It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. The chatbot has also been criticized for its limitations and potential for unethical use. It has been lauded for its potential to transform numerous professional fields, and has instigated public debate about the nature of creativity and the future of knowledge work. It is credited with aviator download accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI).

• ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site.
• Google’s Bard (now Gemini) launched on February 6, 2023, one day before Microsoft’s announcement of Bing Chat (now Microsoft Copilot).
• Initially leveraging the GPT-3 large language model, which represents the third generation of Generative Pre-trained Transformer, ChatGPT utilizes a neural network machine learning architecture.
• In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.

Additionally, users can access its privacy policy before registration. Italian regulators assert that ChatGPT was exposing minors to age-inappropriate content, and that OpenAI’s use of ChatGPT conversations as training data could violate Europe’s General Data Protection Regulation.

A movement named QuitGPT emerged in February 2026 on Reddit, criticizing OpenAI’s ties with the Trump administration, such as a $25 million donation from OpenAI’s president Greg Brockman and his wife to a Trump Super PAC in 2025.

ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history. In The Atlantic magazine’s “Breakthroughs of the Year” for 2022, Derek Thompson included ChatGPT as part of “the generative-AI eruption” that “may change our mind about how we work, how we think, and what human creativity is”. Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”.
