ChatGPT
ChatGPT is OpenAI's chat assistant, running on the GPT family of models — the best known and most used AI tool in the world.

Simply put#
ChatGPT is not a model but an interface in front of one. A GPT language model does the work; ChatGPT adds conversation, memory, file analysis, images and tools.
Example#
The same model is reachable through the API, without the chat interface — that is how developers build their own applications on it.
Why it matters to you#
The free tier uses conversations for training by default; paid and business accounts usually do not. If you paste work information in, that difference matters.
