OpenAI’s Sora video generator goes public after 10-month wait

The release of OpenAI’s Sora video generation model marks a significant advancement in AI-generated video technology, though it enters an increasingly competitive landscape since its initial preview in February.

Launch details and accessibility: OpenAI has made Sora Turbo available to ChatGPT Plus and Pro subscribers through a dedicated website, offering video generation capabilities of up to 20 seconds at 1080p resolution.

• The service launched globally but remains unavailable in Europe
• Initial access has been limited due to heavy traffic, with even existing Plus subscribers facing temporary signup restrictions
• ChatGPT Plus subscribers ($20/month) can create up to 50 videos monthly at 480p resolution, with options for 720p quality
• Pro subscribers ($200/month) receive enhanced capabilities including higher resolution options and longer video durations

Technical capabilities and features: Sora employs innovative approaches to video generation, utilizing visual patches instead of traditional text tokens and incorporating advanced recaptioning techniques.

• The platform processes video generation requests faster than its research version from February 2024
• A new “Explore” interface allows users to browse through other users’ generated videos for inspiration
• The “Storyboard” feature enables frame-by-frame video direction with multiple actions
• The system can create videos in multiple aspect ratios and mix existing assets with AI-generated content

Safety measures and limitations: OpenAI has implemented comprehensive safety protocols while acknowledging current technical constraints.

• The platform restricts videos involving human subjects while refining deepfake prevention systems
• Content involving CSAM and sexual deepfakes is blocked
• All generated videos include C2PA metadata and visible watermarks for identification
• An internal search tool verifies Sora-generated content
• The model currently struggles with physics simulations and complex actions over extended durations

Competitive landscape: While Sora’s release represents a milestone for OpenAI, several competitors have emerged with their own video synthesis models.

• Google’s Veo, Runway’s Gen-3 Alpha, Kling, Minimax, and Hunyuan Video have all entered the market
• These competing platforms have somewhat diminished the initial excitement surrounding Sora’s capabilities

Looking ahead: The current limitations of AI video generation technology highlight both its potential and constraints, as these models excel at transforming existing concepts but struggle with true originality. OpenAI’s planned introduction of specialized pricing tiers in early 2025 suggests a long-term commitment to developing and refining this technology, even as competition in the space intensifies.
