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 OmniGen

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 OmniGen

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

The hardware side

Minimum card

Tesla C1080

Memory needed

3.4 GB

Fastest

892 tok/s

OmniGen is small enough at 3.8B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

At the low end, a Tesla C1080 handles it — 4 GB, at Q5_K_M, for about 17.3 tokens per second.

At the other end, a B200 generates roughly 892 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

What this model is

OmniGen was published by Beijing Academy of Artificial Intelligence / BAAI, in China, in September 2024. The organisation is categorised as academia.

It works in Image generation, and is recorded as doing image generation.

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.

What decides the speed

The median result is around 29.9 tokens per second; 777 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.

Step by step

How to choose a GPU for OmniGen

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

Look at what OmniGen actually needs — around 3.4 GB at Q5_K_M. No amount of processing power compensates for a card that cannot hold it.
02

Match the context to your actual use

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason OmniGen stops fitting a card that seemed fine.
03

Set a quality floor

Each card runs the least-compressed copy it can hold — Q5_K_M on the smallest card that fits. Setting a floor drops the cards that only manage OmniGen by squeezing it further than you would want.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second for OmniGen follows memory bandwidth, not core counts, which is why the B200 tops it at 892 tok/s.
05

Check the fit verdict before buying

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

Open the card you have settled on

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond OmniGen.

Answers

OmniGen — common questions

How much VRAM does OmniGen need?

About 3.4 GB at Q5_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 OmniGen on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 4.8 GB and generating roughly 166 tokens per second — a comfortable fit.

Can I run OmniGen on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 4.8 GB and generating roughly 102 tokens per second — a comfortable fit.

Can I run OmniGen on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 4.8 GB and generating roughly 126 tokens per second — a comfortable fit.

Can I run OmniGen on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 4.8 GB and generating roughly 149 tokens per second — a comfortable fit.

Is OmniGen open source?

Its weights are published, so OmniGen 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 OmniGen have?

OmniGen has 3.8B parameters. Table 2. 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 OmniGen?

OmniGen was published by Beijing Academy of Artificial Intelligence / BAAI, based in China, categorised as academia.

When was OmniGen released?

OmniGen was published in September 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

What is OmniGen used for?

OmniGen works in Image generation, and is recorded as handling image generation. 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 OmniGen?

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

Can I run OmniGen 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 OmniGen is rarely worth using. Every figure here assumes the whole model is on the card.

Would two GPUs run OmniGen faster?

Two cards buy memory rather than speed. That matters for OmniGen only if one card cannot hold it — 818 can, so a second adds little.

Why does the quantisation differ between cards for OmniGen?

Each card is shown running the least-compressed copy it can hold, and OmniGen appears at 3 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these OmniGen speed estimates?

These are estimates with real error bars. The fastest result here, 535–1,427 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 OmniGen?

The smallest card in our catalogue that holds OmniGen is the Tesla C1080, with 4 GB of memory. It runs the model at Q5_K_M using about 3.4 GB, and produces roughly 17.3 tokens per second. 818 cards in total can run it.

How fast is OmniGen on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 892 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 777 of the cards that can run OmniGen clear that.
