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 OpenLLaMA-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 OpenLLaMA-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

What it takes to run this model

Minimum card

P102-101

Memory needed

8.6 GB

Fastest

261 tok/s

OpenLLaMA-13B is small enough at 13B parameters that hardware is rarely the obstacle — 306 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the P102-101 with 10 GB, running it at IQ4_XS and producing around 21.8 tokens per second.

The quickest result comes from a B200 at around 261 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Background

OpenLLaMA-13B was published by OpenLM Research, in United States of America, in May 2023. It comes out of research collective.

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

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.

Reading the throughput figures

Across every card that can run it, the middle of the range is about 24.3 tokens per second, and 269 of them clear the ten tokens per second that roughly matches reading speed.

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

Its attention layout is on file, so the memory figures are computed exactly rather than approximated.

Training and provenance

Producing it required around 7.8 × 10²² FLOP of arithmetic, on Google TPU v4, which is a statement about the training budget rather than about inference.

The training set ran to roughly 1,000,000,000,000 tokens.

Step by step

How to choose a GPU for OpenLLaMA-13B

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 OpenLLaMA-13B — around 8.6 GB at IQ4_XS. Capacity is the gate — a card either holds it or it does not.
02

Decide how long your conversations run

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context OpenLLaMA-13B can slip off a card that handles short questions easily.
03

Choose how far you will compress it

Each card runs the least-compressed copy it can hold — IQ4_XS on the smallest card that fits. Setting a floor drops the cards that only manage OpenLLaMA-13B by squeezing it further than you would want.
04

Rank by throughput rather than spec sheet

The speed ordering for OpenLLaMA-13B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 261 tok/s.
05

Check the fit verdict before buying

Tight means OpenLLaMA-13B loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.
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 OpenLLaMA-13B alone — a card is usually bought for more than one model.

Answers

OpenLLaMA-13B — common questions

Would two GPUs run OpenLLaMA-13B faster?

Two cards buy memory rather than speed. That matters for OpenLLaMA-13B only if one card cannot hold it — 306 can, so a second adds little.

Why does the quantisation differ between cards for OpenLLaMA-13B?

Each card is shown running the least-compressed copy it can hold, and OpenLLaMA-13B appears at 4 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these OpenLLaMA-13B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 222–313 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.

What GPU do I need to run OpenLLaMA-13B?

The smallest card in our catalogue that holds OpenLLaMA-13B is the P102-101, with 10 GB of memory. It runs the model at IQ4_XS using about 8.6 GB, and produces roughly 21.8 tokens per second. 306 cards in total can run it.

How fast is OpenLLaMA-13B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 261 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 269 of the cards that can run OpenLLaMA-13B clear that.

How much VRAM does OpenLLaMA-13B need?

About 8.6 GB at IQ4_XS 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.

Can I run OpenLLaMA-13B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q4_K_M, using about 9.3 GB and generating roughly 68.6 tokens per second — a tight fit.

Can I run OpenLLaMA-13B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 12.3 GB and generating roughly 53.5 tokens per second — a tight fit.

Can I run OpenLLaMA-13B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 15.4 GB and generating roughly 43.7 tokens per second — a comfortable fit.

Is OpenLLaMA-13B open source?

Its weights are published, so OpenLLaMA-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.

How many parameters does OpenLLaMA-13B have?

OpenLLaMA-13B has 13B parameters. 13B. 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.

Who created OpenLLaMA-13B?

OpenLLaMA-13B was published by OpenLM Research, based in United States of America, categorised as research collective.

When was OpenLLaMA-13B released?

OpenLLaMA-13B was published in May 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.

What is OpenLLaMA-13B used for?

OpenLLaMA-13B works in Language, and is recorded as handling language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download OpenLLaMA-13B?

The weights for OpenLLaMA-13B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

How much compute was used to train OpenLLaMA-13B?

Around 7.8 × 10²² 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.

Can I run OpenLLaMA-13B if it does not fit in my GPU?

It can be split between the card and system memory, but OpenLLaMA-13B generates painfully slowly that way — the nearest miss we calculate is short by 2.1 GB. Nothing on this page assumes offloading.
