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 Japanese-GPT-1B

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 Japanese-GPT-1B

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

2.1 GB

Fastest

2,606 tok/s

Japanese-GPT-1B is small enough at 1.3B 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 Q8_0, for about 28.4 tokens per second.

At the other end, a B200 generates roughly 2,606 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

What this model is

Japanese-GPT-1B was published by rinna, in Japan, in January 2022. industry is the category the publisher falls under.

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

Across every card that can run it, the middle of the range is about 73.2 tokens per second, and 797 of them clear the ten tokens per second that roughly matches reading speed.

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

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Step by step

How to choose a GPU for Japanese-GPT-1B

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

The table lists every card that can hold Japanese-GPT-1B — around 2.1 GB at Q8_0. That figure, not the card's headline performance, is what decides whether it runs.
02

Match the context to your actual use

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Japanese-GPT-1B can slip off a card that handles short questions easily.
03

Set a quality floor

Each card runs the least-compressed copy it can hold — Q8_0 on the smallest card that fits. Setting a floor drops the cards that only manage Japanese-GPT-1B by squeezing it further than you would want.
04

Compare tokens per second, not specifications

Ranking by tokens per second for Japanese-GPT-1B follows memory bandwidth, not core counts, which is why the B200 tops it at 2,606 tok/s.
05

Read the fit column last

The fit column separates cards that just manage Japanese-GPT-1B from those with room to spare. Buy for the second if the context might grow.
06

Open the card you have settled on

Following a card through to its own page shows every other model it can hold, which is the question that follows once Japanese-GPT-1B is settled.

Answers

Japanese-GPT-1B — common questions

Can I run Japanese-GPT-1B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 2.1 GB and generating roughly 368 tokens per second — a comfortable fit.

Can I run Japanese-GPT-1B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 2.1 GB and generating roughly 437 tokens per second — a comfortable fit.

Is Japanese-GPT-1B open source?

Its weights are published, so Japanese-GPT-1B 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 Japanese-GPT-1B have?

Japanese-GPT-1B has 1.3B 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 Japanese-GPT-1B?

Japanese-GPT-1B was published by rinna, based in Japan, categorised as industry.

When was Japanese-GPT-1B released?

Japanese-GPT-1B was published in January 2022. 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 Japanese-GPT-1B used for?

Japanese-GPT-1B works in Language, and is recorded as handling language modeling/generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Japanese-GPT-1B?

The weights for Japanese-GPT-1B 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 Japanese-GPT-1B if it does not fit in my GPU?

It can be split between the card and system memory, but Japanese-GPT-1B generates painfully slowly that way. Nothing on this page assumes offloading.

Would two GPUs run Japanese-GPT-1B faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run Japanese-GPT-1B alone, the case for pairing is weak.

Why does the quantisation differ between cards for Japanese-GPT-1B?

A larger card holds a more accurate copy. Across the cards that run Japanese-GPT-1B, 1 compression levels are used; the floor control above pins it to one.

How accurate are these Japanese-GPT-1B speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 1,564–4,170 tok/s on the B200 rather than a single number.

What GPU do I need to run Japanese-GPT-1B?

The smallest card in our catalogue that holds Japanese-GPT-1B is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 2.1 GB, and produces roughly 28.4 tokens per second. 818 cards in total can run it.

How fast is Japanese-GPT-1B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 2,606 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 797 of the cards that can run Japanese-GPT-1B clear that.

How much VRAM does Japanese-GPT-1B need?

About 2.1 GB at Q8_0 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 Japanese-GPT-1B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 2.1 GB and generating roughly 485 tokens per second — a comfortable fit.

Can I run Japanese-GPT-1B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 2.1 GB and generating roughly 297 tokens per second — a comfortable fit.
