Sora is a text-to-video model developed by OpenAI. The model generates short video clips based on user prompts , and can also extend existing short videos. Sora was released publicly for ChatGPT Plus and ChatGPT Pro users in December 2024.
"Sora can help, much like a camera, editing equipment, or great performance," Woodman said in an email. "But without great storytelling and storytellers, it will be just a tool on the shelf.
There are several architectures that have been used to create Text-to-Video models. Similar to Text-to-Image models, these models can be trained using Recurrent Neural Networks (RNNs) such as long short-term memory (LSTM) networks, which has been used for Pixel Transformation Models and Stochastic Video Generation Models, which aid in consistency and realism respectively.

Producing high-quality visual art is a prominent application of generative AI. [65] Generative AI systems trained on sets of images with text captions include Imagen , DALL-E , Midjourney , Adobe Firefly , FLUX.1 , Stable Diffusion and others (see Artificial intelligence art , Generative art , and Synthetic media ).
Sora marks a stunning comeback for a company nearly torn apart by its biggest-ever internal crisis just three months ago. ... in the process eclipsing both Amazon and Alphabet as the world’s ...
Walter Woodman of Shy Kids, the team behind the “Air Head” short made with OpenAI’s Sora, warned, “I think that when people talk about AI, they talk about faster and cheaper. And I think ...
Sora's technology is an adaptation of the technology behind the DALL·E 3 text-to-image model. [238] OpenAI trained the system using publicly-available videos as well as copyrighted videos licensed for that purpose, but did not reveal the number or the exact sources of the videos.
Text-to-video generative models, like Sora, can introduce inaccuracies in generated videos. One example involves the Glenfinnan Viaduct, a famous landmark featured in the Harry Potter film series. Sora mistakenly added a second track to the viaduct railway, resulting in an unrealistic depiction.
