What is OpenAI?
OpenAI is an AI research and deployment company founded as a nonprofit in 2015. Today it consists of the nonprofit OpenAI Foundation and the for-profit OpenAI Group, a public benefit corporation controlled by the Foundation. Its public products include ChatGPT, developer APIs, image and video generation, and the open-weight gpt-oss models. OpenAI announced a confidential S-1 on June 8, 2026, but said it had not decided when to go public.
Why — the first-principles explanation
To understand OpenAI, separate the organization from the products people use. OpenAI describes itself as an AI research and deployment company whose mission is to ensure that artificial general intelligence benefits all of humanity. It was founded as a nonprofit in 2015.
Its current structure has two connected parts: the nonprofit OpenAI Foundation and the for-profit OpenAI Group, which operates as a public benefit corporation. The Foundation controls the Group. That distinction matters because "public benefit corporation" describes a legal form and mission obligation; it does not by itself mean the company's shares trade on a public stock exchange.
The products are separate access paths to the research. ChatGPT is the consumer assistant for conversation, work, coding and creation. The OpenAI API is the developer platform for building applications. OpenAI also publishes image-generation and video-generation tools, while gpt-oss is an open-weight model family released under Apache 2.0 for developers who want to run and customize models in their own environments. Features, plans and model availability change, so use the current product or developer documentation for a purchase or build decision.
OpenAI also announced on June 8, 2026 that it had submitted a confidential draft S-1 to the SEC. The announcement said timing was undecided. A confidential filing is an option to pursue a future offering, not evidence that OpenAI stock is already publicly traded.
An example that makes it click
Imagine a research foundation that builds useful technology, then creates a mission-bound operating company to deploy it at global scale. The foundation still holds the governing keys, while the operating company runs products and serves users. ChatGPT is the front door for individuals, the API is the workshop for developers, and gpt-oss is a set of models that developers can take into their own infrastructure. The legal structure, the products and the investment question are related, but they are not the same thing.
How to do it
- Choose ChatGPT when you want a hosted assistant for everyday questions, writing, analysis, coding or image creation.
- Choose the OpenAI API when you are building an application and need programmatic model access; check the current API documentation and pricing.
- Use the image or video documentation for media workflows, and verify model availability and deprecation notices before committing production work.
- Choose gpt-oss when you need open-weight models that can be customized and deployed in your own environment; review the Apache 2.0 license and hardware requirements.
- For investment questions, distinguish OpenAI Group's public-benefit-corporation structure from an exchange listing and verify current SEC or company announcements.

What is OpenAI? It is an AI research and deployment company founded as a nonprofit in 2015. Today it has two connected parts: the nonprofit OpenAI Foundation and OpenAI Group, a for-profit public benefit corporation controlled by that Foundation. For users, the front door is ChatGPT, which helps with conversation, work, coding and creation. Developers can use the OpenAI API to build applications, and OpenAI publishes separate image and video tools. It also released gpt-oss open-weight models under Apache 2.0 for people who want to customize and run models in their own environments. One important distinction: OpenAI announced a confidential S-1 on June 8, 2026, but said timing was undecided. A public benefit corporation is a legal structure, not proof that shares already trade on an exchange. For current limits, prices and availability, check the official product and developer pages.
