ChatGPT generative AI service

ChatGPT is a revolutionary artificial intelligence chatbot developed by OpenAI. Originally launched in November 2022, it was built on top of the GPT architecture to provide human-like conversational responses. The product is primarily engineered and hosted in the United States, utilizing large-scale data centers located globally for its processing power.

OpenAI operates under a unique structure involving a non-profit parent entity and a capped-profit subsidiary. Since its inception, it has received significant investment from Microsoft, which holds a substantial partnership and license for its technologies. As of 2025 and looking toward 2026, ChatGPT remains the flagship product of OpenAI, maintaining its headquarters in San Francisco, California. The brand has evolved from a research experiment into a global platform used by millions for productivity, coding, and creative tasks.
