Llama 2-34B

Closed weights Meta AI 34B parameters July 2023

No estimate

No hardware requirements for this model

The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Parameters

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

Training compute
4.1 × 10²³ FLOP

All models sizes trained on 2.0T tokens, per table 1 2T * 34b * 6 = 4.08e23 Also trained on 1038336 A100-hours, which is 3.5e23 at 30% utilization. So the utilization was probably around 35%.

What the numbers mean

About this model

Llama 2-34B was published by Meta AI, in United States of America, in July 2023. It comes out of industry.

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

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

Training and provenance

Training it took roughly 4.1 × 10²³ FLOP of computation, on NVIDIA A100 SXM4 80 GB — a measure of what producing the model cost, not of how fast it answers.

Around 2,000,000,000,000 tokens went into training it.

The reason it appears in this catalogue at all is highly cited.

Answers

Llama 2-34B — common questions

01

Is Llama 2-34B open source?

No. Llama 2-34B has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does Llama 2-34B have?

Llama 2-34B has 34B parameters. Llama has been released in 7B, 13B, 34B, and 70B variants. 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.

03

Who created Llama 2-34B?

Llama 2-34B was published by Meta AI, based in United States of America, categorised as industry.

04

When was Llama 2-34B released?

Llama 2-34B was published in July 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.

05

What is Llama 2-34B used for?

Llama 2-34B works in Language, and is recorded as handling language modeling. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

How much compute was used to train Llama 2-34B?

Around 4.1 × 10²³ FLOP, on NVIDIA A100 SXM4 80 GB. 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.

07

What GPU do I need to run Llama 2-34B?

None. Llama 2-34B is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.

Looking at it from the other side?

This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
