OpenAI Shows ‘Sora’, an AI Model that Generates Photorealistic Videos

OpenAI, which owns the still-image generator DALL-E, is now in the race to improve the AI video generator. Google and Meta are in this business, too.

OpenAI declined to say how many videos the system learned from or where they came from, except to say the training included both publicly available videos and videos that were licensed from copyright holders. The company says little about the data used to train its technologies, most likely because it wants to maintain an advantage over competitors — and has been sued multiple times for using copyrighted material.

The company is already tagging videos produced by the system with watermarks that identify them as being generated by AI. But it acknowledges that these can be removed.

DALL-E, Midjourney, and other still-image generators have improved so quickly that they are now producing images nearly indistinguishable from photographs. Many digital artists are complaining that it has made it harder for them to find work.

Examples:

An AI-generated video by OpenAI was created with the following prompt: “Several giant wooly mammoths approach treading through a snowy meadow, their long wooly fur lightly blows in the wind as they walk, snow covered trees and dramatic snow capped mountains in the distance, mid afternoon light with wispy clouds and a sun high in the distance creates a warm glow, the low camera view is stunning capturing the large furry mammal with beautiful photography, depth of field.”

This video’s AI prompt: “Beautiful, snowy Tokyo city is bustling. The camera moves through the bustling city street, following several people enjoying the beautiful snowy weather and shopping at nearby stalls. Gorgeous sakura petals are flying through the wind along with snowflakes.”

“Animated scene features a close-up of a short fluffy monster kneeling beside a melting red candle. The art style is 3D and realistic, with a focus on lighting and texture. The mood of the painting is one of wonder and curiosity, as the monster gazes at the flame with wide eyes and open mouth. Its pose and expression convey a sense of innocence and playfulness, as if it is exploring the world around it for the first time. The use of warm colors and dramatic lighting further enhances the cozy atmosphere of the image.”

This video’s AI prompt: “A gorgeously rendered papercraft world of a coral reef, rife with colorful fish and sea creatures.”
