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 Cosmos-Transfer2.5-2B

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 Cosmos-Transfer2.5-2B

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

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

2.8 GB

Fastest

1,694 tok/s

Cosmos-Transfer2.5-2B reaches a parameter count of 2B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 818.

The entry point is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 18.4 tokens per second.

The fastest we calculate for it is B200, generating roughly 1,694 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

Cosmos-Transfer2.5-2B was published by NVIDIA, in the country recorded as United States of America, during September 2025. The publishing organisation is categorised as industry.

It works in the domain of Video, Image generation, and is recorded as performing the task of video generation, Text-to-video, Image-to-video, Image generation, Text-to-image, Video-to-video.

It builds on Cosmos-Predict2.5 2B. Most models at this scale are adapted from an existing base rather than built from nothing.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. On Hugging Face it is published under the organisation nvidia.

Understanding the speeds

Across every card that can run it, the middle of the range sits at 47.6 tokens per second. Exceeding reading speed outright: 789 of them.

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 Cosmos-Transfer2.5-2B

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

Every card here has been checked against Cosmos-Transfer2.5-2B, needing around 2.8 GB at a compression of Q8_0. No amount of processing power compensates for a card that cannot hold it.
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 Cosmos-Transfer2.5-2B.
03

Set a quality floor

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of Q8_0 on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Rank by throughput rather than spec sheet

Sort by speed to see how cards rank for Cosmos-Transfer2.5-2B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 1,694 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage it from those with room to spare, in the case of Cosmos-Transfer2.5-2B. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
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. A card is usually bought for more than one model, so it is worth a look before buying for Cosmos-Transfer2.5-2B.

Answers

Cosmos-Transfer2.5-2B — common questions

Cosmos-Transfer2.5-2B— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q8_0, using about 2.8 GB and generating roughly 239 tokens per second. The fit is comfortable.

Cosmos-Transfer2.5-2B— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q8_0, using about 2.8 GB and generating roughly 284 tokens per second. The fit is comfortable.

Cosmos-Transfer2.5-2B— is it open source?

Its weights are published, so it 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.

Cosmos-Transfer2.5-2B— how many parameters does it have?

It has a parameter count of 2B. 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.

Cosmos-Transfer2.5-2B— who created it?

It was published by NVIDIA, based in United States of America, an organisation categorised as industry.

Cosmos-Transfer2.5-2B— when was it released?

It was published in September 2025.

Cosmos-Transfer2.5-2B— what is it used for?

It works in the domain of Video, Image generation, and is recorded as handling the task of video generation, Text-to-video, Image-to-video, Image generation, Text-to-image, Video-to-video. 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.

Cosmos-Transfer2.5-2B— where can I download it?

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

Cosmos-Transfer2.5-2B— can I run it 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 model is rarely worth using. Every figure here assumes the whole model is resident on the card.

Cosmos-Transfer2.5-2B— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 818. So a second card is rarely the answer here.

Cosmos-Transfer2.5-2B— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Cosmos-Transfer2.5-2B— how accurate are these speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked, which is why each is published as a range rather than a single number. One example: 1,016–2,711 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Cosmos-Transfer2.5-2B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q8_0 using about 2.8 GB, and produces roughly 18.4 tokens per second. The number of cards able to run it in total: 818.

Cosmos-Transfer2.5-2B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 1,694 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 789.

Cosmos-Transfer2.5-2B— how much VRAM does it need?

It needs about 2.8 GB at a compression of Q8_0, 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.

Cosmos-Transfer2.5-2B— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q8_0, using about 2.8 GB and generating roughly 316 tokens per second. The fit is comfortable.

Cosmos-Transfer2.5-2B— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q8_0, using about 2.8 GB and generating roughly 193 tokens per second. The fit is comfortable.
