Index-1.9B
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
Index-1.9B was published by Shanghai Kuanyu Digital Technology Co., Ltd. (Bilibili), in China, in June 2024. The organisation is categorised as industry.
It works in Language, and is recorded as doing language modeling/generation, Translation, Text summarization, Question answering.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Index-1.9B — common questions
Who created Index-1.9B?
Index-1.9B was published by Shanghai Kuanyu Digital Technology Co., Ltd. (Bilibili), based in China, categorised as industry.
When was Index-1.9B released?
Index-1.9B was published in June 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.
What is Index-1.9B used for?
Index-1.9B works in Language, and is recorded as handling language modeling/generation, Translation, Text summarization, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
What GPU do I need to run Index-1.9B?
None. Index-1.9B 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 Index-1.9B open source?
The licensing for Index-1.9B was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does Index-1.9B have?
Index-1.9B has 1.9B parameters. 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.
