OpenAI is the lab that turned a research demo into a product the whole world uses. Founded in 2015 and propelled by the launch of ChatGPT, it built the broadest, most polished model line in the market and the most mature developer platform to build on top of it.
The house style is generalist. GPT models are fluent across text, vision, image, audio, and tool use, and the surrounding platform, from function calling to structured outputs to the batch API, is where much of the ecosystem lives. That breadth is the reason OpenAI is most teams’ first stop.
