## 模型概述
|
|||
|
|
|
|||
|
|
> <span style="color:#FF9900;font-size:18px"> 本模型已升级，请使用精度更高的最新版本，原版本归档至 tag v1.0.0。 <br/>更多精度详情，请关注 Benchmark 部分数据。</span>

|
|
通义千问2.5-7B-Instruct-INT4-W4A16 是一个基于 通义千问2.5-7B-Instruct 的 INT4 量化校准模型。
|
|||
|
|
|
|||
|
|
- **模型名称:** Qwen2.5-7B-Instruct-Int4-W4A16
|
|||
|
|
- **模型架构:** Qwen2.5
|
|||
|
|
- **权重量化:** INT4
|
|||
|
|
|
|||
|
|
该模型通过将 [Qwen2.5-7B-Instruct](https://www.modelscope.cn/models/qwen/Qwen2.5-7B-Instruct) 的权重量化为 INT4 数据类型而实现。
|
|||
|
|
|
|||
|
|
量化过程将每个参数从 16bit 减少到 4bit，将模型占用磁盘空间大小，以及推理时加载模型需要的GPU显存空间，减少到了大约为原模型的1/4。量化过程中，只有 transformer 中的 Linear 层权重是量化的，其他层均保持为原模型数据类型，采用混合精度的计算方式，尽可能减少模型量化后所带来的精度损失。
|
|||
|
|
在量化过程中，使用了[AutoGPTQ](https://github.com/AutoGPTQ/AutoGPTQ)，采用 Symmetric group-wise 方式量化（group size : 128）。并在量化过程中，进行了数据校准，以提升模型生成精度，修复 gptq-int4 模型出现乱吐字和无限循环的问题。
|
|||
|
|
|
|||
|
|
> <span style="color: red;">注意：本模型需要 compute capability > 8.0（Ampere、Ada Lovelace、Hopper 架构）的 Nvidia GPU 来支持 INT4 **混合精度**计算。</span>

|
## 部署推理
|
|||
|
|
|
|||
|
|
#### 推荐使用 vLLM
|
|||
|
|
|
|||
|
|
Openai api 兼容模式
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
>>> vllm serve "/home/gavin/llm/Qwen2.5-7B-Instruct-Int4-W4A16" --host 0.0.0.0 --port 8000 --gpu-memory-utilization 0.9 --served-model-name "Qwen2.5-7B-Instruct-Int4-W4A16"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Benchmark
|
|||
|
|
|
|||
|
|
_仅 Linear layer 量化为 INT4 数据类型，其他层保持为原模型数据类型，采用混合精度计算的方式，以及通过综合校准数据集，有助于提升量化后模型的精度表现。_
|
|||
|
|
|
|||
|
|
<span style="color:#FF9900;">本模型的最新版本对精度进行了更广泛的强化提升。</span>
