ChatGPT is credited with starting the AI boom, which has led to ongoing rapid investment in and public attention to the field of artificial intelligence.[3] By January 2023, it had become what was then the fastest-growing consumer software application in history, gaining over 100 million users and contributing to the growth of OpenAI's current valuation of $86 billion.[4][5] ChatGPT's release spurred the release of competing products, including Gemini, Claude, Llama, Ernie, and Grok.[6] Microsoft launched Copilot, initially based on OpenAI's GPT-4. In June 2024, a partnership between Apple Inc. and OpenAI was announced in which ChatGPT is integrated into the Apple Intelligence feature of Apple operating systems.[7] Some observers raised concern about the potential of ChatGPT and similar programs to displace or atrophy human intelligence, enable plagiarism, or fuel misinformation.[8][9]
ChatGPT is built on OpenAI's proprietary series of generative pre-trained transformer (GPT) models and is fine-tuned for conversational applications using a combination of supervised learning and reinforcement learning from human feedback.[8] ChatGPT was released as a freely available research preview, but due to its popularity, OpenAI now operates the service on a freemium model. Users on its free tier can access GPT-4o and GPT-3.5. The ChatGPT subscriptions "Plus", "Team" and "Enterprise" provide additional features such as DALL-E 3 image generation and increased GPT-4o usage limit.[10]
