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 HAMSTER VLM

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.

The smallest GPUs that still run HAMSTER VLM

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

What it takes to run this model

Minimum card

P102-101

Memory needed

8.9 GB

Fastest

251 tok/s

HAMSTER VLM is small enough at 13.5B parameters that hardware is rarely the obstacle — 306 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the P102-101 with 10 GB, running it at Q4_K_M and producing around 19.7 tokens per second.

The quickest result comes from a B200 at around 251 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Where it came from

HAMSTER VLM was published by NVIDIA,University of Washington,University of Southern California, in United States of America, in February 2025. It comes out of industry,Academia,Academia.

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

It builds on VILA1.5-13B, which is why it shares that model's general shape and size.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.

Understanding the speeds

The median result is around 21.1 tokens per second; 269 cards produce text faster than most people read it.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

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

Producing it required around 2.4 × 10²¹ FLOP of arithmetic, on NVIDIA A100 SXM4 80 GB, which is a statement about the training budget rather than about inference.

Step by step

How to choose a GPU for HAMSTER VLM

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

01

Start from the memory column

The table lists every card that can hold HAMSTER VLM — around 8.9 GB at Q4_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Match the context to your actual use

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for HAMSTER VLM.
03

Decide how much compression you will accept

Each card runs the least-compressed copy it can hold — Q4_K_M on the smallest card that fits. Setting a floor drops the cards that only manage HAMSTER VLM by squeezing it further than you would want.
04

Compare tokens per second, not specifications

Sort by speed to see how cards rank for HAMSTER VLM. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 251 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs HAMSTER VLM but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
06

See what else that card runs

Following a card through to its own page shows every other model it can hold, which is the question that follows once HAMSTER VLM is settled.

Answers

HAMSTER VLM — common questions

How fast is HAMSTER VLM on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 251 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 269 of the cards that can run HAMSTER VLM clear that.

How much VRAM does HAMSTER VLM need?

About 8.9 GB at Q4_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 HAMSTER VLM on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 10.4 GB and generating roughly 51.1 tokens per second — a tight fit.

Can I run HAMSTER VLM on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 12.0 GB and generating roughly 51.5 tokens per second — a tight fit.

Can I run HAMSTER VLM on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 15.1 GB and generating roughly 42.1 tokens per second — a comfortable fit.

Is HAMSTER VLM open source?

Its weights are published, so HAMSTER VLM 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.

How many parameters does HAMSTER VLM have?

HAMSTER VLM has 13.5B parameters. https://huggingface.co/yili18/Hamster_dev VLM: VILA 1.5-13b, 13493916736 parameters policy: either RVT-2 or 3D-DA this record is for the HAMSTER VLM, so the policy is not included. 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 HAMSTER VLM?

HAMSTER VLM was published by NVIDIA,University of Washington,University of Southern California, based in United States of America, categorised as industry,Academia,Academia.

When was HAMSTER VLM released?

HAMSTER VLM was published in February 2025.

What is HAMSTER VLM used for?

HAMSTER VLM works in Robotics, and is recorded as handling robotic manipulation. 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.

Where can I download HAMSTER VLM?

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

How much compute was used to train HAMSTER VLM?

Around 2.4 × 10²¹ FLOP, on NVIDIA A100 SXM4 80 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.

Can I run HAMSTER VLM 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 1.7 GB. Our figures for HAMSTER VLM assume it is fully resident.

Would two GPUs run HAMSTER VLM faster?

Capacity adds across cards; throughput does not. Since 306 of the cards we track already hold HAMSTER VLM on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for HAMSTER VLM?

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

How accurate are these HAMSTER VLM speed estimates?

These are estimates with real error bars. The fastest result here, 151–402 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

What GPU do I need to run HAMSTER VLM?

The smallest card in our catalogue that holds HAMSTER VLM is the P102-101, with 10 GB of memory. It runs the model at Q4_K_M using about 8.9 GB, and produces roughly 19.7 tokens per second. 306 cards in total can run it.
