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.

With 30B parameters, Jais-30b (phase 1) lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.

The entry point is the RTX A4500: 20 GB of memory, IQ4_XS compression, roughly 22.2 tokens per second.

Top of the range is the B200, at roughly 113 tokens per second thanks to 8,000 GB/s of bandwidth.

What this model is

Jais-30b (phase 1) was published by Cerebras Systems,Mohamed bin Zayed University of Artificial Intelligence (MBZUAI),Inception G42,G42, in United States of America, in November 2023. The organisation is categorised as industry,Academia,Industry,Industry.

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

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. It is published under the inceptionai organisation on Hugging Face.

What decides the speed

Across every card that can run it, the middle of the range is about 22.0 tokens per second, and 104 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.

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.

What went into building it

Training it took roughly 1 × 10²³ FLOP of computation, on Cerebras CS-2 — a measure of what producing the model cost, not of how fast it answers.

The training set ran to roughly 427,000,000,000 tokens.

Step by step

How to choose a GPU for Jais-30b (phase 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

    Every card here has been checked against Jais-30b (phase 1) — around 17.1 GB at IQ4_XS. 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 Jais-30b (phase 1) stops fitting a card that seemed fine.

  3. 03

    Decide how much compression you will accept

    Compression is what makes Jais-30b (phase 1) 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.

  4. 04

    Compare tokens per second, not specifications

    Ranking by tokens per second for Jais-30b (phase 1) follows memory bandwidth, not core counts, which is why the B200 tops it at 113 tok/s.

  5. 05

    Read the fit column last

    The fit column separates cards that just manage Jais-30b (phase 1) 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 Jais-30b (phase 1) alone — a card is usually bought for more than one model.

Answers

Jais-30b (phase 1) — common questions

01

How accurate are these Jais-30b (phase 1) speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 68–181 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.

02

What GPU do I need to run Jais-30b (phase 1)?

The smallest card in our catalogue that holds Jais-30b (phase 1) is the RTX A4500, with 20 GB of memory. It runs the model at IQ4_XS using about 17.1 GB, and produces roughly 22.2 tokens per second. 132 cards in total can run it.

03

How fast is Jais-30b (phase 1) on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 113 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 104 of the cards that can run Jais-30b (phase 1) clear that.

04

How much VRAM does Jais-30b (phase 1) need?

About 17.1 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.

05

Can I run Jais-30b (phase 1) on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 18.8 GB and generating roughly 43.7 tokens per second — a tight fit.

06

Is Jais-30b (phase 1) open source?

Its weights are published, so Jais-30b (phase 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.

07

How many parameters does Jais-30b (phase 1) have?

Jais-30b (phase 1) has 30B parameters. 30B "The backbone of Jais-30B is a causal decoder-only large language model. It is engineered with 48 transformer blocks, 56 attention heads, and an embedding dimension of 7168. ". 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.

08

Who created Jais-30b (phase 1)?

Jais-30b (phase 1) was published by Cerebras Systems,Mohamed bin Zayed University of Artificial Intelligence (MBZUAI),Inception G42,G42, based in United States of America, categorised as industry,Academia,Industry,Industry.

09

When was Jais-30b (phase 1) released?

Jais-30b (phase 1) was published in November 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.

10

What is Jais-30b (phase 1) used for?

Jais-30b (phase 1) works in Language, and is recorded as handling language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

11

Where can I download Jais-30b (phase 1)?

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

12

How much compute was used to train Jais-30b (phase 1)?

Around 1 × 10²³ FLOP, on Cerebras CS-2. 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.

13

Can I run Jais-30b (phase 1) 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 Jais-30b (phase 1) is rarely worth using — the nearest miss we calculate is short by 4.4 GB. Every figure here assumes the whole model is on the card.

14

Would two GPUs run Jais-30b (phase 1) faster?

Two cards buy memory rather than speed. That matters for Jais-30b (phase 1) only if one card cannot hold it — 132 can, so a second adds little.

15

Why does the quantisation differ between cards for Jais-30b (phase 1)?

Because capacity varies, so does how hard Jais-30b (phase 1) has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.
