OpenAI has announced that the legacy ChatGPT Classic app will officially be discontinued on January 30, 2027, with users able to migrate their entire chat history to the new ChatGPT app to access the latest features. OpenAI had previously launched a new ChatGPT desktop app that integrates multiple features and renamed the original standard app ChatGPT Classic. The new version initially drew controversy for replacing the native macOS app with the Electron framework and for its cluttered interface design. OpenAI has since gradually refined and optimized the new interface, while ChatGPT Classic has largely stopped receiving updates. As new models become increasingly tightly integrated with app-exclusive features, Classic's reliability has continued to decline. OpenAI is now preparing to test a unified interface that combines Chat and Work features, initially opening it to a small group of users so they can access both conversational features and Work's advanced capabilities within the same interface. The company had previously said it planned to fold Work features into the regular ChatGPT experience.
