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

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
• Ai00 server

future plan

go bigger and v6
