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.

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

Background

GPT3-6.7B + muP was published by Microsoft,OpenAI, in United States of America, in March 2022. The organisation is categorised as industry,Industry.

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.

How it was trained

Producing it required around 1.3 × 10²² FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Around 300,000,000,000 tokens went into training it.

Answers

GPT3-6.7B + muP — common questions

01

What is GPT3-6.7B + muP used for?

GPT3-6.7B + muP 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.

02

How much compute was used to train GPT3-6.7B + muP?

Around 1.3 × 10²² 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.

03

What GPU do I need to run GPT3-6.7B + muP?

None. GPT3-6.7B + muP 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.

04

Is GPT3-6.7B + muP open source?

No. GPT3-6.7B + muP has not had its weights published, so it exists only as a service controlled by its owner.

05

How many parameters does GPT3-6.7B + muP have?

GPT3-6.7B + muP has 6.7B 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.

06

Who created GPT3-6.7B + muP?

GPT3-6.7B + muP was published by Microsoft,OpenAI, based in United States of America, categorised as industry,Industry.

07

When was GPT3-6.7B + muP released?

GPT3-6.7B + muP was published in March 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.

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.
