?

Training consumed 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.

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

Only by offloading, which is usually a false economy: the part held in system memory drags the whole thing down. The nearest miss we calculate falls short by 3.2 GB. Every figure here assumes the whole model is resident on the card.

OpenThaiGPT v1.0.0 (13B)— 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: 509. So a second card is rarely the answer here.

OpenThaiGPT v1.0.0 (13B)— 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.

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

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

OpenThaiGPT v1.0.0 (13B)— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Xeon Phi 5110P, with a memory capacity of 8 GB. It runs the model at a compression of Q3_K_M using about 7.1 GB, and produces roughly 18.2 tokens per second. The number of cards able to run it in total: 509.

OpenThaiGPT v1.0.0 (13B)— how fast is it on a GPU?

It depends on the card. The quickest we calculate is 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 the number of cards clearing that: 459.

OpenThaiGPT v1.0.0 (13B)— how much VRAM does it need?

It needs about 7.1 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.

OpenThaiGPT v1.0.0 (13B)— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q3_K_M, using about 7.1 GB and generating roughly 130 tokens per second. The fit is tight.

OpenThaiGPT v1.0.0 (13B)— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q5_K_M, using about 10.1 GB and generating roughly 52.7 tokens per second. The fit is tight.

OpenThaiGPT v1.0.0 (13B)— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q6_K, using about 11.7 GB and generating roughly 53.1 tokens per second. The fit is comfortable.

OpenThaiGPT v1.0.0 (13B)— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q8_0, using about 14.7 GB and generating roughly 43.3 tokens per second. The fit is comfortable.

OpenThaiGPT v1.0.0 (13B)— 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.

OpenThaiGPT v1.0.0 (13B)— how many parameters does it have?

It has a parameter count of 13.1B. 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.

OpenThaiGPT v1.0.0 (13B)— who created it?

It was published by Mahidol University,AI Entrepreneurs Association of Thailand, based in Thailand, an organisation categorised as academia.
