+# LLM
+
+> LLM transform plugin
+
+## Description
+
+Leverage the power of a large language model (LLM) to process data by sending it to the LLM and receiving the
+generated results. Utilize the LLM's capabilities to label, clean, enrich data, perform data inference, and
+more.
+
+## Options
+
+|       name       |  type  | required |               default value                |
+|------------------|--------|----------|--------------------------------------------|
+| model_provider   | enum   | yes      |                                            |
+| output_data_type | enum   | no       | String                                     |
+| prompt           | string | yes      |                                            |
+| model            | string | yes      |                                            |
+| api_key          | string | yes      |                                            |
+| openai.api_path  | string | no       | https://api.openai.com/v1/chat/completions |
+
+### model_provider
+
+The model provider to use. The available options are:
+OPENAI
+
+### output_data_type
+
+The data type of the output data. The available options are:
+STRING,INT,BIGINT,DOUBLE,BOOLEAN.
+Default value is STRING.
+
+### prompt
+
+The prompt to send to the LLM. This parameter defines how LLM will process and return data, eg:
+
+The data read from source is a table like this:
+
+|     name      | age |
+|---------------|-----|
+| Jia Fan       | 20  |
+| Hailin Wang   | 20  |
+| Eric          | 20  |
+| Guangdong Liu | 20  |
+
+The prompt can be:
+
+```
+Determine whether someone is Chinese or American by their name
+```
+
+The result will be:
+
+|     name      | age | llm_output |
+|---------------|-----|------------|
+| Jia Fan       | 20  | Chinese    |
+| Hailin Wang   | 20  | Chinese    |
+| Eric          | 20  | American   |
+| Guangdong Liu | 20  | Chinese    |
+
+### model
+
+The model to use. Different model providers have different models. For example, the OpenAI model can be `gpt-4o-mini`.
+If you use OpenAI model, please refer https://platform.openai.com/docs/models/model-endpoint-compatibility of `/v1/chat/completions` endpoint.
+
+### api_key
+
+The API key to use for the model provider.
+If you use OpenAI model, please refer https://platform.openai.com/docs/api-reference/api-keys of how to get the API key.
+
+### openai.api_path
+
+The API path to use for the OpenAI model provider. In most cases, you do not need to change this configuration. If you are using an API agent's service, you may need to configure it to the agent's API address.
+
+### common options [string]
+
+Transform plugin common parameters, please refer to [Transform Plugin](common-options.md) for details
+
+## Example
+
+Determine the user's country through a LLM.
+
+```hocon
+env {
+  parallelism = 1
+  job.mode = "BATCH"
+}
+
+source {
+  FakeSource {
+    row.num = 5
+    schema = {
+      fields {
+        id = "int"
+        name = "string"
+      }
+    }
+    rows = [
+      {fields = [1, "Jia Fan"], kind = INSERT}
+      {fields = [2, "Hailin Wang"], kind = INSERT}
+      {fields = [3, "Tomas"], kind = INSERT}
+      {fields = [4, "Eric"], kind = INSERT}
+      {fields = [5, "Guangdong Liu"], kind = INSERT}
+    ]
+  }
+}
+
+transform {
+  LLM {
+    model_provider = OPENAI
+    model = gpt-4o-mini
+    api_key = sk-xxx
+    prompt = "Determine whether someone is Chinese or American by their name"
+  }
+}
+
+sink {
+  console {
+  }
+}
+```

+# LLM
+
+> LLM 转换插件
+
+## 描述
+
+利用大型语言模型 (LLM) 的强大功能来处理数据，方法是将数据发送到 LLM 并接收生成的结果。利用 LLM 的功能来标记、清理、丰富数据、执行数据推理等。
+
+## 属性
+
+|        名称        |   类型   | 是否必须 |                    默认值                     |
+|------------------|--------|------|--------------------------------------------|
+| model_provider   | enum   | yes  |                                            |
+| output_data_type | enum   | no   | String                                     |
+| prompt           | string | yes  |                                            |
+| model            | string | yes  |                                            |
+| api_key          | string | yes  |                                            |
+| openai.api_path  | string | no   | https://api.openai.com/v1/chat/completions |
+
+### model_provider
+
+要使用的模型提供者。可用选项为:
+OPENAI
+
+### output_data_type
+
+输出数据的数据类型。可用选项为:
+STRING,INT,BIGINT,DOUBLE,BOOLEAN.
+默认值为 STRING。
+
+### prompt
+
+发送到 LLM 的提示。此参数定义 LLM 将如何处理和返回数据，例如:
+
+从源读取的数据是这样的表格:
+
+|     name      | age |
+|---------------|-----|
+| Jia Fan       | 20  |
+| Hailin Wang   | 20  |
+| Eric          | 20  |
+| Guangdong Liu | 20  |
+
+我们可以使用以下提示:
+
+```
+Determine whether someone is Chinese or American by their name
+```
+
+这将返回:
+
+|     name      | age | llm_output |
+|---------------|-----|------------|
+| Jia Fan       | 20  | Chinese    |
+| Hailin Wang   | 20  | Chinese    |
+| Eric          | 20  | American   |
+| Guangdong Liu | 20  | Chinese    |
+
+### model
+
+要使用的模型。不同的模型提供者有不同的模型。例如，OpenAI 模型可以是 `gpt-4o-mini`。
+如果使用 OpenAI 模型，请参考 https://platform.openai.com/docs/models/model-endpoint-compatibility 文档的`/v1/chat/completions` 端点。
+
+### api_key
+
+用于模型提供者的 API 密钥。
+如果使用 OpenAI 模型，请参考 https://platform.openai.com/docs/api-reference/api-keys 文档的如何获取 API 密钥。
+

+
+source {
+  FakeSource {
+    row.num = 5
+    schema = {
+      fields {
+        id = "int"
+        name = "string"
+      }

+      {fields = [2, "Hailin Wang"], kind = INSERT}
+      {fields = [3, "Tomas"], kind = INSERT}
+      {fields = [4, "Eric"], kind = INSERT}
+      {fields = [5, "Guangdong Liu"], kind = INSERT}
+    ]
+  }
+}
+
+transform {
+  LLM {
+    model_provider = OPENAI
+    model = gpt-4o-mini
+    api_key = sk-xxx
