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

What the numbers mean

What you need to run it

Minimum card

RTX A4500

Memory needed

17.3 GB

Fastest

99.7 tok/s

With 34B parameters, Yi-1.5-34B lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.

The least hardware that works is a RTX A4500. Its 20 GB is enough at Q3_K_M compression, giving roughly 21.5 tokens per second.

A B200 is the fastest we calculate for it: about 99.7 tokens per second, from 8,000 GB/s of memory bandwidth.

Where it came from

Yi-1.5-34B was published by 01.AI, in China, in May 2024. It comes out of industry.

It works in Language, and is recorded as doing chat, Language modeling/generation, Translation, Code generation.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. It is published under the 01-ai organisation on Hugging Face.

Understanding the speeds

Across every card that can run it, the middle of the range is about 21.2 tokens per second, and 103 of them clear the ten tokens per second that roughly matches reading speed.

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.

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.

Training and provenance

Producing it required around 7.3 × 10²³ FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Step by step

How to choose a GPU for Yi-1.5-34B

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

  1. 01

    Check what it needs before anything else

    Look at what Yi-1.5-34B actually needs — around 17.3 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Match the context to your actual use

    Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Yi-1.5-34B.

  3. 03

    Set a quality floor

    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 Yi-1.5-34B by squeezing it further than you would want.

  4. 04

    Compare tokens per second, not specifications

    Sort by speed to see how cards rank for Yi-1.5-34B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 99.7 tok/s.

  5. 05

    Check the fit verdict before buying

    Tight means Yi-1.5-34B loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.

  6. 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 Yi-1.5-34B is settled.

Answers

Yi-1.5-34B — common questions

01

Can I run Yi-1.5-34B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 21.3 GB and generating roughly 38.5 tokens per second — a tight fit.

02

Is Yi-1.5-34B open source?

Its weights are published, so Yi-1.5-34B 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.

03

How many parameters does Yi-1.5-34B have?

Yi-1.5-34B has 34B parameters. 34b. 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.

04

Who created Yi-1.5-34B?

Yi-1.5-34B was published by 01.AI, based in China, categorised as industry.

05

When was Yi-1.5-34B released?

Yi-1.5-34B was published in May 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.

06

What is Yi-1.5-34B used for?

Yi-1.5-34B works in Language, and is recorded as handling chat, Language modeling/generation, Translation, Code 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.

07

Where can I download Yi-1.5-34B?

Its weights are published under the 01-ai organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.

08

How much compute was used to train Yi-1.5-34B?

Around 7.3 × 10²³ 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.

09

Can I run Yi-1.5-34B 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 Yi-1.5-34B is rarely worth using — the nearest miss we calculate is short by 6.9 GB. Every figure here assumes the whole model is on the card.

10

Would two GPUs run Yi-1.5-34B faster?

Two cards buy memory rather than speed. That matters for Yi-1.5-34B only if one card cannot hold it — 132 can, so a second adds little.

11

Why does the quantisation differ between cards for Yi-1.5-34B?

Because capacity varies, so does how hard Yi-1.5-34B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

12

How accurate are these Yi-1.5-34B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 60–159 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.

13

What GPU do I need to run Yi-1.5-34B?

The smallest card in our catalogue that holds Yi-1.5-34B is the RTX A4500, with 20 GB of memory. It runs the model at Q3_K_M using about 17.3 GB, and produces roughly 21.5 tokens per second. 132 cards in total can run it.

14

How fast is Yi-1.5-34B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 99.7 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 103 of the cards that can run Yi-1.5-34B clear that.

15

How much VRAM does Yi-1.5-34B need?

About 17.3 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.
