OpenAI is an American artificial intelligence research organization headquartered in San Francisco that develops advanced AI systems with the stated mission of creating "safe and beneficial" artificial general intelligence—defined as highly autonomous systems that outperform humans at most economically valuable work. Founded in 2015 as a nonprofit research lab, OpenAI restructured into a capped-profit company to attract necessary funding for developing cutting-edge AI models.

The organization leads the ongoing AI boom through groundbreaking products including ChatGPT, the conversational AI assistant that brought large language models into mainstream consciousness, the GPT family of foundation models powering applications worldwide, DALL-E for image generation, Sora for text-to-video creation, and enterprise API services enabling developers to integrate OpenAI's capabilities into their own applications.

OpenAI's journey from idealistic research lab to AI industry titan illustrates the rapid transformation of artificial intelligence from academic pursuit to commercial powerhouse.

The organization launched in December 2015 with a $1 billion pledge from prominent technology leaders including Elon Musk, Reid Hoffman, Peter Thiel, and Sam Altman. The founders established OpenAI as a nonprofit research laboratory with the ambitious goal of developing artificial general intelligence that benefits all humanity. Early research focused on reinforcement learning, robotics, and natural language processing.

In 2019, OpenAI restructured from pure nonprofit to a hybrid "capped-profit" model creating OpenAI LP, a for-profit entity controlled by the nonprofit OpenAI Foundation. This unusual structure limits investor returns to 100 times their investment, with excess profits flowing to the nonprofit's mission. The restructuring enabled OpenAI to raise the billions necessary for training increasingly large AI models.

Microsoft invested $1 billion in 2019, establishing a strategic partnership providing OpenAI with Azure cloud computing infrastructure essential for training massive models. This partnership deepened substantially, with Microsoft investing nearly $14 billion total across multiple funding rounds through 2025.

The company released GPT-2 in February 2019, gaining attention for human-like text generation capabilities. GPT-3 followed in June 2020 with 175 billion parameters, representing a quantum leap in language model sophistication. November 2022 marked the inflection point when OpenAI publicly launched ChatGPT, achieving unprecedented viral growth reaching 1 million users in five days and 100 million users in two months—faster than any consumer technology in history. ChatGPT's accessible interface demonstrated AI capabilities to mainstream audiences, sparking global fascination with generative AI and triggering massive investment across the industry.
