ChatGPT can generate articles, essays, jokes, poetry and job applications in response to text prompts. OpenAI, a private company backed by Microsoft, made it available to the public for free in late November.
OpenAI also developed the AI-powered image generator Dall-E and is at the forefront of generative AI, or technology trained on vast amounts of text and images that can create content from a simple text prompt.
On Thursday, OpenAI announced a $20 monthly subscription, initially for users in the United States only. It would provide a more stable and faster service as well as the opportunity to try new features first, the company said.
Analysts believe the viral launch of ChatGPT will give OpenAI a first-mover advantage against other AI companies. The growing usage, while imposing substantial computing cost on OpenAI, has also provided valuable feedback to help train the chatbot’s responses.
