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.

Stable Beluga 1 sits at 65.2B parameters, which puts it above consumer hardware and into the range where a card is bought for this purpose rather than repurposed for it. 61 of the cards we track can hold it.

At the low end, a A100 PCIe 40 GB handles it — 40 GB, at Q3_K_M, for about 27.3 tokens per second.

Top of the range is the B200, at roughly 52.0 tokens per second thanks to 8,000 GB/s of bandwidth.

About this model

Stable Beluga 1 was published by Stability AI, in United Kingdom of Great Britain and Northern Ireland, in July 2023. industry is the category the publisher falls under.

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

It is derived from LLaMA-65B rather than trained from scratch, which is the usual way a specialised model is produced.

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.

How fast it runs, and why

Across every card that can run it, the middle of the range is about 13.3 tokens per second, and 56 of them clear the ten tokens per second that roughly matches reading speed.

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.

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 Stable Beluga 1

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

    The table lists every card that can hold Stable Beluga 1 — around 32.6 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.

  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 Stable Beluga 1 can slip off a card that handles short questions easily.

  3. 03

    Decide how much compression you will accept

    Each card runs the least-compressed copy it can hold — Q3_K_M on the smallest card that fits. Setting a floor drops the cards that only manage Stable Beluga 1 by squeezing it further than you would want.

  4. 04

    Compare tokens per second, not specifications

    Sort by speed to see how cards rank for Stable Beluga 1. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 52.0 tok/s.

  5. 05

    Check the fit verdict before buying

    A tight fit runs Stable Beluga 1 but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.

  6. 06

    Check the card from the other side

    Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Stable Beluga 1.

Answers

Stable Beluga 1 — common questions

01

How fast is Stable Beluga 1 on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 52.0 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 56 of the cards that can run Stable Beluga 1 clear that.

02

How much VRAM does Stable Beluga 1 need?

About 32.6 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.

03

Is Stable Beluga 1 open source?

Its weights are published, so Stable Beluga 1 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.

04

How many parameters does Stable Beluga 1 have?

Stable Beluga 1 has 65.2B parameters. 65.2B. 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.

05

Who created Stable Beluga 1?

Stable Beluga 1 was published by Stability AI, based in United Kingdom of Great Britain and Northern Ireland, categorised as industry.

06

When was Stable Beluga 1 released?

Stable Beluga 1 was published in July 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.

07

What is Stable Beluga 1 used for?

Stable Beluga 1 works in Language, and is recorded as handling language 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.

08

Where can I download Stable Beluga 1?

The weights for Stable Beluga 1 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

09

Can I run Stable Beluga 1 if it does not fit in my GPU?

It can be split between the card and system memory, but Stable Beluga 1 generates painfully slowly that way — the nearest miss we calculate is short by 11.3 GB. Nothing on this page assumes offloading.

10

Would two GPUs run Stable Beluga 1 faster?

Two cards buy memory rather than speed. That matters for Stable Beluga 1 only if one card cannot hold it — 61 can, so a second adds little.

11

Why does the quantisation differ between cards for Stable Beluga 1?

A larger card holds a more accurate copy. Across the cards that run Stable Beluga 1, 4 compression levels are used; the floor control above pins it to one.

12

How accurate are these Stable Beluga 1 speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 31–83 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.

13

What GPU do I need to run Stable Beluga 1?

The smallest card in our catalogue that holds Stable Beluga 1 is the A100 PCIe 40 GB, with 40 GB of memory. It runs the model at Q3_K_M using about 32.6 GB, and produces roughly 27.3 tokens per second. 61 cards in total can run it.
