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 ether0

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 ether0

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

Hardware requirements in practice

Minimum card

Xeon Phi 7120P

Memory needed

13.8 GB

Fastest

141 tok/s

ether0 reaches a parameter count of 24B. That lands in the range a serious desktop card can handle once the weights are compressed. The number of cards we track that can run it: 241.

The entry point is Xeon Phi 7120P, with a memory capacity of 16 GB, running it at a compression of IQ4_XS and producing around 9.9 tokens per second.

The quickest result comes from B200, generating roughly 141 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

What this model is

ether0 was published by FutureHouse, in the country recorded as United States of America, during June 2025.

It works in the domain of Materials science, Language, and is recorded as performing the task of language modeling/generation, Molecular property prediction.

Rather than being trained from scratch, it is derived from Mistral Small 3. That is the usual way a specialised model is produced.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. On Hugging Face it is published under the organisation futurehouse.

What decides the speed

Half the cards that hold it manage more than 19.4 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 193 of them.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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 ether0

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 able to hold ether0, needing around 13.8 GB at a compression of IQ4_XS. 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 ether0.
03

Set a quality floor

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of IQ4_XS 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

Sort by speed

Sort by speed to see how cards rank for ether0. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 141 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of ether0. 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

Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond ether0.

Answers

ether0 — common questions

ether0— 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: 85–226 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

ether0— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Xeon Phi 7120P, with a memory capacity of 16 GB. It runs the model at a compression of IQ4_XS using about 13.8 GB, and produces roughly 9.9 tokens per second. The number of cards able to run it in total: 241.

ether0— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 141 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: 193.

ether0— how much VRAM does it need?

It needs about 13.8 GB at a compression of IQ4_XS, 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.

ether0— 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 IQ4_XS, using about 13.8 GB and generating roughly 49.0 tokens per second. The fit is tight.

ether0— 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 Q6_K, using about 20.8 GB and generating roughly 34.4 tokens per second. The fit is tight.

ether0— 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.

ether0— how many parameters does it have?

It has a parameter count of 24B. 24B. 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.

ether0— who created it?

It was published by FutureHouse, based in United States of America.

ether0— when was it released?

It was published in June 2025.

ether0— what is it used for?

It works in the domain of Materials science, Language, and is recorded as handling the task of language modeling/generation, Molecular property prediction. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

ether0— where can I download it?

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

ether0— 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. The nearest miss we calculate falls short by 4.4 GB. Every figure here assumes the whole model is resident on the card.

ether0— would two GPUs run it faster?

Two cards buy memory rather than speed, which matters only if one card cannot hold it. The number that can: 241. So a second card is rarely the answer here.

ether0— 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: 4. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.
