+# openai_format_embedding
+
+一个兼容 OpenAI Embeddings 接口格式的本地向量服务，基本支持所有 huggingface 能找到的嵌入模型。
+
+## 功能说明
+
+- 提供 `POST /v1/embeddings` 接口
+- 支持单条文本或文本数组输入
+- 返回结构与 OpenAI Embeddings 响应格式一致
+- 可通过环境变量配置模型路径、监听地址、端口和 worker 数
+
+## 环境变量
+
+可参考 [.env.example](.env.example)。
+
+- `EMBEDDING_PATH`：模型目录路径，支持本地路径或 UNC 网络路径
+- `EMBEDDING_HOST`：服务监听地址，默认 `0.0.0.0`
+- `EMBEDDING_PORT`：服务监听端口，默认 `8000`
+- `EMBEDDING_WORKERS`：Uvicorn worker 数，默认 `5`
+
+## 安装依赖
+
+```bash
+pip install -r requirements.txt
+```
+
+## 启动服务
+
+```
+# 编辑 .env 文件，配置 EMBEDDING_PATH 等参数
+cp .env.example .env
+
+# 启动服务
+python main.py
+```
+
+## 调用示例
+
+```bash
+curl -X POST "http://127.0.0.1:8000/v1/embeddings" \
+	-H "Content-Type: application/json" \
+	-d '{
+		"model": "bge-m3",
+		"input": ["hello world", "你好，向量服务"]
+	}'
+```
+
+返回示例（结构示意）：
+
+```json
+{
+	"data": [
+		{
+			"object": "embedding",
+			"embedding": [0.0123, -0.0456],
+			"index": 0
+		}
+	],
+	"model": "bge-m3",
+	"object": "list",
+	"usage": {
+		"prompt_tokens": 2,
+		"total_tokens": 4
+	}
+}
+```
+
+## 说明
+
+- `prompt_tokens` 当前实现按空格分词统计
+- `total_tokens` 使用 `cl100k_base` 编码统计
