Sora 2 is OpenAI’s text-to-video model, generating realistic clips with synchronized dialogue and sound effects – a genuine step up in world simulation. Since the Sora 2 launch it has been open to everyone through the social Sora app, where free users generate within daily compute limits and every clip is remixable.
ChatGPT Plus at $20 per month adds meaningful headroom and higher quality, while Sora 2 Pro – the watermark-free, highest-fidelity tier – comes bundled with ChatGPT Pro plans from $100 per month. The API bills per second (about $0.10 per second for 720p standard), which works out to roughly $1 for a 10-second clip.
