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.

What it takes to run this model

Minimum card

Tesla C1080

Memory needed

3.0 GB

Fastest

1,212 tok/s

Stable Code 3B is small enough at 2.8B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the Tesla C1080 with 4 GB, running it at Q6_K and producing around 19.2 tokens per second.

At the other end, a B200 generates roughly 1,212 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

About this model

Stable Code 3B was published by Stability AI, in United Kingdom of Great Britain and Northern Ireland, in January 2024. The organisation is categorised as industry.

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

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

How fast it runs, and why

Across every card that can run it, the middle of the range is about 38.5 tokens per second, and 784 of them clear the ten tokens per second that roughly matches reading speed.

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.

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.

How it was trained

The training run consumed about 2.1 × 10²² FLOP, on NVIDIA A100 SXM4 40 GB. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Step by step

How to choose a GPU for Stable Code 3B

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

  1. 01

    Start from the memory column

    Every card here has been checked against Stable Code 3B — around 3.0 GB at Q6_K. Capacity is the gate — a card either holds it or it does not.

  2. 02

    Decide how long your conversations run

    Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Stable Code 3B stops fitting a card that seemed fine.

  3. 03

    Decide how much compression you will accept

    Each card runs the least-compressed copy it can hold — Q6_K on the smallest card that fits. Setting a floor drops the cards that only manage Stable Code 3B by squeezing it further than you would want.

  4. 04

    Rank by throughput rather than spec sheet

    Sort by speed to see how cards rank for Stable Code 3B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 1,212 tok/s.

  5. 05

    Check the fit verdict before buying

    The fit column separates cards that just manage Stable Code 3B from those with room to spare. Buy for the second if the context might grow.

  6. 06

    Check the card from the other side

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for Stable Code 3B alone — a card is usually bought for more than one model.

Answers

Stable Code 3B — common questions

01

Where can I download Stable Code 3B?

The weights for Stable Code 3B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

02

How much compute was used to train Stable Code 3B?

Around 2.1 × 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.

03

Can I run Stable Code 3B if it does not fit in my GPU?

It can be split between the card and system memory, but Stable Code 3B generates painfully slowly that way. Nothing on this page assumes offloading.

04

Would two GPUs run Stable Code 3B faster?

Capacity adds across cards; throughput does not. Since 818 of the cards we track already hold Stable Code 3B on their own, a second card is rarely the answer here.

05

Why does the quantisation differ between cards for Stable Code 3B?

Because capacity varies, so does how hard Stable Code 3B has to be squeezed — 2 distinct levels appear in the table above. Set a minimum quality to compare at one.

06

How accurate are these Stable Code 3B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 727–1,939 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.

07

What GPU do I need to run Stable Code 3B?

The smallest card in our catalogue that holds Stable Code 3B is the Tesla C1080, with 4 GB of memory. It runs the model at Q6_K using about 3.0 GB, and produces roughly 19.2 tokens per second. 818 cards in total can run it.

08

How fast is Stable Code 3B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 1,212 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 784 of the cards that can run Stable Code 3B clear that.

09

How much VRAM does Stable Code 3B need?

About 3.0 GB at Q6_K 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.

10

Can I run Stable Code 3B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 3.7 GB and generating roughly 226 tokens per second — a comfortable fit.

11

Can I run Stable Code 3B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 3.7 GB and generating roughly 138 tokens per second — a comfortable fit.

12

Can I run Stable Code 3B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 3.7 GB and generating roughly 171 tokens per second — a comfortable fit.

13

Can I run Stable Code 3B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 3.7 GB and generating roughly 203 tokens per second — a comfortable fit.

14

Is Stable Code 3B open source?

Its weights are published, so Stable Code 3B 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.

15

How many parameters does Stable Code 3B have?

Stable Code 3B has 2.8B parameters. 2796431360 from https://huggingface.co/stabilityai/stable-code-3b#model-architecture "stable-code-3b is a 2.7B billion parameter decoder-only language model pre-trained on 1.3 trillion tokens of diverse textual and code datasets. ". 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.

16

Who created Stable Code 3B?

Stable Code 3B was published by Stability AI, based in United Kingdom of Great Britain and Northern Ireland, categorised as industry.

17

When was Stable Code 3B released?

Stable Code 3B was published in January 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

18

What is Stable Code 3B used for?

Stable Code 3B works in Language, and is recorded as handling language modeling/generation, Code generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
