OpenAI is the company behind ChatGPT and the GPT model family. Founded in 2015, they've built the most widely-used AI models in the world. GPT set the standard for large language model capability, and their continued model releases push the frontier of what AI can do. OpenAI models excel at general-purpose tasks, creative writing, and following complex instructions.
