About OpenAI
OpenAI is the company behind ChatGPT, GPT-4, and DALL-E — the products that ignited the generative AI revolution. Founded in 2015 as a non-profit AI research lab by Sam Altman, Elon Musk, and others, OpenAI restructured as a capped-profit company in 2019 to attract the capital needed to pursue artificial general intelligence (AGI).
ChatGPT's launch in November 2022 was the fastest consumer technology adoption in history, reaching 100 million users in two months. The product demonstrated that large language models could be useful, accessible, and engaging for mainstream users — not just researchers. This single launch catalyzed over $100 billion in AI investment and forced every major technology company to accelerate its AI strategy.
OpenAI operates as both a research lab and a product company. Its API serves as the foundation for thousands of AI applications, while ChatGPT (free and Plus) serves consumers directly. The company has raised over $11 billion, primarily from Microsoft, which has invested $13 billion and integrated OpenAI's models across its product suite. OpenAI's revenue reportedly exceeded $2 billion annualized in 2024, driven by API usage and ChatGPT subscriptions.
Technology & Approach
OpenAI's technical approach centers on scaling transformer-based language models. GPT-4, its flagship model, is believed to use a Mixture of Experts (MoE) architecture with over 1 trillion parameters. The company pioneered reinforcement learning from human feedback (RLHF) for aligning models with human preferences. For image generation, OpenAI developed DALL-E using diffusion models, and for code, Codex powers GitHub Copilot. OpenAI's research spans multimodal AI (GPT-4V, GPT-4o), reasoning (o1 series), and agent capabilities.
