Closed weights Zhijiang Lab 70B parameters October 2024

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.

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

AstroOne was published by Zhijiang Lab, in China, in October 2024.

It works in Astronomy.

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

Answers

AstroOne — common questions

01

Is AstroOne open source?

The licensing for AstroOne was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does AstroOne have?

AstroOne has 70B parameters. "Currently, AstroOne, boasting 70 billion parameters and 32 billion tokens of astronomical text corpus, has been evaluated by 10,000 astronomy assessment datasets.". 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 AstroOne?

AstroOne was published by Zhijiang Lab, based in China.

04

When was AstroOne released?

AstroOne was published in October 2024. 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 AstroOne used for?

AstroOne works in Astronomy. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

What GPU do I need to run AstroOne?

None. AstroOne 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.

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.
