Definition
OpenAI is an AI research and product company that develops large language models and generative AI systems, including the GPT model family, ChatGPT, and developer APIs for integrating AI into applications.
Overview
Founded in 2015, OpenAI became one of the most influential organizations in modern AI after releasing ChatGPT in November 2022, a conversational interface built on its GPT (Generative Pre-trained Transformer) models that brought large language models to mainstream consumer use almost overnight. The company's research spans natural language processing, computer vision, and reinforcement learning, and its releases have repeatedly shaped how the wider industry builds AI products. Beyond the consumer ChatGPT product, OpenAI offers a developer platform and API that lets engineers integrate GPT models, image generation, speech-to-text, and embeddings directly into their own applications. This API-first approach — alongside function calling, fine-tuning endpoints, and an assistants framework — has made OpenAI's models a default building block for teams developing AI agents and other generative AI tooling, often orchestrated with frameworks such as LangChain. OpenAI operates under a capped-profit structure overseen by a nonprofit parent, a governance model created to balance commercial growth with its stated mission of ensuring artificial general intelligence benefits humanity broadly. It competes directly with Anthropic, Google DeepMind, and other frontier AI labs, and its models remain widely used both directly and as the backbone of countless third-party products and startups.
