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 the numbers mean

What it takes to run this model

Minimum card

Tesla K20c

Memory needed

4.1 GB

Fastest

484 tok/s

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

The smallest card that holds it is the Tesla K20c with 5 GB, running it at Q3_K_M and producing around 28.9 tokens per second.

At the other end, a B200 generates roughly 484 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

Where it came from

MPT-7B was published by MosaicML, in United States of America, in May 2023. industry is the category the publisher falls under.

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

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 mosaicml organisation on Hugging Face.

Understanding the speeds

Half the cards that hold it manage more than 26.1 tokens per second, and 559 exceed reading speed outright.

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.

What went into building it

Producing it required around 4.2 × 10²² FLOP of arithmetic, on NVIDIA A100 SXM4 40 GB, which is a statement about the training budget rather than about inference.

Step by step

How to choose a GPU for MPT-7B

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

  1. 01

    Read the memory figure first

    Look at what MPT-7B actually needs — around 4.1 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Decide how long your conversations run

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

  3. 03

    Set a quality floor

    The quantisation column varies by card, because a bigger card holds a more accurate copy of MPT-7B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Rank by throughput rather than spec sheet

    Ranking by tokens per second for MPT-7B follows memory bandwidth, not core counts, which is why the B200 tops it at 484 tok/s.

  5. 05

    Look at the headroom, not just the fit

    Tight means MPT-7B 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

    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 MPT-7B alone — a card is usually bought for more than one model.

Answers

MPT-7B — common questions

01

Can I run MPT-7B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 8.2 GB and generating roughly 68.4 tokens per second — a comfortable fit.

02

Can I run MPT-7B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 8.2 GB and generating roughly 81.1 tokens per second — a comfortable fit.

03

Is MPT-7B open source?

Its weights are published, so MPT-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.

04

How many parameters does MPT-7B have?

MPT-7B has 7B 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.

05

Who created MPT-7B?

MPT-7B was published by MosaicML, based in United States of America, categorised as industry.

06

When was MPT-7B released?

MPT-7B was published in May 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 MPT-7B used for?

MPT-7B works in Language, and is recorded as handling language modeling/generation, Question answering. 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 MPT-7B?

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

09

How much compute was used to train MPT-7B?

Around 4.2 × 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.

10

Can I run MPT-7B if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down — the nearest miss we calculate is short by 1.3 GB. Our figures for MPT-7B assume it is fully resident.

11

Would two GPUs run MPT-7B faster?

Two cards buy memory rather than speed. That matters for MPT-7B only if one card cannot hold it — 589 can, so a second adds little.

12

Why does the quantisation differ between cards for MPT-7B?

Because capacity varies, so does how hard MPT-7B has to be squeezed — 4 distinct levels appear in the table above. Set a minimum quality to compare at one.

13

How accurate are these MPT-7B speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 290–774 tok/s on the B200 rather than a single number.

14

What GPU do I need to run MPT-7B?

The smallest card in our catalogue that holds MPT-7B is the Tesla K20c, with 5 GB of memory. It runs the model at Q3_K_M using about 4.1 GB, and produces roughly 28.9 tokens per second. 589 cards in total can run it.

15

How fast is MPT-7B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 484 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 559 of the cards that can run MPT-7B clear that.

16

How much VRAM does MPT-7B need?

About 4.1 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.

17

Can I run MPT-7B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q6_K, using about 6.6 GB and generating roughly 131 tokens per second — a tight fit.

18

Can I run MPT-7B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 8.2 GB and generating roughly 55.2 tokens per second — a comfortable fit.
