Starting today forChatGPT Plus,Pro, andBusinessusers, long pastes are handled differently in ChatGPT.If you pastemore than 5k charactersinto the composer, ChatGPT will automatically convert the content into anattachmentinstead of inserting it directly into the text field. This keeps the composer cleaner and helps prevent large pastes from consuming your entire context window.You can still move the content back into the message at any time by clicking onShow in text fieldto convert the attachment back to a direct paste.

March 25, 2026 — Google Drive app unification

Google’s file connectors in ChatGPT are now unified under Google Drive, providing a single app experience for interacting with your Google Docs, Sheets and Slides on Google Drive.If you’re a new user, you can connect to the Google Drive app in ChatGPT to use Google Drive, Docs, Sheets, and Slides actions, removing the need to install and authenticate separate Google file apps. If you’ve already connected to the separate apps in the past, they will continue to work as normal.
