  ChatGPT is a conversational chatbot and artificial intelligence assistant based on large language models. It can write and debug computer programs; compose music, teleplays, fairy tales, and student essays; answer test questions (sometimes, depending on the test, at a level above the average human test-taker); generate business ideas; write poetry and song lyrics; translate and summarize text; simulate a Linux system; simulate entire chat rooms; or play games like tic-tac-toe.
  
  OpenAI added features to ChatGPT on many occasions after its initial release.
  
  Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. The user's inputs to these conversations are referred to as prompts. They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations. ChatGPT can also decide for itself to remember details. Users can also choose to disable the memory feature. To prevent offensive outputs from being presented to and produced by ChatGPT, queries are filtered through the OpenAI "Moderation endpoint" API (a separate GPT-based AI).
  
  In March 2023, OpenAI added support for plugins for ChatGPT. This includes both plugins made by OpenAI, such as web browsing and code interpretation, and external plugins from developers such as Expedia, OpenTable, Zapier, Shopify, Slack, and Wolfram.
  
  In October 2024, the ChatGPT Search feature was introduced, which allows ChatGPT to search the web (either on demand or based on the nature of the questions asked) for more accurate and up-to-date responses. This feature, originally available to paying users only, was made available to all logged-in users in December 2024, and finally to all users in February 2025.
  
  In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free.
