+# OpenAIUpload
+
+## Description
+Represents a multipart file upload object in OpenAI. The Upload object allows you to upload large files (up to 8 GB) by breaking them into multiple parts.
+
+## Properties
+
+| Property | Type | Description |
+| -------- | ---- | ----------- |
+| `id` | Text | The Upload unique identifier, which can be referenced in API endpoints. |
+| `object` | Text | The object type, which is always "upload". |
+| `bytes` | Integer | The intended number of bytes to be uploaded. |
+| `created_at` | Integer | The Unix timestamp (in seconds) for when the Upload was created. |
+| `filename` | Text | The name of the file to be uploaded. |
+| `purpose` | Text | The intended purpose of the file. Possible values: `assistants`, `batch`, `fine-tune`, `vision`, `user_data`. |
+| `status` | Text | The status of the Upload. Possible values: `pending`, `completed`, `cancelled`, `expired`. |
+| `expires_at` | Integer | The Unix timestamp (in seconds) for when the Upload will expire. |
+| `file` | cs.AIKit.OpenAIFile | The ready File object after the Upload is completed. Only present when status is "completed". |
+| `mime_type` | Text | The MIME type of the file (e.g., "text/jsonl", "image/png", "application/pdf"). Could be returned empty by API.|
+
+## Constructor
+
+```4d
+$upload:=cs.AIKit.OpenAIUpload.new($object)
+```
+
+**Parameters:**
+- `$object` (Object): Object containing upload properties
+
+**Note:** This class is typically instantiated by the API response, not manually by users.
+
+## Example
+
+```4d
+// After creating and completing an upload
+var $result : cs.AIKit.OpenAIUploadResult
+$result:=$client.uploads.complete($uploadId; $params)
+
+If ($result.success)
+    var $upload : cs.AIKit.OpenAIUpload
+    $upload:=$result.upload
+
+    ALERT("Upload ID: "+$upload.id)
+    ALERT("Status: "+$upload.status)
+    ALERT("Filename: "+$upload.filename)
+
+    If ($upload.status="completed") && ($upload.file#Null)
+        ALERT("File ID: "+$upload.file.id)
+        ALERT("File ready for use!")
+    End if 
+End if
