EfficientZero
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
What this model is
EfficientZero was published by Tsinghua University,University of California (UC) Berkeley,Shanghai Qi Zhi institute, in China, in October 2021. It comes out of academia,Academia.
It works in Games, and is recorded as doing atari.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
What went into building it
Around 100,000 tokens went into training it.
Its inclusion criterion is sOTA improvement.
Answers
EfficientZero — common questions
Is EfficientZero open source?
No. EfficientZero has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does EfficientZero have?
No parameter count has been published for EfficientZero, which is why no memory or speed figure appears on this page.
Who created EfficientZero?
EfficientZero was published by Tsinghua University,University of California (UC) Berkeley,Shanghai Qi Zhi institute, based in China, categorised as academia,Academia.
When was EfficientZero released?
EfficientZero was published in October 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.
What is EfficientZero used for?
EfficientZero works in Games, and is recorded as handling atari. 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.
What GPU do I need to run EfficientZero?
None. EfficientZero 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.
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.
