OpenAI in the context of "Text-to-video model"

Generative artificial intelligence (Generative AI, or GenAI) is a subfield of artificial intelligence that uses generative models to produce text, images, videos, audio, software code or other forms of data. These models learn the underlying patterns and structures of their training data and use them to produce new data based on the input, which often comes in the form of natural language prompts.

Generative AI tools have become more common since the AI boom in the 2020s. This boom was made possible by improvements in transformer-based deep neural networks, particularly large language models (LLMs). Major tools include chatbots such as ChatGPT, Copilot, Gemini, Claude, Grok, and DeepSeek; text-to-image models such as Stable Diffusion, Midjourney, and DALL-E; and text-to-video models such as Veo and Sora. Technology companies developing generative AI include OpenAI, xAI, Anthropic, Meta AI, Microsoft, Google, Mistral AI, DeepSeek, Baidu and Yandex.

ChatGPT is a generative artificial intelligence chatbot developed by OpenAI, and released in November 2022. It uses a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). OpenAI operates the service on a freemium model. Users can interact with ChatGPT through text, audio, and image prompts.

The service gained 100 million users in two months making it the fastest-growing consumer software application in history. ChatGPT's website is among the top 5 most-visited websites globally, It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work.

An AI boom is a period of rapid growth in the field of artificial intelligence (AI). The current boom is an ongoing period that originally started from 2010 to 2016, but saw increased acceleration in the 2020s. Examples of this include generative AI technologies, such as large language models and AI image generators developed by companies like OpenAI, as well as scientific advances, such as protein folding prediction led by Google DeepMind. This period is sometimes referred to as an AI spring, a term used to differentiate it from previous AI winters. As of 2025, ChatGPT has emerged as the 4th most visited website globally, surpassed only by Google, YouTube, and Facebook.

Microsoft Copilot is a generative artificial intelligence chatbot developed by Microsoft AI, a division of Microsoft. Based on OpenAI's GPT-4 and GPT-5 series of large language models, it was launched in 2023 as Microsoft's main replacement for the discontinued Cortana.

The service was introduced in February 2023 under the name Bing Chat, as a built-in feature for Microsoft Bing and Microsoft Edge. Over the course of 2023, Microsoft began to unify the Copilot branding across its various chatbot products, cementing the "copilot" analogy. At its Build 2023 conference, Microsoft announced its plans to integrate Copilot into Windows 11, allowing users to access it directly through the taskbar. In January 2024, a dedicated Copilot key was announced for Windows keyboards.

Gemini (formerly known as Bard) is a generative artificial intelligence chatbot and virtual assistant developed by Google. Based on the large language model (LLM) of the same name, it was launched on March 21, 2023 in response to the rise of OpenAI's ChatGPT.

Midjourney is a generative artificial intelligence program and service created and hosted by the San Francisco-based "independent research lab" Midjourney, Inc. Midjourney generates images from natural language descriptions, called prompts, similar to OpenAI's DALL-E and Stability AI's Stable Diffusion. It is one of the technologies of the AI boom.

The tool was in open beta as of August 2024, which it entered on July 12, 2022. The Midjourney team is led by David Holz, who co-founded Leap Motion. Holz told The Register in August 2022 that the company was already profitable. Users generate images with Midjourney using Discord bot commands or the official website.

DALL-E, DALL-E 2, and DALL-E 3 (stylised DALL·E) are text-to-image models developed by OpenAI using deep learning methodologies to generate digital images from natural language descriptions known as prompts.

The first version of DALL-E was announced in January 2021. In the following year, its successor DALL-E 2 was released. DALL-E 3 was released natively into ChatGPT for ChatGPT Plus and ChatGPT Enterprise customers in October 2023, with availability via OpenAI's API and "Labs" platform provided in early November. Microsoft implemented the model in Bing's Image Creator tool and plans to implement it into their Designer app. With Bing's Image Creator tool, Microsoft Copilot runs on DALL-E 3. In March 2025, DALL-E-3 was replaced in ChatGPT by GPT Image 1's native image-generation capabilities.

A text-to-video model is a form of generative artificial intelligence that uses a natural language description as input to produce a video relevant to the input text. Advancements during the 2020s in the generation of high-quality, text-conditioned videos have largely been driven by the development of video diffusion models.

Sora is a text-to-video model and social media app developed by OpenAI. The model generates short video clips based on prompts, and can also extend existing short videos. In February 2024, OpenAI previewed examples of its output to the public, with the first generation of Sora released publicly for ChatGPT Plus and ChatGPT Pro users in the US and Canada in December 2024, and the second generation, called Sora 2, was released to select users in the US and Canada at the end of September 2025. It integrates social media features.

By default, the generator uses copyrighted material in its videos (unless copyright holders actively opt-out of having their content included), and videos contain a visible, moving digital watermark to prevent misuse. However, only a week after Sora 2's release, third-party programs became prevalent which could remove the watermark.
