OpenAI, a leader in artificial intelligence research, has entered the realm of video generation with the unveiling of Sora, its latest GenAI model. Sora is designed to create videos from text descriptions or still images, boasting the ability to generate 1080p movie-like scenes with multiple characters, various types of motion, and detailed backgrounds.
According to OpenAI, Sora can extend existing video clips by filling in missing details, showcasing its versatility in video creation. The model is said to have a deep understanding of language, accurately interpreting prompts to generate compelling characters that express vibrant emotions.
OpenAI emphasizes that Sora not only understands user prompts but also comprehends how those elements exist in the physical world.
While OpenAI’s demo page for Sora exudes confidence, acknowledging some bombast, the cherry-picked samples from the model are impressive, particularly when compared to other text-to-video technologies. Sora can generate videos in different styles (photorealistic, animated, black and white, etc.) lasting up to a minute, a notable improvement over most text-to-video models.
These videos maintain coherence, avoiding common pitfalls like “AI weirdness,” where objects move in physically impossible directions.
Sora Capabilities
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.
Prompt: Drone view of waves crashing against the rugged cliffs along Big Sur’s garay point beach. The crashing blue waters create white-tipped waves, while the golden light of the setting sun illuminates the rocky shore. A small island with a lighthouse sits in the distance, and green shrubbery covers the cliff’s edge. The steep drop from the road down to the beach is a dramatic feat, with the cliff’s edges jutting out over the sea. This is a view that captures the raw beauty of the coast and the rugged landscape of the Pacific Coast Highway.
Prompt: 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.
Sora Safety
However, OpenAI admits that Sora is not perfect, pointing out potential challenges such as struggling with accurately simulating the physics of complex scenes and difficulties in understanding specific instances of cause and effect. The model may also have spatial detail confusion and struggle with precise descriptions of events over time.
Prompt: Five gray wolf pups frolicking and chasing each other around a remote gravel road, surrounded by grass. The pups run and leap, chasing each other, and nipping at each other, playing.Prompt: Five gray wolf pups frolicking and chasing each other around a remote gravel road, surrounded by grass.

Weakness: Animals or people can spontaneously appear, especially in scenes containing many entities.
Positioning Sora as a research preview, OpenAI refrains from making it generally available due to concerns about potential misuse. The company is actively working with experts to identify exploits and is developing tools to detect whether a video was generated by Sora. OpenAI emphasizes its commitment to engaging with policymakers, educators, and artists worldwide to understand concerns and identify positive use cases for this innovative technology.
Despite extensive research and testing, OpenAI acknowledges that it cannot predict all the beneficial ways people will use Sora or all the potential abuses. The company emphasizes the importance of learning from real-world use to continuously improve the safety of AI systems over time.
