Persia
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
Where it came from
Persia was published by ETH Zurich,Kuaishou Technology, in Switzerland, in November 2021. academia,Industry is the category the publisher falls under.
It works in Recommendation, and is recorded as doing recommender system.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Persia — common questions
Who created Persia?
Persia was published by ETH Zurich,Kuaishou Technology, based in Switzerland, categorised as academia,Industry.
When was Persia released?
Persia was published in November 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 Persia used for?
Persia works in Recommendation, and is recorded as handling recommender system. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
What GPU do I need to run Persia?
None. Persia 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.
Is Persia open source?
No. Persia has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Persia have?
Persia has 100T parameters. 100 trillion. 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.
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.
