ChatGPT
ChatGPT is a conversational AI assistant built by OpenAI that enables users to interact with a powerful language model via natural language, asking questions, giving instructions, brainstorming, translating, coding, summarizing, and more. It integrates tools like web browsing, file uploads, image generation, and supported reasoning models to extend its reach beyond static responses.
Under the hood, ChatGPT is trained through large‑scale datasets and refined using human feedback (a technique known as Reinforcement Learning from Human Feedback, or RLHF), allowing it to better follow instructions and produce coherent, contextually relevant answers. While it is very capable across many domains, it is not infallible: it can sometimes produce plausible but incorrect responses, hallucinations, or biased content, so user oversight is still important.
