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.

The extremes

The ten fastest GPUs that run MolmoAct-7B-D

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

Minimum card

Memory needed

4.1 GB

Fastest

484 tok/s

MolmoAct-7B-D 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 least hardware that works is a Tesla K20c. Its 5 GB is enough at Q3_K_M compression, giving roughly 28.9 tokens per second.

A B200 is the fastest we calculate for it: about 484 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

MolmoAct-7B-D was published by Allen Institute for AI,University of Washington, in United States of America, in August 2025. research collective,Academia is the category the publisher falls under.

It works in Robotics, and is recorded as doing robotic manipulation.

It builds on Qwen2.5-7B,SigLIP 400M, which is why it shares that model's general shape and size.

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 allenai organisation on Hugging Face.

How fast it runs, and why

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.

Step by step

How to choose a GPU for MolmoAct-7B-D

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

01

Read the memory figure first

The table lists every card that can hold MolmoAct-7B-D — around 4.1 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Set the context length you will work at

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for MolmoAct-7B-D.
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 MolmoAct-7B-D by squeezing it further than you would want.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second for MolmoAct-7B-D follows memory bandwidth, not core counts, which is why the B200 tops it at 484 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage MolmoAct-7B-D from those with room to spare. Buy for the second if the context might grow.
06

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for MolmoAct-7B-D alone — a card is usually bought for more than one model.

Answers

MolmoAct-7B-D — common questions

How many parameters does MolmoAct-7B-D have?

MolmoAct-7B-D has 7B parameters. 7B. 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.

Who created MolmoAct-7B-D?

MolmoAct-7B-D was published by Allen Institute for AI,University of Washington, based in United States of America, categorised as research collective,Academia.

When was MolmoAct-7B-D released?

MolmoAct-7B-D was published in August 2025.

What is MolmoAct-7B-D used for?

MolmoAct-7B-D works in Robotics, and is recorded as handling robotic manipulation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download MolmoAct-7B-D?

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

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

It can be split between the card and system memory, but MolmoAct-7B-D generates painfully slowly that way — the nearest miss we calculate is short by 1.3 GB. Nothing on this page assumes offloading.

Would two GPUs run MolmoAct-7B-D faster?

A second card roughly doubles the memory available but not the generation rate. With 589 cards already able to run MolmoAct-7B-D alone, the case for pairing is weak.

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

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

How accurate are these MolmoAct-7B-D 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.

What GPU do I need to run MolmoAct-7B-D?

The smallest card in our catalogue that holds MolmoAct-7B-D 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.

How fast is MolmoAct-7B-D 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 MolmoAct-7B-D clear that.

How much VRAM does MolmoAct-7B-D 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.

Can I run MolmoAct-7B-D 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.

Can I run MolmoAct-7B-D 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.

Can I run MolmoAct-7B-D 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.

Can I run MolmoAct-7B-D 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.

Is MolmoAct-7B-D open source?

Its weights are published, so MolmoAct-7B-D 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.
