Founded in 2015 with high-profile backers such as Elon Musk, Sequoia, and others, OpenAI initially experimented in VR and robotics before pivoting to language models. Their breakthrough, GPT (Generative Pre-trained Transformer), emerged around 2020-2021, transforming AI from experimental tech into a commercial powerhouse. Their mission is to democratize access to artificial general intelligence (AGI), emphasizing scale—believing that larger models will eventually achieve human-like intelligence.
