Frequently asked questions
What is Sora?
Sora is OpenAI's text-to-video model. It can generate up to 20-second clips at up to 1080p from a text prompt, an image, or a remix of an existing video, and is used through sora.com by ChatGPT Plus and Pro subscribers.
How long are Sora videos?
At launch, Sora supported up to 20-second clips at 1080p on the Pro tier. Lower tiers are capped at shorter lengths or lower resolutions, and longer edits are built by stitching multiple generations in the storyboard editor.

Sora itself does not synthesise audio. Pair Sora clips with a TTS model such as OpenAI TTS HD, ElevenLabs Multilingual v2, or a music generator for a complete AV piece.
How is Sora priced?
Access is bundled with ChatGPT Plus (limited) and ChatGPT Pro (larger monthly quota at higher resolution). Enterprise and API pricing vary — see OpenAI's Sora page for current limits.
