ChatGPT

ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released on November 30, 2022. It relies on large language models from the GPT series, initially fine-tuned from GPT-3.5 using reinforcement learning from human feedback to generate contextually relevant, dialogue-oriented responses. Subsequent versions incorporate advanced models such as GPT-4 and the GPT-5 series, enabling multimodal capabilities including image analysis and code generation. The launch spurred explosive growth in generative AI adoption, reaching 800 million weekly active users by late 2025 and integrating into sectors like programming, writing, research, and education, where it outperforms prior systems on reasoning and knowledge benchmarks. Despite these capabilities, ChatGPT exhibits limitations such as hallucinations—producing confident but fabricated information—and biases from training data imbalances, raising concerns over misinformation, privacy, copyright in training data, and broader societal risks that have intensified regulatory and ethical debates.
