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 Vicuna-13B-v1.5

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 Vicuna-13B-v1.5

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

Xeon Phi 5110P

Memory needed

7.1 GB

Fastest

261 tok/s

Vicuna-13B-v1.5 is small enough at 13B parameters that hardware is rarely the obstacle — 509 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the Xeon Phi 5110P with 8 GB, running it at Q3_K_M and producing around 18.3 tokens per second.

A B200 is the fastest we calculate for it: about 261 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

Vicuna-13B-v1.5 was published by Large Model Systems Organization,University of California (UC) Berkeley, in United States of America, in August 2023. academia,Academia is the category the publisher falls under.

It works in Language, and is recorded as doing language modeling/generation, Chat.

It builds on Llama 2-13B, which is why it shares that 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.

How fast it runs, and why

Across every card that can run it, the middle of the range is about 21.2 tokens per second, and 459 of them clear the ten tokens per second that roughly matches reading speed.

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 Vicuna-13B-v1.5

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

01

Read the memory figure first

The table lists every card that can hold Vicuna-13B-v1.5 — around 7.1 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Decide how long your conversations run

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Vicuna-13B-v1.5 stops fitting a card that seemed fine.
03

Decide how much compression you will accept

Each card runs the least-compressed copy it can hold — Q3_K_M on the smallest card that fits. Setting a floor drops the cards that only manage Vicuna-13B-v1.5 by squeezing it further than you would want.
04

Sort by speed

The speed ordering for Vicuna-13B-v1.5 is effectively an ordering by memory bandwidth, which is why the B200 tops it at 261 tok/s.
05

Look at the headroom, not just the fit

The fit column separates cards that just manage Vicuna-13B-v1.5 from those with room to spare. Buy for the second if the context might grow.
06

Check the card from the other side

Following a card through to its own page shows every other model it can hold, which is the question that follows once Vicuna-13B-v1.5 is settled.

Answers

Vicuna-13B-v1.5 — common questions

Can I run Vicuna-13B-v1.5 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 3.2 GB. Our figures for Vicuna-13B-v1.5 assume it is fully resident.

Would two GPUs run Vicuna-13B-v1.5 faster?

Capacity adds across cards; throughput does not. Since 509 of the cards we track already hold Vicuna-13B-v1.5 on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Vicuna-13B-v1.5?

Each card is shown running the least-compressed copy it can hold, and Vicuna-13B-v1.5 appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Vicuna-13B-v1.5 speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 156–417 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

What GPU do I need to run Vicuna-13B-v1.5?

The smallest card in our catalogue that holds Vicuna-13B-v1.5 is the Xeon Phi 5110P, with 8 GB of memory. It runs the model at Q3_K_M using about 7.1 GB, and produces roughly 18.3 tokens per second. 509 cards in total can run it.

How fast is Vicuna-13B-v1.5 on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 261 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 459 of the cards that can run Vicuna-13B-v1.5 clear that.

How much VRAM does Vicuna-13B-v1.5 need?

About 7.1 GB at Q3_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 Vicuna-13B-v1.5 on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q3_K_M, using about 7.1 GB and generating roughly 131 tokens per second — a tight fit.

Can I run Vicuna-13B-v1.5 on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 10.1 GB and generating roughly 53.1 tokens per second — a tight fit.

Can I run Vicuna-13B-v1.5 on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 11.6 GB and generating roughly 53.5 tokens per second — a comfortable fit.

Can I run Vicuna-13B-v1.5 on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 14.6 GB and generating roughly 43.7 tokens per second — a comfortable fit.

Is Vicuna-13B-v1.5 open source?

Its weights are published, so Vicuna-13B-v1.5 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 Vicuna-13B-v1.5 have?

Vicuna-13B-v1.5 has 13B parameters. 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 Vicuna-13B-v1.5?

Vicuna-13B-v1.5 was published by Large Model Systems Organization,University of California (UC) Berkeley, based in United States of America, categorised as academia,Academia.

When was Vicuna-13B-v1.5 released?

Vicuna-13B-v1.5 was published in August 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.

What is Vicuna-13B-v1.5 used for?

Vicuna-13B-v1.5 works in Language, and is recorded as handling language modeling/generation, Chat. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Vicuna-13B-v1.5?

The weights for Vicuna-13B-v1.5 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
