ChatGPT Plugins

Our custom GPTs are becoming ChatGPT plugins: the same tools, rebuilt so diagrams, slides, sheet music and charts appear right in the chat.

Why the change? OpenAI is retiring custom GPTs on December 11, 2026 and replacing them with plugins. Until then every classic GPT below keeps working. When a plugin goes live you can add it from the ChatGPT Plugins directory, then start a chat with @ and its name.
