What the numbers mean

Where it came from

Shanhai was published by Unisound, in the country recorded as China, during May 2023. The category the publisher falls under is industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Code generation.

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

Answers

Shanhai — common questions

01

Shanhai— when was it released?

It was published in May 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

02

Shanhai— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering, Code generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

03

Shanhai— what GPU do I need to run it?

None. This 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

Shanhai— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

05

Shanhai— how many parameters does it have?

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

06

Shanhai— who created it?

It was published by Unisound, based in China, an organisation categorised as industry.
