This feature aims to enhance professional and enterprise use of ChatGPT by allowing users to set specific tasks and prompts in advance. The event included live demos showcasing how 'Projects' can be applied in various scenarios, including home maintenance tasks like tracking filter changes, and programming tasks where users can upload documents like PDFs, function specifications, and JSON templates to generate websites. The release has been described as one of the most exciting in the series, with commentators noting its potential impact on professional workflows. Examples of 'Projects' include organizing a Secret Santa, and using ChatGPT for tasks like uploading PDFs, function specs, and JSON templates to generate websites.
