Answer
OpenAI has introduced Sora, a new generative AI model capable of creating videos from text instructions. Sora is a diffusion model that uses a transformer architecture, similar to GPT models, to generate realistic and imaginative scenes, including complex scenarios with multiple characters and specific types of motion. The model can also animate still images, extend existing videos, and fill in missing frames, producing videos up to a minute long in various styles such as photorealistic, animated, or black and white. Despite its capabilities, Sora has limitations, such as difficulties in simulating complex physics, understanding cause and effect, and maintaining spatial details accurately. For instance, it might not show a bite mark on a cookie after someone takes a bite, or it could mix up left and right in a scene. OpenAI is taking safety precautions before making Sora widely available. They are working with red teamers to test the model for potential harms, such as misinformation, hateful content, and bias. They are also developing tools to detect misleading content and plan to include C2PA metadata in the future to ensure the provenance of videos generated by Sora. Sora is currently available to red teamers and a select group of visual artists, designers, and filmmakers for feedback. OpenAI is engaging with policymakers, educators, and artists to understand concerns and identify positive use cases for the technology. They emphasize that learning from real-world use is crucial for creating and releasing increasingly safe AI systems. The introduction of Sora follows OpenAI's pattern of rapid development in generative AI tools, including ChatGPT, DALL-E 3, and now Sora, which represents a significant advancement in AI's ability to generate video content.
