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.

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

What the numbers mean

What this model is

ChatBit was published by Beijing Institute of Technology,Academy of Military Science,Minzu University of China, in China, in June 2024. academia,Government,Academia is the category the publisher falls under.

It works in Language, and is recorded as doing chat, Language modeling/generation.

It is derived from LLaMA-13B rather than trained from scratch, which is the usual way a specialised model is produced.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

What went into building it

The training set ran to roughly 100,000,000 tokens.

Answers

ChatBit — common questions

01

When was ChatBit released?

ChatBit 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.

02

What is ChatBit used for?

ChatBit works in Language, and is recorded as handling chat, Language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

03

What GPU do I need to run ChatBit?

None. ChatBit 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

Is ChatBit open source?

No. ChatBit has not had its weights published, so it exists only as a service controlled by its owner.

05

How many parameters does ChatBit have?

ChatBit has 13B parameters. Assuming as in LLaMA-13 since it is its finetune. 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.

06

Who created ChatBit?

ChatBit was published by Beijing Institute of Technology,Academy of Military Science,Minzu University of China, based in China, categorised as academia,Government,Academia.

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.
