Sora 2
OpenAI's flagship video generation model — cinematic realism, synchronized audio, and precise physics simulation up to 12 seconds.
Overview
What is Sora 2
Sora 2 is OpenAI's flagship video generation model, released in September 2025. It creates realistic, cinematic 720p videos up to 12 seconds from text or images, with synchronized dialogue and sound effects. It represents a leap in physical accuracy and controllability over prior models.
Running it privately on Venice
On Venice, Sora 2 runs with anonymized privacy — your prompts are never stored or used for training. This means you can generate videos with confidence that your creative direction remains private and sovereign. The model's full fidelity is accessible without subscription lock-in, paying only per clip.
Assessment
Strengths and limitations
- Exceptional physical realism and accurate simulation of dynamics like buoyancy, rigidity, and motion.
- Synchronized audio generation: includes realistic dialogue, sound effects, and background soundscapes.
- High steerability with strong adherence to complex, multi-shot prompts.
- Supports both text-to-video and image-to-video modes for flexible creative workflows.
- Cinematic quality output suitable for storytelling, advertising, and concept visualization.
- Limited to 720p resolution and clips of 4s, 8s, or 12s — no longer-form video or 4K output.
- Not open-source or self-hostable: access is via API or platforms like Venice.
- No end-to-end encryption or TEE protection on Venice — privacy is anonymized but not fully encrypted.
Samples
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera

Variants
Sora 2 model variants
Sora 2 runs on Venice as 2 variants of the same underlying model. Pick by what you're starting from: a written prompt, a still image, reference images, or an existing clip. Each variant is its own model id on the API; the generation quality is the same across the family.
| Variant | What it is | Clip lengths | Resolutions | Aspect ratios | Audio | Model ID |
|---|---|---|---|---|---|---|
| Text to Videoflagship | Generate a clip from a written prompt | 4s, 8s, 12s | 720p | 16:9, 9:16 | sora-2-text-to-video | |
| Image to Video | Animate a still image into motion | 4s, 8s, 12s | 720p | 16:9, 9:16 | sora-2-image-to-video |
Capability data comes straight from the Venice model API and refreshes with every catalog ingest. The specs and pricing on this page are captured from the flagship variant; pass the model id of the variant you want to the API.

Prompting
Getting better results
Be specific about physics and motion — Sora 2 excels at accurate dynamics like water, cloth, and rigid bodies.
Include audio cues in your prompt (e.g., 'cheering crowd', 'footsteps') to leverage synchronized sound generation.
Use image-to-video mode to animate concept art or product mockups into motion.
Specify aspect ratio in the prompt for optimal framing — 16:9 for landscape, 9:16 for portrait.
