Which startup developed the AI chatbot ChatGPT?

OpenAI developed the AI chatbot ChatGPT.

OpenAI introduced ChatGPT as a research preview on November 30, 2022. The conversational system was built on OpenAI’s generative pre-trained transformer technology, allowing it to produce responses to prompts and continue multi-turn exchanges. Its dialogue format made advanced language-model capabilities accessible through a simple chat interface.

ChatGPT grew out of OpenAI’s GPT research, including models trained to predict and generate language. OpenAI was founded in 2015 as an artificial-intelligence research organization by a group that included Sam Altman, Greg Brockman, Ilya Sutskever, and Elon Musk. The organization later developed products and model families such as GPT, DALL-E, and Sora.

A frequent mix-up is crediting Microsoft, Google, or Meta. Microsoft has invested heavily in OpenAI and integrates OpenAI technology into some products, but it did not develop ChatGPT. Google and Meta operate their own AI programs and models. ChatGPT’s developer and originating organization is OpenAI, even though the service runs on large-scale computing infrastructure and has commercial partnerships.
