ChatGPT

ChatGPT is the AI product built by OpenAI that became the fastest-adopted consumer technology product in history when it launched in November 2022, reaching 100 million users in two months. It is built on the GPT family of large language models and operates as a conversational interface — users ask questions and receive synthesized, paragraph-form answers rather than a list of links.

For communications professionals, ChatGPT is now one of the most important surfaces where brands, executives, and institutions are either found or missed. When a buyer researches a product category, a journalist researches a company, or a board researches a CEO before a governance decision, ChatGPT is frequently the first stop — before Google, before LinkedIn, before any direct source. The answer ChatGPT returns shapes the perception that follows.

ChatGPT does not retrieve answers in real time from the open web on standard queries. It synthesizes from its training data — a snapshot of the internet and published content at a specific point in time — plus live web browsing on queries that trigger search. The practical implication: brands need an editorial record that was in the training data and continues to be indexed, cited, and updated so that new training cycles incorporate current and accurate information.

ChatGPT's commercial products include the free consumer tier, ChatGPT Plus (GPT-4o, $20/month), ChatGPT Team, ChatGPT Enterprise (used by over 80% of Fortune 500 companies), and ChatGPT Edu. In October 2025, OpenAI launched ChatGPT Instant Checkout — a commerce surface enabling direct product purchases inside the chat interface, with Walmart as a launch partner.

Competing directly with ChatGPT: Claude (Anthropic), Gemini (Google), Perplexity, Grok (xAI), and Meta AI. ChatGPT remains the market leader by user volume and brand recognition. When people say "I asked AI," they are statistically most likely to mean ChatGPT.
