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.

Memory needed

Fastest

3,388 tok/s

BLOOM-1B is small enough at 1B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The least hardware that works is a Tesla C1080. Its 4 GB is enough at Q8_0 compression, giving roughly 36.9 tokens per second.

Top of the range is the B200, at roughly 3,388 tokens per second thanks to 8,000 GB/s of bandwidth.

What this model is

BLOOM-1B was published by Hugging Face,BigScience, in United States of America, in July 2022. The organisation is categorised as industry,Research collective.

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

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

What decides the speed

Across every card that can run it, the middle of the range is about 95.1 tokens per second, and 806 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.

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.

How it was trained

The training set ran to roughly 354,000,000,000 tokens.

Step by step

How to choose a GPU for BLOOM-1B

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

  1. 01

    Check what it needs before anything else

    Look at what BLOOM-1B actually needs — around 1.8 GB at Q8_0. No amount of processing power compensates for a card that cannot hold it.

  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 BLOOM-1B stops fitting a card that seemed fine.

  3. 03

    Choose how far you will compress it

    Compression is what makes BLOOM-1B fit smaller cards, at some cost in accuracy — Q8_0 on the smallest card that fits. A minimum quality removes the ones that go too far.

  4. 04

    Compare tokens per second, not specifications

    Ranking by tokens per second for BLOOM-1B follows memory bandwidth, not core counts, which is why the B200 tops it at 3,388 tok/s.

  5. 05

    Check the fit verdict before buying

    Tight means BLOOM-1B loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.

  6. 06

    See what else that card runs

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for BLOOM-1B alone — a card is usually bought for more than one model.

Answers

BLOOM-1B — common questions

01

How fast is BLOOM-1B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 3,388 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 806 of the cards that can run BLOOM-1B clear that.

02

How much VRAM does BLOOM-1B need?

About 1.8 GB at Q8_0 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

Can I run BLOOM-1B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 1.8 GB and generating roughly 631 tokens per second — a comfortable fit.

04

Can I run BLOOM-1B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 1.8 GB and generating roughly 386 tokens per second — a comfortable fit.

05

Can I run BLOOM-1B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 1.8 GB and generating roughly 479 tokens per second — a comfortable fit.

06

Can I run BLOOM-1B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 1.8 GB and generating roughly 568 tokens per second — a comfortable fit.

07

Is BLOOM-1B open source?

Its weights are published, so BLOOM-1B 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.

08

How many parameters does BLOOM-1B have?

BLOOM-1B has 1B 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.

09

Who created BLOOM-1B?

BLOOM-1B was published by Hugging Face,BigScience, based in United States of America, categorised as industry,Research collective.

10

When was BLOOM-1B released?

BLOOM-1B was published in July 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

11

What is BLOOM-1B used for?

BLOOM-1B works in Language, and is recorded as handling language modeling/generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

12

Where can I download BLOOM-1B?

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

13

Can I run BLOOM-1B 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 BLOOM-1B is rarely worth using. Every figure here assumes the whole model is on the card.

14

Would two GPUs run BLOOM-1B faster?

Two cards buy memory rather than speed. That matters for BLOOM-1B only if one card cannot hold it — 818 can, so a second adds little.

15

Why does the quantisation differ between cards for BLOOM-1B?

Because capacity varies, so does how hard BLOOM-1B has to be squeezed — 1 distinct levels appear in the table above. Set a minimum quality to compare at one.

16

How accurate are these BLOOM-1B speed estimates?

These are estimates with real error bars. The fastest result here, 2,033–5,421 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

17

What GPU do I need to run BLOOM-1B?

The smallest card in our catalogue that holds BLOOM-1B is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 1.8 GB, and produces roughly 36.9 tokens per second. 818 cards in total can run it.
