ChatGPT is a generative artificial intelligence chatbot designed to generate human-like text, speech, and images based on user prompts. Launched in November 2022 by OpenAI, it utilizes large language models (LLMs) and generative pre-trained transformers (GPTs), such as GPT-5, to perform a variety of tasks including writing, debugging code, composing music, answering questions, and simulating interactive environments. Sam Altman is the CEO of OpenAI.
Key features of ChatGPT include the ability to understand natural language, follow complex instructions, translate languages, analyze data, and generate images from text prompts. It can also remember user preferences over time to tailor responses based on previous interactions. In 2025, OpenAI added features to make ChatGPT more agentic, capable of autonomously performing longer tasks through web browser interactions. As of February 2026, ChatGPT is generally available, but some users have recently experienced increased errors and issues with loading conversations.
ChatGPT operates on a freemium model, offering a free version with limited access and several paid subscription plans. As of January 2026, available subscription tiers include ChatGPT Go at $8/month, Plus at $20/month, and Pro at $200/month. A Team plan is also available for $30 per user per month (or $25 per user per month if billed annually). An Enterprise plan with custom pricing is also available. Each tier offers varying levels of access to models like GPT-5, message limits, and additional features such as faster response times, image generation, and data analysis capabilities.
