OpenAI

OpenAI is a San Francisco-based AI research and deployment company founded in 2015, originally structured as a nonprofit and reorganized in 2019 as a capped-profit entity. It develops and commercializes large language models (GPT series), generative AI applications (ChatGPT, DALL-E, Sora), and AI agents. As of mid-2026, OpenAI has launched GPT-5.6 models (Sol, Terra, Luna) with reported 54% token efficiency improvements on agentic coding tasks. The company operates under increasing regulatory oversight, including U.S. government-mandated cybersecurity reviews of advanced models; GPT-5.6 Sol access is currently restricted to trusted partners at government request. OpenAI remains privately held with a reported valuation around $150–157 billion (late 2024–mid 2026) and is IPO-stage but not yet public. Microsoft is its primary investor and cloud infrastructure partner. The company is perceived as the dominant consumer-facing AI brand globally, though its authority is contested by competitors (Anthropic, Google DeepMind, Meta, Mistral) and complicated by internal governance disputes, transparency concerns, and a widening gap between its 'open' branding and closed model practices.
