OpenAI introduces Sora, a cutting-edge video generator, revolutionizing content creation with AI technology.
摘要
OpenAI has developed Sora, an advanced AI model capable of creating high-quality videos based on text prompts. Named after the Japanese word for sky, Sora utilizes diffusion models to generate photorealistic images and videos. While showcasing impressive results, there are concerns regarding object tracking accuracy and potential misuse for spreading misinformation.
统计
OpenAI CEO Sam Altman announced the AI model on Thursday through X (formerly Twitter).
The video creation AI model, called Sora, is trained on videos and images of various durations, resolutions, and aspect ratios.
Sora can create images and videos with near-accuracy on a given subject.
The video clips generated by Sora are photorealistic but show limitations in object tracking.
OpenAI plans to start sharing the model with third-party testers to receive feedback for improvement.
