OpenAI is an artificial intelligence research and deployment company that develops machine learning systems for general-purpose AI applications. Founded in 2015 and headquartered in San Francisco, it states its mission as ensuring that artificial general intelligence benefits all humanity.
Its products and platform include ChatGPT for conversational interactions and text analysis, the OpenAI API Platform for integrating models into applications and workflows, and Sora for text-to-video generation. OpenAI also offers GPTs, the Assistants API, Operator and Codex CLI, and it has introduced Astra for Law for the legal industry.
OpenAI's generative language models, multimodal systems and image creation software are accessible through web interfaces and APIs. They support text generation, software code creation, automated data analysis, image creation and multimodal input handling. Its model line includes the GPT series, GPT-4o, GPT-4 Turbo and GPT-5, with related systems such as DALL·E, CLIP and Voice Engine.
Through its API and platform, OpenAI lets developers, enterprises and researchers build, test and deploy intelligent systems for automation, content generation, data analysis and interactive problem-solving. By 2023, it reported 2 million developers using its API and 92% of Fortune 500 companies using its products to build services.
OpenAI also conducts research into AI safety and operates software infrastructure designed to host and scale digital tools. It was founded as a nonprofit; in 2019 it created a for-profit subsidiary, and under a structure announced on October 28, 2025, the nonprofit is OpenAI Foundation and the for-profit is OpenAI Group PBC, a public benefit corporation controlled by the foundation.
