The extremes

The ten fastest GPUs that run Hyena-2 153M

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 Hyena-2 153M

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

Tesla C1080

Memory needed

0.9 GB

Fastest

22,145 tok/s

Hyena-2 153M reaches a parameter count of 153M. 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: 818.

The smallest card that holds it is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 241 tokens per second.

The fastest we calculate for it is B200, generating roughly 22,145 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

Hyena-2 153M was published by Stanford University,University of Montreal / Université de Montréal,Mila - Quebec AI (originally Montreal Institute for Learning Algorithms), in the country recorded as United States of America, during February 2023. It comes out of an organisation categorised as academia,Academia,Academia.

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

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.

Understanding the speeds

The median result is around 621.8 tokens per second. Exceeding reading speed outright: 818 of them.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

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.

How it was trained

Producing it required arithmetic totalling around 1.9 × 10¹⁹ FLOP, on hardware recorded as NVIDIA A100 SXM4 80 GB. That figure measures what producing the model cost, and has no bearing on how fast it answers.

The training set ran to roughly 15,000,000,000 tokens of text.

Step by step

How to choose a GPU for Hyena-2 153M

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 able to hold Hyena-2 153M, needing around 0.9 GB at a compression of Q8_0. No amount of processing power compensates for a card that cannot hold it.
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, because at long context a card that handles short questions easily can be dropped by Hyena-2 153M.
03

Choose how far you will compress it

Each card runs the least-compressed copy it can hold, reaching a compression of Q8_0 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

Compare tokens per second, not specifications

The speed ordering is effectively an ordering by memory bandwidth, for Hyena-2 153M. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 22,145 tok/s.
05

Read the fit column last

The fit column separates cards that just manage it from those with room to spare, in the case of Hyena-2 153M. 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

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 you have settled on Hyena-2 153M.

Answers

Hyena-2 153M — common questions

Hyena-2 153M— 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 0.9 GB and generating roughly 3,709 tokens per second. The fit is comfortable.

Hyena-2 153M— 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.

Hyena-2 153M— how many parameters does it have?

It has a parameter count of 153M. 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.

Hyena-2 153M— who created it?

It was published by Stanford University,University of Montreal / Université de Montréal,Mila - Quebec AI (originally Montreal Institute for Learning Algorithms), based in United States of America, an organisation categorised as academia,Academia,Academia.

Hyena-2 153M— when was it released?

It was published in February 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.

Hyena-2 153M— what is it used for?

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

Hyena-2 153M— 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.

Hyena-2 153M— how much compute was used to train it?

Training consumed around 1.9 × 10¹⁹ FLOP, on hardware recorded as NVIDIA A100 SXM4 80 GB. 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.

Hyena-2 153M— 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. Every figure here assumes the whole model is resident on the card.

Hyena-2 153M— would two GPUs run it faster?

A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 818. So a second card is rarely the answer here.

Hyena-2 153M— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Hyena-2 153M— 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: 13,287–35,433 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Hyena-2 153M— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q8_0 using about 0.9 GB, and produces roughly 241 tokens per second. The number of cards able to run it in total: 818.

Hyena-2 153M— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 22,145 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: 818.

Hyena-2 153M— how much VRAM does it need?

It needs about 0.9 GB at a compression of Q8_0, 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.

Hyena-2 153M— 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 Q8_0, using about 0.9 GB and generating roughly 4,125 tokens per second. The fit is comfortable.

Hyena-2 153M— 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 Q8_0, using about 0.9 GB and generating roughly 2,526 tokens per second. The fit is comfortable.

Hyena-2 153M— 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 Q8_0, using about 0.9 GB and generating roughly 3,128 tokens per second. The fit is comfortable.
