## Model Introduction
The 7B models released by Hunyuan this time: [Hunyuan-7B-Pretrain](https://huggingface.co/tencent/Hunyuan-7B-Pretrain) and [Hunyuan-7B-Instruct](https://huggingface.co/tencent/Hunyuan-7B-Instruct) , use better data allocation and training, have strong performance, and have achieved a good balance between computing and performance. It stands out from many large-scale language models and is currently one of the strongest Chinese 7B Dense models.
### Introduction to Technical Advantages
#### Model
- Extended long text capability to 256K and utilizes Grouped Query Attention (GQA)
#### Inference Framework
- This open-source release offers two inference backend options tailored for the Hunyuan-7B model: the popular [vLLM-backend](https://github.com/quinnrong94/vllm/tree/dev_hunyuan) and the TensorRT-LLM Backend. In this release, we are initially open-sourcing the vLLM solution, with plans to release the TRT-LLM solution in the near future.
#### Training Framework
- The Hunyuan-7B open-source model is fully compatible with the Hugging Face format, enabling researchers and developers to perform model fine-tuning using the hf-deepspeed framework. Learn more : [Tencent-Hunyuan-Large](https://github.com/Tencent/Tencent-Hunyuan-Large) 。
