Sora 2 Pro
OpenAI's most powerful text-to-video model, delivering up to 25-second cinematic clips with synchronized audio, lifelike physics, and unprecedented creative control.
OpenAI Long-form text-to-video with synchronized audio
Sora 2 Pro is the premium tier of OpenAI's second-generation video generation model, available to ChatGPT Pro subscribers. It generates videos up to 25 seconds in length at resolutions up to 1080p and frame rates between 24 and 60 fps, with synchronized dialogue, sound effects, and ambient audio produced alongside the video. The model also includes a Cameo feature that lets users inject a consistent character — based on an uploaded video of a person, pet, or object — into any generated scene.
Sora 2 Pro is designed for filmmakers, content creators, marketers, and storytellers who require longer, higher-fidelity AI-generated video with professional-grade audio. The model handles complex, multi-part prompts and maintains character and scene continuity across multiple shots within a single clip. It models physical phenomena such as gravity, collisions, and fluid dynamics, and scored approximately 8.5 out of 10 in independent physics evaluations. The model's training data has a cutoff of September 2025.
