# OpenAIVideoSora2 - ComfyUI Built-in Node Documentation

> The OpenAIVideoSora2 node generates videos using OpenAI's Sora models.

The OpenAIVideoSora2 node generates videos using OpenAI's Sora models. It creates video content based on a text prompt and an optional input reference image, then delivers the generated video as its output. The node supports different video durations and resolutions depending on the selected model.

**DEPRECATION NOTICE:** OpenAI will stop serving the Sora v2 API in September 2026. This node will be removed from ComfyUI at that time.

## Inputs

| Parameter  | Description                                                                                                                         | Data Type | Required | Range                                                        |
| ---------- | ----------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------------ |
| `model`    | The OpenAI Sora model to use for video generation (default: "sora-2")                                                               | COMBO     | Yes      | "sora-2"<br />"sora-2-pro"                                   |
| `prompt`   | Guiding text; may be empty if an input image is present (default: empty)                                                            | STRING    | Yes      | -                                                            |
| `size`     | The resolution for the generated video (default: "1280x720")                                                                        | COMBO     | Yes      | "720x1280"<br />"1280x720"<br />"1024x1792"<br />"1792x1024" |
| `duration` | The duration of the generated video in seconds (default: 8)                                                                         | COMBO     | Yes      | 4<br />8<br />12                                             |
| `image`    | Optional input reference image used for video generation (fits, character, scene reference, etc.); only a single image is supported | IMAGE     | No       | -                                                            |
| `seed`     | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)                        | INT       | No       | 0 to 2147483647                                              |

**Constraints and Limitations:**

* The "sora-2" model only supports the "720x1280" and "1280x720" resolutions; the "1024x1792" and "1792x1024" options are valid only with the "sora-2-pro" model
* When an image is connected, it must contain exactly one image; connecting more than one image raises an error
* Results are nondeterministic regardless of the seed value

## Outputs

| Output Name | Description                               | Data Type |
| ----------- | ----------------------------------------- | --------- |
| `output`    | The generated video file from OpenAI Sora | VIDEO     |
