Discover what Sora AI is, how OpenAI's revolutionary text-to-video generator works, its key features, pricing, and how to start creating stunning AI videos today.

What is Sora AI?

Sora is OpenAI's groundbreaking AI video generation model that transforms text prompts into high-quality, realistic videos. Think of it as ChatGPT, but for video—you describe what you want to see, and Sora brings it to life.

Launched in preview in February 2024 and officially released as Sora 2 in September 2025, Sora represents a massive leap in AI capabilities—what OpenAI calls the "GPT-3.5 moment" for video generation.

How Does Sora Work?

Sora uses a diffusion transformer model trained on millions of videos to understand how the physical world moves, interacts, and looks. Unlike earlier text-to-video tools that produced choppy, unrealistic clips, Sora generates videos with:

Sora's Key Features

1. Text-to-Video Generation

The core feature: describe any scene in natural language, and Sora generates a matching video.

Example prompts:

  • "A golden retriever astronaut floating in a space station, cinematic lighting"
  • "Japanese anime style: two characters talking under fireworks at a festival"
  • "A timelapse of a flower blooming in a desert, photorealistic"

2. Image-to-Video

Upload any image and Sora will animate it. Perfect for:

  • Bringing photos to life
  • Creating videos from AI-generated images (from DALL-E, Midjourney, etc.)
  • Adding motion to product photos

3. Video Extension & Remixing

4. Cameo Feature (Pro Only)

Put yourself or friends into any video! Upload a photo and Sora can generate videos featuring that person in any scenario.

5. Integrated Audio

Unlike competitors, Sora automatically generates:

  • Background music matching the mood
  • Sound effects (footsteps, wind, crashes)
  • Dialogue when characters speak
