# Mobius RWKV 12B v4 version
Good at Writing and role play, can do some rag.

# Mobius Chat 12B 128K

## Introduction

Mobius is a RWKV v5.2 arch model, a state based RNN+CNN+Transformer Mixed language model pretrained on a certain amount of data.
In comparison with the previous released Mobius, the improvements include:

* Only 24G Vram to run this model locally with fp16;
* Significant performance improvement;
* Multilingual support ;
* Stable support of 128K context length.
* Base model [Mobius-mega-12B-128k-base](https://huggingface.co/TimeMobius/Moibus-mega-12B-128k-base)
  

## Usage
We encourage you use few shots to use this model, Desipte Directly use User: xxxx\n\nAssistant: xxx\n\n is really good too, Can boost all potential ability. 

Recommend Temp and topp: 0.7 0.6/1 0.3/1.5 0.3/0.2 0.8

## More details
Mobius 12B 128k based on RWKV v5.2 arch, which is leading state based RNN+CNN+Transformer Mixed large language model which focus opensouce community
* 10~100 trainning/inference cost reduce;
* state based,selected memory, which mean good at grok;
* community support.

## requirements
24G vram to run fp16, 12G for int8, 6G for nf4 with Ai00 server.

* [RWKV Runner](https://github.com/josStorer/RWKV-Runner)
* [Ai00 server](https://github.com/cgisky1980/ai00_rwkv_server)

## future plan
go bigger and v6
