OpenAI's AI assistant, with custom GPTs, deep research and image generation. Developers use the same models through the OpenAI API.
ChatGPT is OpenAI's AI assistant. You type or talk to it to write, research, read photos and documents, and make images. You can save instructions as a custom GPT for a job you repeat, and developers can use the same models in their own tools.
Used in the entries here for recipe ideas, shopping lists read from photos of inventory sheets, staff questions answered from a wiki, office paperwork and quick custom apps. Several builders call OpenAI's models from automation tools like n8n and Make.
