# Text to Image

> This endpoint allows users to generate images from text prompts.

## Request

Make a `POST` request to below endpoint and pass the required parameters as a request body.

```curl curl theme={null}
--request POST 'https://modelslab.com/api/v1/enterprise/text2img' \
```

<Info>
  To use the **load balancer**, you need to have **more than 1 server**. Pass the first server's API key, and it will handle the load balancing with the other servers.
</Info>

<Check>
  You can also use multi Lora. Just make sure to pass comma saparated lora model ids to the `lora_model` as `"more_details,animie"` in the request body.
</Check>

<Check>
  You can find a list of the public models available and their IDs **[here](https://modelslab.com/models)**.
