<Info>
  Sora 2 is the faster, exploration-oriented version of the Sora 2 architecture. For the highest final output quality, use [Sora 2 Pro](/ai-models/video/sora-2-pro). Both models include integrated audio generation.
</Info>

## Faster exploration with OpenAI physics

Sora 2 is designed for the creative development phase — faster output speeds make it practical to explore multiple directions, test prompt variations, and iterate on a concept before committing to a final production render with Sora 2 Pro.

The underlying Multimodal Diffusion Transformer (MM-DiT) architecture is shared with Sora 2 Pro, meaning physics-aware motion and synchronized audio generation are present in both. The distinction is output polish: Sora 2 may produce slightly less refined textures or rendering stability in complex scenes, but at the speed advantage that makes iteration practical.

## How to use

<Steps>
  <Step title="Open the AI Video Generator">
    Log into ImagineArt and go to the **AI Video Generator**.
  </Step>

  <Step title="Select Sora 2">
    Choose **Sora 2** from the model dropdown.
  </Step>

  <Step title="Write your prompt">
    Describe the scene, camera behavior, audio environment, and motion. Include physics-heavy actions for the strongest results from the physics engine.
  </Step>

  <Step title="Set duration and resolution">
    Choose your clip length (4–20 seconds) based on your needs.
  </Step>

  <Step title="Generate and iterate">
    Use the faster generation speed to explore multiple prompt directions. When you find the right approach, switch to Sora 2 Pro for the final render.
  </Step>
</Steps>

## Prompting tips

* **Use it for direction testing** — Generate 4–6 variations of a scene at lower cost and faster speed to find the best approach before using Sora 2 Pro for the final.
* **Include audio context explicitly** — "The scene opens with rain sounds and distant thunder, building to a dramatic climax" guides the integrated audio generation effectively.
* **Physics descriptions work well** — "A ball rolls down a ramp, bounces off the floor twice, and comes to rest" will produce physically accurate behavior.

### Example prompts

> A father and young daughter walk through a field of sunflowers at golden hour. Wide shot panning slowly right. Gentle wind rustling leaves. Warm, emotional atmosphere. 15 seconds.

> POV shot of a kayaker navigating rapids. Water churning realistically, paddle splashing, rush of the river audible. Exciting and dynamic. 12 seconds.

| [Sora 2 Pro](/ai-models/video/sora-2-pro)         | Standard | Maximum | Yes   | 25s      | Final production output |
| [Google Veo 3.1](/ai-models/video/google-veo-3-1) | Standard | Premium | Yes   | 60s      | Long-form, 4K           |
| [Wan 2.5](/ai-models/video/wan-2-5)               | Standard | High    | Yes   | 10s      | Efficient audio-visual  |

<Tip>
  Use Sora 2 as your creative development model. When you've found the right direction and prompt, switch to [Sora 2 Pro](/ai-models/video/sora-2-pro) for the final-quality render — you'll get better textures, more stable complex scenes, and more refined overall output.
