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.

With 32B parameters, Kevin-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 entry point is the RTX A4500: 20 GB of memory, Q3_K_M compression, roughly 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.

What this model is

Kevin-32B was published by Cognition,Stanford University, in United States of America, in May 2025. industry,Academia is the category the publisher falls under.

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

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

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. It is published under the cognition-ai organisation on Hugging Face.

What decides the speed

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.

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.

Step by step

How to choose a GPU for Kevin-32B

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

  1. 01

    Read the memory figure first

    Look at what Kevin-32B actually needs — around 16.3 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Set the context length you will work at

    The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Kevin-32B can slip off a card that handles short questions easily.

  3. 03

    Set a quality floor

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

  4. 04

    Rank by throughput rather than spec sheet

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

  5. 05

    Look at the headroom, not just the fit

    The fit column separates cards that just manage Kevin-32B from those with room to spare. Buy for the second if the context might grow.

  6. 06

    Open the card you have settled on

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

Answers

Kevin-32B — common questions

01

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

Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded Kevin-32B is rarely worth using — the nearest miss we calculate is short by 5.7 GB. Every figure here assumes the whole model is on the card.

02

Would two GPUs run Kevin-32B faster?

Capacity adds across cards; throughput does not. Since 132 of the cards we track already hold Kevin-32B on their own, a second card is rarely the answer here.

03

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

A larger card holds a more accurate copy. Across the cards that run Kevin-32B, 5 compression levels are used; the floor control above pins it to one.

04

How accurate are these Kevin-32B speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 64–169 tok/s on the B200 rather than a single number.

05

What GPU do I need to run Kevin-32B?

The smallest card in our catalogue that holds Kevin-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.

06

How fast is Kevin-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 Kevin-32B clear that.

07

How much VRAM does Kevin-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.

08

Can I run Kevin-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.

09

Is Kevin-32B open source?

Its weights are published, so Kevin-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.

10

How many parameters does Kevin-32B have?

Kevin-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.

11

Who created Kevin-32B?

Kevin-32B was published by Cognition,Stanford University, based in United States of America, categorised as industry,Academia.

12

When was Kevin-32B released?

Kevin-32B was published in May 2025.

13

What is Kevin-32B used for?

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

14

Where can I download Kevin-32B?

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