OpenAI is an artificial intelligence research laboratory founded in 2015 and headquartered in San Francisco. The company develops and deploys large language models and foundation models that power conversational AI applications. Its flagship product, ChatGPT, launched in November 2022 and rapidly became one of the fastest-adopted applications in technology history, reaching 100 million users within two months. OpenAI also offers GPT-4, a more advanced language model, and provides API access to developers through its platform. The company operates in the foundation models category, competing directly with Anthropic, Google DeepMind, and Meta in developing transformer-based large language models. OpenAI's approach emphasizes training increasingly capable models using large datasets and computational resources. Notable applications include content generation, coding assistance, customer service automation, and research support across enterprises and consumer markets. OpenAI has secured substantial funding from diverse sources including Microsoft, which invested $13 billion, making it one of the most heavily funded AI companies. The company's valuation reached $500 billion as of recent funding rounds, reflecting investor confidence in the commercial potential of large language models. The organization transitioned from a non-profit structure to a capped-profit model to facilitate venture capital investment. Growth has accelerated significantly following ChatGPT's release, expanding its user base and enterprise adoption substantially. OpenAI created one of the first large language models to achieve mainstream consumer adoption through ChatGPT, establishing a dominant position in accessible AI applications.
