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.

What the numbers mean

About this model

HyperCLOVA 204B was published by NAVER, in Korea (Republic of), in September 2021. industry is the category the publisher falls under.

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

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

What went into building it

Training it took roughly 2 × 10²³ FLOP of computation, on NVIDIA A100 — a measure of what producing the model cost, not of how fast it answers.

Around 560,000,000,000 tokens went into training it.

It is tracked in the underlying dataset for one reason in particular: sOTA improvement.

Answers

HyperCLOVA 204B — common questions

01

Is HyperCLOVA 204B open source?

No. HyperCLOVA 204B has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does HyperCLOVA 204B have?

HyperCLOVA 204B has 204B parameters. https://www.navercorp.com/navercorp_/ir/announce/2023/NAVER_CEO%20letter%20to%20shareholders_Aug%202023_Eng.pdf. 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 HyperCLOVA 204B?

HyperCLOVA 204B was published by NAVER, based in Korea (Republic of), categorised as industry.

04

When was HyperCLOVA 204B released?

HyperCLOVA 204B was published in September 2021. 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 HyperCLOVA 204B used for?

HyperCLOVA 204B works in Language, and is recorded as handling language modeling/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.

06

How much compute was used to train HyperCLOVA 204B?

Around 2 × 10²³ FLOP, on NVIDIA A100. 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 HyperCLOVA 204B?

None. HyperCLOVA 204B 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.
