ChatGPT
OpenAI's consumer-facing AI chatbot powered by GPT models. ChatGPT brought LLMs to the mainstream when it launched in November 2022, reaching 100 million users in two months.
Why It Matters
ChatGPT is the product that ignited the generative AI revolution. It proved that AI could be useful and accessible to everyday consumers, not just developers.
Example
A student using ChatGPT to understand a complex physics concept, a marketer drafting email copy, and a developer debugging code — all through natural conversation.
Think of it like...
Like the iPhone moment for AI — the technology existed before, but ChatGPT was the product that made it accessible to everyone.

GPT
Generative Pre-trained Transformer — a family of large language models developed by OpenAI. GPT models are trained to predict the next token in a sequence and can generate coherent, contextually relevant text across many tasks.
OpenAI
The AI research company that created GPT, ChatGPT, DALL-E, and Whisper. Originally founded as a nonprofit in 2015, OpenAI became the most prominent AI company after launching ChatGPT.
Large Language Model
A type of AI model trained on massive amounts of text data that can understand and generate human-like text. LLMs use transformer architecture and typically have billions of parameters, enabling them to perform a wide range of language tasks.
Conversational AI
AI technology that enables natural, multi-turn conversations between humans and machines. It combines NLU, dialog management, and NLG to maintain coherent, contextual interactions.
Generative AI
AI systems that can create new content — text, images, music, code, video — rather than just analyzing or classifying existing data. These models learn patterns from training data and generate novel outputs that resemble the original data.
