Initializes a new instance of the [HuggingFaceEmbeddingGenerationService](https://docs.wisej.com/ai/components/api/services/iembeddinggenerationservice/wisej.ai.services.huggingfaceembeddinggenerationservice) class with an optional URL.

| Name    | Type                                                          | Description                                              |
| ------- | ------------------------------------------------------------- | -------------------------------------------------------- |
| **url** | [String](https://docs.microsoft.com/dotnet/api/system.string) | The base URL of the Hugging Face API. Default is `null`. |

[Int32](https://docs.microsoft.com/dotnet/api/system.int32): Gets or sets the maximum size of the array that can be processed in a single request. (Default: `100`)

[String](https://docs.microsoft.com/dotnet/api/system.string): Gets or sets the base URL of the Hugging Face API. (Default: `null`)

[Int32](https://docs.microsoft.com/dotnet/api/system.int32): Gets or sets the size of the vector for the embeddings. This property is not used. (Default: `0`)

## Methods

Asynchronously generates embeddings for the provided text chunks.

| Parameter  | Type                                                              | Description                                         |
| ---------- | ----------------------------------------------------------------- | --------------------------------------------------- |
| **chunks** | [String\[\]](https://docs.microsoft.com/dotnet/api/system.string) | An array of text chunks to generate embeddings for. |

**Returns:** [Task\<Embedding>](https://docs.microsoft.com/dotnet/api/system.threading.tasks.task-1). A task that represents the asynchronous operation. The task result contains the generated [Embedding](https://docs.wisej.com/ai/components/api/embeddings/wisej.ai.embeddings.embedding).

This method handles chunking of input data and parallelizes requests if necessary. It combines results from multiple requests if the input exceeds the maximum array size.

```csharp

var service = new HuggingFaceEmbeddingGenerationService("http://api.example.com");
var embedding = await service.EmbedAsync(new string[] { "text1", "text2" });

```
