ChatGPT took the world by storm almost overnight, becoming one of the fastest-growing consumer products in history. Built by OpenAI, it can hold conversations, write stories, answer tricky questions, and switch between languages with ease.
Here are 10 fun, verified facts about ChatGPT that explain how it works and why it became such a phenomenon.
ChatGPT was released to the public on November 30, 2022, as a free research preview built on OpenAI's GPT-3.5 model.
It reached 1 million users within just 5 days of launch and an estimated 100 million monthly active users within about two months, making it one of the fastest-adopted consumer products ever.
"GPT" stands for Generative Pre-trained Transformer, describing how the model generates text using a transformer neural network pre-trained on huge amounts of text.
ChatGPT can understand and generate text in many languages, including English, Spanish, French, German, and Chinese, though it performs best in English since most of its training data is in that language.
The model writes in a conversational, human-like style by predicting the most likely next word based on patterns learned from massive volumes of text during training.
Modern versions of ChatGPT use a tokenizer with a vocabulary of roughly 100,000 tokens (word pieces), which it combines to represent virtually any word or phrase.
ChatGPT can write original stories, poems, and scripts, generating plots and characters based on a simple prompt.
It can break complex questions down into smaller steps and reason through them to produce a more complete answer.
Within a single conversation, ChatGPT keeps track of context, so it can refer back to earlier messages and follow up coherently.
ChatGPT itself does not learn or update in real time from your conversations; OpenAI periodically retrains and releases new versions of the underlying model instead.
Businesses use ChatGPT for a wide range of tasks, including drafting customer service replies, summarizing documents, writing code, and generating marketing copy.
ChatGPT is a product of OpenAI, an AI research company co-founded in 2015 that has stated a mission of ensuring artificial general intelligence benefits humanity.
Later versions of ChatGPT, including those built on GPT-4 and beyond, added the ability to understand images and generate more nuanced, longer-form responses.
