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 Ovis2.5 9B

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 Ovis2.5 9B

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

Quadro 6000

Memory needed

5.1 GB

Fastest

376 tok/s

Ovis2.5 9B reaches a parameter count of 9B. 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: 582.

The entry point is Quadro 6000, with a memory capacity of 6 GB, running it at a compression of Q3_K_M and producing around 15.5 tokens per second.

The quickest result comes from B200, generating roughly 376 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

Ovis2.5 9B was published by Alibaba, in the country recorded as China, during August 2025. The publishing organisation is categorised as industry.

It works in the domain of Multimodal, Language, Vision, Video, and is recorded as performing the task of language modeling/generation, Visual question answering, Question answering, Character recognition (OCR), Image captioning, Quantitative reasoning, Mathematical reasoning, Video description.

Its starting point was an existing base model, Qwen3-8B. That is why it shares the base model's general shape and size.

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. On Hugging Face it is published under the organisation AIDC-AI.

How fast it runs, and why

Half the cards that hold it manage more than 21.1 tokens per second. Exceeding reading speed outright: 541 of them.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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 Ovis2.5 9B

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

01

Check what it needs before anything else

Start from what it actually needs, which is the requirement of Ovis2.5 9B, needing around 5.1 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
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, because at long context a card that handles short questions easily can be dropped by Ovis2.5 9B.
03

Decide how much compression you will accept

Compression is what makes a model fit smaller cards, at some cost in accuracy, reaching a compression of Q3_K_M 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

Sort by speed

Ranking by tokens per second follows memory bandwidth rather than core counts, for Ovis2.5 9B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 376 tok/s.
05

Look at the headroom, not just the fit

Tight means it loads and works with no room to raise the context later, in the case of Ovis2.5 9B. 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

Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond Ovis2.5 9B.

Answers

Ovis2.5 9B — common questions

Ovis2.5 9B— who created it?

It was published by Alibaba, based in China, an organisation categorised as industry.

Ovis2.5 9B— when was it released?

It was published in August 2025.

Ovis2.5 9B— what is it used for?

It works in the domain of Multimodal, Language, Vision, Video, and is recorded as handling the task of language modeling/generation, Visual question answering, Question answering, Character recognition (OCR), Image captioning, Quantitative reasoning, Mathematical reasoning, Video description. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Ovis2.5 9B— where can I download it?

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

Ovis2.5 9B— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. The nearest miss we calculate falls short by 1.6 GB. Every figure here assumes the whole model is resident on the card.

Ovis2.5 9B— would two GPUs run it faster?

Two cards buy memory rather than speed, which matters only if one card cannot hold it. The number that can: 582. So a second card is rarely the answer here.

Ovis2.5 9B— 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: 4. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Ovis2.5 9B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 226–602 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Ovis2.5 9B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Quadro 6000, with a memory capacity of 6 GB. It runs the model at a compression of Q3_K_M using about 5.1 GB, and produces roughly 15.5 tokens per second. The number of cards able to run it in total: 582.

Ovis2.5 9B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 376 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: 541.

Ovis2.5 9B— how much VRAM does it need?

It needs about 5.1 GB at a compression of Q3_K_M, 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.

Ovis2.5 9B— 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 Q5_K_M, using about 7.2 GB and generating roughly 125 tokens per second. The fit is tight.

Ovis2.5 9B— 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 10.3 GB and generating roughly 42.9 tokens per second. The fit is tight.

Ovis2.5 9B— 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 10.3 GB and generating roughly 53.2 tokens per second. The fit is comfortable.

Ovis2.5 9B— 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 10.3 GB and generating roughly 63.1 tokens per second. The fit is comfortable.

Ovis2.5 9B— 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.

Ovis2.5 9B— how many parameters does it have?

It has a parameter count of 9B. 9B. 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.
