OpenAI is launching Sora, its text-to-video AI model, on Monday as part of its 12-day “ship-mas” product release series, as The Verge previously reported it would. It’s available today on Sora.com for ChatGPT subscribers in the US and “most other countries,” and a new model, Sora Turbo. This updated model adds features like generating video from text, animating images, and remixing videos.

With a ChatGPT Plus subscription, OpenAI says you can generate up to 50 priority videos (1,000 credits) at resolutions up to 720p with 5-second durations. The $200 per month ChatGPT Pro subscription that launched last week comes with “unlimited generations” and up to 500 priority videos while bumping the resolution to 1080p and the duration to 20 seconds. The more expensive plan also allows subscribers to download videos without a watermark and perform up to five generations simultaneously.

OpenAI first teased its text-to-video AI model, Sora, in February, and earlier today, Marques Brownlee, aka MKBHD, confirmed the launch with a preview based on his experiences testing Sora so far.

During the livestream, OpenAI showed off Sora’s new “explore” page with a feed of AI-generated videos created by other community members, while highlighting a feature called “storyboards” that let you generate videos based on a sequence of prompts, as well as the ability to turn photos into videos. OpenAI also demonstrated a “remix” tool that lets you tweak Sora’s output with a text prompt, along with a way to “blend” two scenes together.

The release of Sora comes just a week after a group of artists, who claimed to be part of the company’s alpha testing program, leaked the product in protest of being used by OpenAI for what they claim was “unpaid R&D and PR.”
