Yesterday Sora v2 leakAt the time, I originally thought we’d have to wait until next week to see the official version of Sora, but to my surprise, OpenAI released Sora directly earlier—and it’s even bundled right into the ChatGPT Plus and ChatGPT Pro plans. That means there’s no need for a separate subscription or payment; as long as you’re a paying ChatGPT user, you can use it starting now.

OpenAI Sora text-to-video tool is officially launched and available for use starting now.
OpenAI earlier announced on X the official launch of Sora, its text-to-video generation tool, and this isn’t even the version from the original preview—it’s Sora Turbo, which OpenAI says is a significantly faster version.
Since previewing Sora in February, we’ve been building Sora Turbo—a significantly faster version of the model to put in your hands. We’re releasing it today as a standalone product to Plus and Pro users. https://t.co/Ap7ad7HR7X

However, although Sora is not free for everyone to use, it also doesn’t require an additional fee. Currently, users subscribed to ChatGPT Plus and ChatGPT Pro plans can use it directly, and the number and quality of videos that can be generated vary by plan.
Sora uses a credits-based system, and ChatGPT Plus users receive 1,000 credits per month, which can generate 50 videos with 480p resolution priority, or 16 5-second videos at 720p resolution, and they will include a watermark.
ChatGPT Pro offers 10,000 credits per month, allowing you to generate 500 priority videos with a maximum resolution of 1080p and video length of up to 20 seconds. It also supports generating 5 videos simultaneously. More importantly, downloaded videos have no watermark, and you can generate unlimited non-priority videos.
The following appears to be the credits calculation method for the resolution and duration of each Sora video (Source:Reddit):

Another thing to note is that when generating AI videos, it’s not done inside ChatGPT—you need to go into Sora Go to the tool page and log in to your ChatGPT account. Due to the high volume of registrations, OpenAI has temporarily paused accepting Sora registrations. Those who want to use it will have to wait; once it opens, they can register and use it.
