The tool can also complete a scene and extend existing videos by filling in missing frames. Rohan Sahai, Sora's product lead, said a team of about five or six engineers built the video generator ...
The Microsoft-backed company, which kicked off a generative AI craze with the launch of its ChatGPT chatbot in November 2022, aims to target similar text-to-video tools from Meta and Alphabet's ...
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. [1] [2]
OpenAI said it is working to build tools that can detect when a video is generated by Sora, and plans to embed metadata, which would mark the origin of a video, into such content if the model is ...
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.

A text-to-video model is a machine learning model that uses a natural language description as input to produce a video relevant to the input text. [20] Advancements during the 2020s in the generation of high-quality, text-conditioned videos have largely been driven by the development of video diffusion models. [21]
The termination of Altman followed by his almost immediate rehiring exposed a deep governance rift between OpenAI’s nonprofit origin and the for-profit model backed by large shareholder Microsoft.
