Closed weights Uber AI,OpenAI April 2020

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.

On record

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean

Background

Go-explore was published by Uber AI,OpenAI, in United States of America, in April 2020. The organisation is categorised as industry,Industry.

It works in Games, and is recorded as doing atari.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

How it was trained

Around 40,000,000,000 tokens went into training it.

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

Answers

Go-explore — common questions

01

Who created Go-explore?

Go-explore was published by Uber AI,OpenAI, based in United States of America, categorised as industry,Industry.

02

When was Go-explore released?

Go-explore was published in April 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

03

What is Go-explore used for?

Go-explore works in Games, and is recorded as handling atari. These are the areas it was designed around; they describe intent rather than a hard boundary.

04

What GPU do I need to run Go-explore?

None. Go-explore 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.

05

Is Go-explore open source?

No. Go-explore has not had its weights published, so it exists only as a service controlled by its owner.

06

How many parameters does Go-explore have?

No parameter count has been published for Go-explore, which is why no memory or speed figure appears on this page.

The other direction

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.
