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 StableLM-Base-Alpha-7B

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 StableLM-Base-Alpha-7B

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 you need to run it

Minimum card

Tesla K20c

Memory needed

4.5 GB

Fastest

492 tok/s

StableLM-Base-Alpha-7B is small enough at 6.9B parameters that hardware is rarely the obstacle — 589 of the cards we track can run it, including cards several years old.

The least hardware that works is a Tesla K20c. Its 5 GB is enough at IQ4_XS compression, giving roughly 26.7 tokens per second.

The quickest result comes from a B200 at around 492 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

About this model

StableLM-Base-Alpha-7B was published by Stability AI, in United Kingdom of Great Britain and Northern Ireland, in August 2023. It comes out of industry.

It works in Language, and is recorded as doing language modeling.

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

How fast it runs, and why

The median result is around 26.6 tokens per second; 562 cards produce text faster than most people read it.

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.

Training and provenance

Training it took roughly 4.5 × 10²² FLOP of computation, on NVIDIA A100 SXM4 40 GB — a measure of what producing the model cost, not of how fast it answers.

The training set ran to roughly 1,100,000,000,000 tokens.

Step by step

How to choose a GPU for StableLM-Base-Alpha-7B

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

Look at what StableLM-Base-Alpha-7B actually needs — around 4.5 GB at IQ4_XS. No amount of processing power compensates for a card that cannot hold it.
02

Match the context to your actual use

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context StableLM-Base-Alpha-7B can slip off a card that handles short questions easily.
03

Decide how much compression you will accept

Compression is what makes StableLM-Base-Alpha-7B fit smaller cards, at some cost in accuracy — IQ4_XS on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Sort by speed

Sort by speed to see how cards rank for StableLM-Base-Alpha-7B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 492 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage StableLM-Base-Alpha-7B from those with room to spare. Buy for the second if the context might grow.
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 StableLM-Base-Alpha-7B is settled.

Answers

StableLM-Base-Alpha-7B — common questions

Why does the quantisation differ between cards for StableLM-Base-Alpha-7B?

Each card is shown running the least-compressed copy it can hold, and StableLM-Base-Alpha-7B appears at 4 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these StableLM-Base-Alpha-7B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 295–787 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 StableLM-Base-Alpha-7B?

The smallest card in our catalogue that holds StableLM-Base-Alpha-7B is the Tesla K20c, with 5 GB of memory. It runs the model at IQ4_XS using about 4.5 GB, and produces roughly 26.7 tokens per second. 589 cards in total can run it.

How fast is StableLM-Base-Alpha-7B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 492 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 562 of the cards that can run StableLM-Base-Alpha-7B clear that.

How much VRAM does StableLM-Base-Alpha-7B need?

About 4.5 GB at IQ4_XS 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 StableLM-Base-Alpha-7B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q6_K, using about 6.5 GB and generating roughly 133 tokens per second — a tight fit.

Can I run StableLM-Base-Alpha-7B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 8.1 GB and generating roughly 56.1 tokens per second — a comfortable fit.

Can I run StableLM-Base-Alpha-7B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 8.1 GB and generating roughly 69.5 tokens per second — a comfortable fit.

Can I run StableLM-Base-Alpha-7B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 8.1 GB and generating roughly 82.4 tokens per second — a comfortable fit.

Is StableLM-Base-Alpha-7B open source?

Its weights are published, so StableLM-Base-Alpha-7B 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 StableLM-Base-Alpha-7B have?

StableLM-Base-Alpha-7B has 6.9B parameters. 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 StableLM-Base-Alpha-7B?

StableLM-Base-Alpha-7B was published by Stability AI, based in United Kingdom of Great Britain and Northern Ireland, categorised as industry.

When was StableLM-Base-Alpha-7B released?

StableLM-Base-Alpha-7B was published in August 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.

What is StableLM-Base-Alpha-7B used for?

StableLM-Base-Alpha-7B works in Language, and is recorded as handling language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download StableLM-Base-Alpha-7B?

Its weights are published under the stabilityai 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 StableLM-Base-Alpha-7B?

Around 4.5 × 10²² FLOP, on NVIDIA A100 SXM4 40 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.

Can I run StableLM-Base-Alpha-7B 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 StableLM-Base-Alpha-7B is rarely worth using — the nearest miss we calculate is short by 1.3 GB. Every figure here assumes the whole model is on the card.

Would two GPUs run StableLM-Base-Alpha-7B faster?

A second card roughly doubles the memory available but not the generation rate. With 589 cards already able to run StableLM-Base-Alpha-7B alone, the case for pairing is weak.
