Definition

ChatGPT is OpenAI's flagship product. While it started as a simple chatbot, it has evolved into a multimodal platform that can see, hear, speak, and analyze data. It is powered by a Large Language Model (LLM).

Its biggest differentiator today is Reasoning. Building on the "Chain of Thought" capabilities introduced in earlier models (like o1), the new GPT-5.2 series (Dec 2025) has mastered this approach. Both standard and Pro models "think" before answering, with GPT-5.2 Pro capable of sustained reasoning for deep research and complex coding.
