About ChatGPT
ChatGPT is an AI assistant developed by OpenAI, an AI company based in San Francisco. It launched in November 2022 and quickly became one of the most widely used AI tools in the world. ChatGPT works through conversation, you type a question or request, and it responds in plain language.
What ChatGPT does
People use ChatGPT for a wide range of everyday tasks: writing emails, drafting reports, summarising documents, translating text, brainstorming ideas, explaining difficult topics, and writing or debugging code. It can also handle longer work like research, analysis, and structured planning.
ChatGPT supports most major languages, including Finnish, Swedish, Norwegian, and Danish, though responses tend to be most polished in English.
The models behind it
ChatGPT is powered by OpenAI’s GPT family of models. Different versions are available depending on the plan you use, ranging from faster, lighter models for quick tasks to more capable models built for complex reasoning, longer documents, and detailed analysis. OpenAI updates these models regularly.
How to use it
The easiest way to try ChatGPT is at chat.openai.com or through the official mobile app. There is a free tier with basic access, and paid plans (ChatGPT Plus, Team, and Enterprise) offer more usage, faster responses, and access to advanced features such as image generation, file uploads, voice mode, and custom GPTs.
Developers can also access the underlying models through the OpenAI API to build their own applications.
