OpenAI has announced significant updates to its ChatGPT product, including a new feature called 'Canvas' that enhances collaborative writing and coding capabilities. This feature allows users to brainstorm, write, and code alongside ChatGPT, providing in-line feedback and a more interactive experience. Additionally, as part of a partnership with Apple, ChatGPT will now be integrated with Siri on iOS 18.2, enabling users to access ChatGPT's functionalities through voice commands. This integration aims to improve user queries across text, voice, or video formats. The updates were highlighted during OpenAI's '12 Days of Ship-mas' event, which showcases new features and partnerships. The Canvas feature is now available to all users via the web app, making it a powerful tool for programming and creative tasks.
