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.

The extremes

The ten fastest GPUs that run Polyglot-Ko-12.8B

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 Polyglot-Ko-12.8B

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

What it takes to run this model

Minimum card

Xeon Phi 5110P

Memory needed

7.0 GB

Fastest

263 tok/s

Polyglot-Ko-12.8B reaches a parameter count of 12.9B. 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.

The smallest card that holds it is Xeon Phi 5110P, with a memory capacity of 8 GB, running it at a compression of Q3_K_M and producing around 18.4 tokens per second.

The fastest we calculate for it is B200, generating roughly 263 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

Polyglot-Ko-12.8B was published by EleutherAI, in the country recorded as United States of America, during June 2023. The category the publisher falls under is research collective.

It works in the domain of Language, and is recorded as performing the task of translation, Language modeling/generation.

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

Understanding the speeds

The median result is around 21.4 tokens per second. Producing text faster than most people read it: 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.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

Training and provenance

Training it took a computation budget of roughly 1.3 × 10²² FLOP, on hardware recorded as NVIDIA A100. 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 95,793,000,000 tokens of text.

Step by step

How to choose a GPU for Polyglot-Ko-12.8B

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

01

Read the memory figure first

Every card here has been checked against Polyglot-Ko-12.8B, needing around 7.0 GB at a compression of Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
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 a card that seemed fine stops fitting Polyglot-Ko-12.8B.
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

Sort by speed

The speed ordering is effectively an ordering by memory bandwidth, for Polyglot-Ko-12.8B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 263 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of Polyglot-Ko-12.8B. 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

Answers

Polyglot-Ko-12.8B — common questions

Polyglot-Ko-12.8B— where can I download it?

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

Polyglot-Ko-12.8B— how much compute was used to train it?

Training consumed around 1.3 × 10²² FLOP, on hardware recorded as NVIDIA A100. 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.

Polyglot-Ko-12.8B— 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 3.1 GB. Every figure here assumes the whole model is resident on the card.

Polyglot-Ko-12.8B— 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: 509. So a second card is rarely the answer here.

Polyglot-Ko-12.8B— 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.

Polyglot-Ko-12.8B— 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: 158–420 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Polyglot-Ko-12.8B— 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 7.0 GB, and produces roughly 18.4 tokens per second. The number of cards able to run it in total: 509.

Polyglot-Ko-12.8B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 263 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.

Polyglot-Ko-12.8B— how much VRAM does it need?

It needs about 7.0 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.

Polyglot-Ko-12.8B— 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 7.0 GB and generating roughly 132 tokens per second. The fit is tight.

Polyglot-Ko-12.8B— 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 10.0 GB and generating roughly 53.5 tokens per second. The fit is tight.

Polyglot-Ko-12.8B— 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 11.5 GB and generating roughly 53.9 tokens per second. The fit is comfortable.

Polyglot-Ko-12.8B— 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 14.5 GB and generating roughly 44.0 tokens per second. The fit is comfortable.

Polyglot-Ko-12.8B— 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.

Polyglot-Ko-12.8B— how many parameters does it have?

It has a parameter count of 12.9B. 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.

Polyglot-Ko-12.8B— who created it?

It was published by EleutherAI, based in United States of America, an organisation categorised as research collective.

Polyglot-Ko-12.8B— when was it released?

It was published in June 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.

Polyglot-Ko-12.8B— what is it used for?

It works in the domain of Language, and is recorded as handling the task of translation, Language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.
