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 Skywork-OR1-32B

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 Skywork-OR1-32B

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, Skywork-OR1-32B 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.

Background

Skywork-OR1-32B was published by Kunlun Inc., in China, in May 2025. industry is the category the publisher falls under.

It works in Language, and is recorded as doing code generation, Language modeling/generation.

It builds on DeepSeek-R1-Distill-Qwen-32B, which is why it shares that model's general shape and size.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.

Reading the throughput figures

Half the cards that hold it manage more than 20.7 tokens per second, and 103 exceed reading speed outright.

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.

Step by step

How to choose a GPU for Skywork-OR1-32B

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

The table lists every card that can hold Skywork-OR1-32B — around 16.3 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
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 Skywork-OR1-32B stops fitting a card that seemed fine.
03

Decide how much compression you will accept

Each card runs the least-compressed copy it can hold — Q3_K_M on the smallest card that fits. Setting a floor drops the cards that only manage Skywork-OR1-32B by squeezing it further than you would want.
04

Sort by speed

Ranking by tokens per second for Skywork-OR1-32B follows memory bandwidth, not core counts, which is why the B200 tops it at 106 tok/s.
05

Read the fit column last

Tight means Skywork-OR1-32B 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

Check the card from the other side

Following a card through to its own page shows every other model it can hold, which is the question that follows once Skywork-OR1-32B is settled.

Answers

Skywork-OR1-32B — common questions

What GPU do I need to run Skywork-OR1-32B?

The smallest card in our catalogue that holds Skywork-OR1-32B 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 Skywork-OR1-32B 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 Skywork-OR1-32B clear that.

How much VRAM does Skywork-OR1-32B 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 Skywork-OR1-32B 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 Skywork-OR1-32B open source?

Its weights are published, so Skywork-OR1-32B 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 Skywork-OR1-32B have?

Skywork-OR1-32B 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 Skywork-OR1-32B?

Skywork-OR1-32B was published by Kunlun Inc., based in China, categorised as industry.

When was Skywork-OR1-32B released?

Skywork-OR1-32B was published in May 2025.

What is Skywork-OR1-32B used for?

Skywork-OR1-32B works in Language, and is recorded as handling code generation, Language modeling/generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Skywork-OR1-32B?

The weights for Skywork-OR1-32B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

Can I run Skywork-OR1-32B if it does not fit in my GPU?

It can be split between the card and system memory, but Skywork-OR1-32B generates painfully slowly that way — the nearest miss we calculate is short by 5.7 GB. Nothing on this page assumes offloading.

Would two GPUs run Skywork-OR1-32B faster?

Two cards buy memory rather than speed. That matters for Skywork-OR1-32B only if one card cannot hold it — 132 can, so a second adds little.

Why does the quantisation differ between cards for Skywork-OR1-32B?

Each card is shown running the least-compressed copy it can hold, and Skywork-OR1-32B appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Skywork-OR1-32B speed estimates?

These are estimates with real error bars. The fastest result here, 64–169 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.
