What is Sora 2? From basic introduction to invitation codes and latest news

• Sora 2 is the latest AI video generation model launched by OpenAI. It can automatically generate high-quality, sound effects and narrative videos based on the text or images input by the user. It continues the core technology of the first generation Sora, and has been fully upgraded in terms of picture stability, physical simulation and detail restoration, becoming OpenAI's flagship image and audio generation model.
• OpenAI CEO Sam Altman said that the vision of Sora 2 is to "enable everyone to create movies with a sentence." Just enter text or image prompts, and Sora 2 can instantly generate realistic and synchronously dubbed videos, making AI creation easier than ever.

• Longer video length: free users can generate 15-second videos, paid versions up to 25 seconds.
• The picture is more realistic: character movements, light and shadow changes, and camera movement are more natural and coherent.
• Supports Remix function: you can extend other people's videos and change characters or scenes.
• Socially interactive: users can share their works and browse videos of other creators.

These features make Sora 2 one of the most creative AI video apps.

The official App "Sora by OpenAI" has been released on the App Store. Its main functions are as follows:

1. Download the App and log in to your OpenAI account This App currently only supports iOS 18.0 and above. It supports Traditional Chinese, Simplified Chinese, English, Japanese, Korean and other languages. It is suitable for those over 13 years old and can be downloaded and used for free.
2. Enter text or upload an image as a prompt word Style commands such as "cinematic lighting" or "slow motion" can be added. In addition, the more specific the prompt word (including action, scene, lens and atmosphere), the more natural the generated effect is usually, for example: "A young woman walking through a futuristic city at sunset."
3. Set video parameters Choose aspect ratio (16:9 or 9:16), video length, style and resolution.
4. Generate and preview videos Videos are automatically generated and can be downloaded, shared or regenerated.
5. Using Cameo character generation After clicking the "Cameo" function, upload a short video and voice, and AI will automatically create a personalized character model. You can then choose whether to include the character in any video, and you can also authorize friends to use it together. Official emphasis: Cameo is only used for content explicitly authorized by the user, and can be revoked or deleted at any time.

Many Taiwanese users are concerned: "Can Sora 2 be used in Taiwan? Is there an invitation code?" According to the official OpenAI support document, Sora 2 and Sora App are not yet fully open in Taiwan.

The official page clearly states: "We are launching preliminary implementation in the United States and Canada today, and are expected to quickly open it to other countries/regions in the future."

This means that currently only users in the United States and Canada can download and log in to the Sora App. Asia (including Taiwan) is still waiting for the opening stage, and the official launch timetable has not yet been announced. If you try to search or download from the Taiwan App Store, you may see a "Region Restrictions" prompt or Sora 2 cannot be found.

As for the invitation code, OpenAI has not yet publicly provided or accepted general applications. It is currently only open to internal testing and invited users. Sora 2’s Cameo feature is also temporarily only enabled in open areas. This feature involves face and voice data authorization, so Taiwanese users cannot enable or create personal Cameo models before passing local regulatory review.

💡 If you want to experience similar AI video generation effects first, you can use the GenApe AI video generation platform first. It also supports video generation and multi-style video creation, and can be used directly in Taiwan without an invitation code or VPN.

Since Sora 2 may not yet be fully available in some regions, here’s a “ready-to-use” alternative so you can start creating videos without waiting.
