What the numbers mean

What you need to run it

Minimum card

GeForce GTX 1080 Ti

Memory needed

9.0 GB

Fastest

199 tok/s

CogVLM-17B reaches a parameter count of 17B. 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: 295.

The least hardware that works is GeForce GTX 1080 Ti, with a memory capacity of 11 GB, running it at a compression of Q3_K_M and producing around 27.7 tokens per second.

The quickest result comes from B200, generating roughly 199 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

CogVLM-17B was published by Tsinghua University,Z.ai (Zhipu AI),Beihang University, in the country recorded as China, during November 2023. The publishing organisation is categorised as academia,Industry,Academia.

It works in the domain of Multimodal, Vision, Language, and is recorded as performing the task of image captioning, Visual question answering, Chat.

Rather than being trained from scratch, it is derived from Vicuna-7B v0. That is why it shares the base model's general shape and size.

The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold.

Reading the throughput figures

Half the cards that hold it manage more than 20.6 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 251 of them.

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

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.

What went into building it

The training run consumed about 6.3 × 10²² FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Its inclusion criterion: sOTA improvement.

Step by step

How to choose a GPU for CogVLM-17B

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

  1. 01

    Start from the memory column

    The table lists every card able to hold CogVLM-17B, needing around 9.0 GB at a compression of Q3_K_M. That figure, not the headline performance of a card, is what decides whether it runs.

  2. 02

    Set the context length you will work at

    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 CogVLM-17B.

  3. 03

    Choose how far you will compress it

    Each card runs the least-compressed copy it can hold, 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.

  4. 04

    Compare tokens per second, not specifications

    Sort by speed to see how cards rank for CogVLM-17B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 199 tok/s.

  5. 05

    Read the fit column last

    Tight means it loads and works with no room to raise the context later, in the case of CogVLM-17B. 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.

  6. 06

    Open the card you have settled on

    Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond CogVLM-17B.

Answers

CogVLM-17B — common questions

01

CogVLM-17B— 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: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

02

CogVLM-17B— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 120–319 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

03

CogVLM-17B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is GeForce GTX 1080 Ti, with a memory capacity of 11 GB. It runs the model at a compression of Q3_K_M using about 9.0 GB, and produces roughly 27.7 tokens per second. The number of cards able to run it in total: 295.

04

CogVLM-17B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 199 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: 251.

05

CogVLM-17B— how much VRAM does it need?

It needs about 9.0 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.

06

CogVLM-17B— 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 IQ4_XS, using about 10.0 GB and generating roughly 55.8 tokens per second. The fit is tight.

07

CogVLM-17B— 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 Q5_K_M, using about 13.0 GB and generating roughly 50.3 tokens per second. The fit is tight.

08

CogVLM-17B— 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 18.9 GB and generating roughly 33.4 tokens per second. The fit is tight.

09

CogVLM-17B— 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.

10

CogVLM-17B— how many parameters does it have?

It has a parameter count of 17B. CogVLM-17B has 10 billion vision parameters and 7 billion language parameters. However, "the total number of trainable parameters is 6.5B". "CogVLM model comprises four fundamental components: a vision transformer (ViT) encoder, an MLP adapter, a pretrained large language model (GPT), and a visual expert module." ViT: EVA2-CLIP-E, last layer removed (5B params with last layer, non-trainable) MLP adapter: 2 layers, parameter count unavailable GPT: Vicuna1.5-7B (7B params) Visual expert module: parameter count unclear. 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.

11

CogVLM-17B— who created it?

It was published by Tsinghua University,Z.ai (Zhipu AI),Beihang University, based in China, an organisation categorised as academia,Industry,Academia.

12

CogVLM-17B— when was it released?

It was published in November 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

13

CogVLM-17B— what is it used for?

It works in the domain of Multimodal, Vision, Language, and is recorded as handling the task of image captioning, Visual question answering, Chat. 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.

14

CogVLM-17B— where can I download it?

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

15

CogVLM-17B— how much compute was used to train it?

Training consumed around 6.3 × 10²² FLOP. 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.

16

CogVLM-17B— 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 2.0 GB. Every figure here assumes the whole model is resident on the card.

17

CogVLM-17B— 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: 295. So a second card is rarely the answer here.
