ChatGPT now has 1.2 billion weekly users, according to OpenAI, marking another major milestone for the AI chatbot as its user base continues to grow.
OpenAI shared the figure during its DevDay event on September 29, saying ChatGPT has increased from the 1 billion weekly users milestone it reached in July.
The latest figure represents another significant jump in just a few months.
The rapid growth highlights how ChatGPT has continued to expand beyond its early use as a conversational AI tool, with people using it for tasks ranging from writing and coding to research, education and everyday work.
