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 OLMo 2 32B

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 OLMo 2 32B

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

RTX A4500

Memory needed

16.3 GB

Fastest

106 tok/s

With 32B parameters, OLMo 2 32B lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.

The smallest card that holds it is the RTX A4500 with 20 GB, running it at Q3_K_M and producing around 22.9 tokens per second.

A B200 is the fastest we calculate for it: about 106 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

OLMo 2 32B was published by Allen Institute for AI, in United States of America, in March 2025. research collective is the category the publisher falls under.

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

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded. It is published under the allenai organisation on Hugging Face.

How fast it runs, and why

Across every card that can run it, the middle of the range is about 20.7 tokens per second, and 103 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 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.

What went into building it

Producing it required around 1.3 × 10²⁴ FLOP of arithmetic, on NVIDIA H100 SXM5 80GB, which is a statement about the training budget rather than about inference.

The training set ran to roughly 4,000,000,000,000 tokens.

Step by step

How to choose a GPU for OLMo 2 32B

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

01

Start from the memory column

The table lists every card that can hold OLMo 2 32B — around 16.3 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Decide how long your conversations run

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason OLMo 2 32B stops fitting a card that seemed fine.
03

Choose how far you will compress it

The quantisation column varies by card, because a bigger card holds a more accurate copy of OLMo 2 32B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.
04

Rank by throughput rather than spec sheet

The speed ordering for OLMo 2 32B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 106 tok/s.
05

Check the fit verdict before buying

Tight means OLMo 2 32B 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

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for OLMo 2 32B alone — a card is usually bought for more than one model.

Answers

OLMo 2 32B — common questions

Can I run OLMo 2 32B 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 5.7 GB. Our figures for OLMo 2 32B assume it is fully resident.

Would two GPUs run OLMo 2 32B faster?

Two cards buy memory rather than speed. That matters for OLMo 2 32B only if one card cannot hold it — 132 can, so a second adds little.

Why does the quantisation differ between cards for OLMo 2 32B?

Each card is shown running the least-compressed copy it can hold, and OLMo 2 32B appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these OLMo 2 32B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 64–169 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 OLMo 2 32B?

The smallest card in our catalogue that holds OLMo 2 32B is the RTX A4500, with 20 GB of memory. It runs the model at Q3_K_M using about 16.3 GB, and produces roughly 22.9 tokens per second. 132 cards in total can run it.

How fast is OLMo 2 32B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 106 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 103 of the cards that can run OLMo 2 32B clear that.

How much VRAM does OLMo 2 32B need?

About 16.3 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.

Can I run OLMo 2 32B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 20.1 GB and generating roughly 40.9 tokens per second — a tight fit.

Is OLMo 2 32B open source?

Its weights are published, so OLMo 2 32B 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 OLMo 2 32B have?

OLMo 2 32B has 32B parameters. 32B. 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 OLMo 2 32B?

OLMo 2 32B was published by Allen Institute for AI, based in United States of America, categorised as research collective.

When was OLMo 2 32B released?

OLMo 2 32B was published in March 2025.

What is OLMo 2 32B used for?

OLMo 2 32B 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 OLMo 2 32B?

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

How much compute was used to train OLMo 2 32B?

Around 1.3 × 10²⁴ FLOP, on NVIDIA H100 SXM5 80GB. 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.
