OpenAI Launches Sora AI Video Model
OpenAI has officially launched Sora, its new artificial intelligence (AI) video generation model. The announcement came on Monday, marking a significant milestone for the company. Sora was first previewed in February to a select group of individuals. Now, it is available to the public in a variant called Sora Turbo. This innovative model can generate videos in 1080p resolution, with a maximum length of 20 seconds. Currently, Sora is accessible through a standalone website, but only to paid subscribers of ChatGPT.
Features and Capabilities of Sora
Sora offers a range of exciting features for users interested in video creation. The model can generate videos in various aspect ratios, including widescreen, vertical, and square formats. Users can also upload their own videos and images, allowing for a more personalized touch. This flexibility enables users to remix and blend their content with AI-generated videos. One of the standout features of Sora is its ability to create videos from scratch using simple text prompts. This opens up new possibilities for content creators, marketers, and educators.
Additionally, Sora includes a storyboard interface. This tool allows users to set specific inputs for each frame of the video, giving them greater control over the final product. The AI model operates as a diffusion model, which means it can foresee multiple frames at once. This capability helps maintain consistency throughout the 20-second video duration. OpenAI has also integrated a transformer architecture and recaptioning techniques from DALL-E 3, enhancing the model’s performance and output quality.
Subscription Plans and Limitations
Access to Sora is currently limited to ChatGPT Plus and Pro subscribers. Those without a subscription cannot create a new account on the platform. Plus users can generate up to 50 videos at 480p resolution each month, or fewer videos at 720p. For those opting for the ChatGPT Pro subscription, priced at $200 per month, the benefits are significantly enhanced. Pro users can enjoy “10x more usage,” along with higher resolutions and longer video durations. However, OpenAI has not specified the exact limits for these features.
Despite its advanced capabilities, Sora comes with certain restrictions. At launch, the number of uploads will be limited, and users must adhere to specified rate limits. This approach aims to manage server load and ensure a smooth user experience. The company has designed Sora with safety in mind, implementing measures to prevent the generation of harmful content. This includes blocking videos that depict child sexual abuse and sexual deepfakes. OpenAI is committed to maintaining a responsible AI environment while providing innovative tools for creativity.
Data Sources and Safety Measures
OpenAI has taken significant steps to ensure the quality and safety of the data used to train Sora. The company sourced a diverse range of data from the public domain, leveraging partnerships and collaborations. This data was collected from machine learning datasets and web crawls. Additionally, OpenAI collaborated with Shutterstock and Pond5 to create proprietary datasets specifically for Sora.
To further enhance the model’s safety, OpenAI has implemented visible watermarks and metadata in compliance with the standards set by the Coalition for Content Provenance and Authenticity (C2PA). These measures aim to minimize the risks associated with realistic AI video generation. The company has also added protections for media uploads that include identifiable individuals. By prioritizing safety and ethical considerations, OpenAI aims to foster a responsible approach to AI technology.
