# Qwen2-beta-1.8B-Chat-GGUF |
|
|
|
|
|
## Introduction |
|
|
|
Qwen2-beta is the beta version of Qwen2, a transformer-based decoder-only language model pretrained on a large amount of data. In comparison with the previous released Qwen, the improvements include: |
|
|
|
* 6 model sizes, including 0.5B, 1.8B, 4B, 7B, 14B, and 72B; |
|
* Significant performance improvement in human preference for chat models; |
|
* Multilingual support of both base and chat models; |
|
* Stable support of 32K context length for models of all sizes |
|
* No need of `trust_remote_code`. |
|
|
|
For more details, please refer to our blog post and GitHub repo. In this repo, we provide the `q8_0` quantized model in the GGUF format. |

## Model Details |
|
Qwen2 is a language model series including decoder language models of different model sizes. For each size, we release the base language model and the aligned chat model. It is based on the Transformer architecture with SwiGLU activation, attention QKV bias, group query attention, mixture of sliding window attention and full attention, etc. Additionally, we have an improved tokenizer adaptive to multiple natural languages and codes. For the beta version, temporarily we did not include GQA and the mixture of SWA and full attention. |

## Training details |
|
We pretrained the models with a large amount of data, and we post-trained the models with both supervised finetuning and direct preference optimization. However, DPO leads to improvements in human preference evaluation but degradation in benchmark evaluation. In the very near future, we will fix both problems. |

## Requirements |
|
We advise you to clone [`llama.cpp`](https://github.com/ggerganov/llama.cpp) and install it following the official guide. |
|
|
|
|
|
## How to use |
|
Cloning the repo may be inefficient, and thus you can manually download the GGUF file that you need or use `huggingface-cli` (`pip install huggingface_hub`) as shown below: |
|
```shell |
|
huggingface-cli download Qwen/Qwen2-beta-1_8B-Chat-GGUF qwen2-beta-1_8b-chat-q8_0.gguf --local-dir . --local-dir-use-symlinks False |
|
``` |
|
|
|
We demonstrate how to use `llama.cpp` to run Qwen2-beta: |
|
```shell |
|
./main -m qwen2-beta-1_8b-chat-q8_0.gguf -n 512 --color -i -cml -f prompts/chat-with-qwen.txt |
|
``` |
