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 airoboros-l2-70b-2.1

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 airoboros-l2-70b-2.1

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

Minimum card

A100 PCIe 40 GB

Memory needed

Fastest

48.4 tok/s

airoboros-l2-70b-2.1 sits at 70B parameters, which puts it above consumer hardware and into the range where a card is bought for this purpose rather than repurposed for it. 61 of the cards we track can hold it.

The smallest card that holds it is the A100 PCIe 40 GB with 40 GB, running it at Q3_K_M and producing around 25.5 tokens per second.

The quickest result comes from a B200 at around 48.4 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

About this model

airoboros-l2-70b-2.1 was published by its authors, in August 2023.

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

It builds on Llama 2-70B, which is why it shares that model's general shape and size.

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 jondurbin organisation on Hugging Face.

How fast it runs, and why

The median result is around 17.1 tokens per second; 50 cards produce text faster than most people read it.

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

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 airoboros-l2-70b-2.1

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

01

Start from the memory column

Look at what airoboros-l2-70b-2.1 actually needs — around 34.9 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
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 airoboros-l2-70b-2.1 can slip off a card that handles short questions easily.
03

Set a quality floor

Compression is what makes airoboros-l2-70b-2.1 fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second for airoboros-l2-70b-2.1 follows memory bandwidth, not core counts, which is why the B200 tops it at 48.4 tok/s.
05

Check the fit verdict before buying

Tight means airoboros-l2-70b-2.1 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.
06

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for airoboros-l2-70b-2.1 alone — a card is usually bought for more than one model.

Answers

airoboros-l2-70b-2.1 — common questions

Is airoboros-l2-70b-2.1 open source?

Its weights are published, so airoboros-l2-70b-2.1 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 airoboros-l2-70b-2.1 have?

airoboros-l2-70b-2.1 has 70B parameters. same as llama 2 70b. 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.

When was airoboros-l2-70b-2.1 released?

airoboros-l2-70b-2.1 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 airoboros-l2-70b-2.1 used for?

airoboros-l2-70b-2.1 works in Language, and is recorded as handling language modeling/generation, Question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download airoboros-l2-70b-2.1?

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

Can I run airoboros-l2-70b-2.1 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 airoboros-l2-70b-2.1 is rarely worth using — the nearest miss we calculate is short by 14.2 GB. Every figure here assumes the whole model is on the card.

Would two GPUs run airoboros-l2-70b-2.1 faster?

Two cards buy memory rather than speed. That matters for airoboros-l2-70b-2.1 only if one card cannot hold it — 61 can, so a second adds little.

Why does the quantisation differ between cards for airoboros-l2-70b-2.1?

Each card is shown running the least-compressed copy it can hold, and airoboros-l2-70b-2.1 appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these airoboros-l2-70b-2.1 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 29–77 tok/s on the B200 rather than a single number.

What GPU do I need to run airoboros-l2-70b-2.1?

The smallest card in our catalogue that holds airoboros-l2-70b-2.1 is the A100 PCIe 40 GB, with 40 GB of memory. It runs the model at Q3_K_M using about 34.9 GB, and produces roughly 25.5 tokens per second. 61 cards in total can run it.

How fast is airoboros-l2-70b-2.1 on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 48.4 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 50 of the cards that can run airoboros-l2-70b-2.1 clear that.

How much VRAM does airoboros-l2-70b-2.1 need?

About 34.9 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.
