About ChatGPT
ChatGPT is OpenAI's conversational AI assistant, launched in 2022 and now one of the most widely used AI products in the world. It handles open-ended conversation, writing, coding, research, and data analysis, and as of mid-2026 runs on the GPT-5.6 model family, which OpenAI splits into three tiers: Sol for the most demanding reasoning and coding tasks, Terra for balanced everyday use, and Luna for faster, lower-cost work. OpenAI reports the newer models hallucinate far less than earlier GPT-4o-era versions and lead independent coding benchmarks such as SWE-bench Verified. The product is available on the web, as native apps for iOS, Android, Windows, and macOS, and through OpenAI's developer API, which lets other companies build ChatGPT's underlying models into their own products. OpenAI has also launched an AI-powered browser, ChatGPT Atlas, currently available on macOS with Windows, iOS, and Android versions planned. Free, Plus, Pro, Business, and Enterprise plans offer different usage limits and model access. ChatGPT's broad usage and general-purpose design come with a tradeoff: it is not tailored to any one company's data or workflow the way narrower, purpose-built assistants are, so answers about a specific business still typically require custom prompting or connected data sources.

How It Works
- 1ChatGPT is fine-tuned from large language models (LLMs) such as GPT-3.5 and GPT-4o.
- 2It is optimized for dialogue using Reinforcement Learning with Human Feedback (RLHF), where human demonstrations and preference comparisons guide the model toward desired behavior.
- 3The model generates conversational responses based on the input it receives from users.
- 4For voice interactions, it uses a pipeline of three separate models: one for transcribing audio to text, an LLM (GPT-3.5 or GPT-4o) for processing text and generating responses, and another for converting text back to audio.
How to Use ChatGPT
