ChatGPT's official iOS app has received a major update (version 1.2024.150), bringing a revolutionary feature that allows users to continue their conversation with ChatGPT while using other apps. This update undoubtedly provides iPhone users with a powerful interactive experience comparable to the desktop version. It is worth noting that this new multitasking feature of ChatGPT is not enabled by default. Users need to manually enable it to enjoy the convenience of cross-app conversations. Here are the detailed steps to enable it: First, users need to update the ChatGPT app to the latest version to ensure they have access to the newest features and optimizations. Then, in the app interface, click on the username at the bottom of the sidebar to enter the app settings page. In the settings page, users need to scroll down to the "Background Conversations" option and enable it. Once these steps are completed, users can enjoy the convenience brought by this new feature. After enabling the background conversations feature, users can easily initiate voice conversations with ChatGPT. Even when leaving the ChatGPT app and switching to other apps, users can continue their voice communication with ChatGPT. This implementation greatly expands the application scenarios of ChatGPT, allowing users to enjoy the convenience of intelligent conversations in more situations. However, the actual performance of this new feature still needs to be further experienced by users. It is currently unclear how much impact this background running feature will have on device performance or battery life. Nevertheless, judging from the functionality itself, its power is beyond doubt and undoubtedly reduces the limitations of the ChatGPT app, providing users with a more convenient and intelligent interactive experience. It is worth noting that this upgrade may herald the arrival of GPT-4o Voice. GPT-4o Voice is a new voice recognition system that OpenAI is about to launch, expected to debut in OpenAI's spring update. Unlike existing voice recognition systems, GPT-4o Voice will achieve direct speech-to-speech conversion without the need to first convert text to speech and then convert speech back to text, thereby providing users with a more natural and fluent interactive experience. These series of innovative initiatives by OpenAI undoubtedly promote the development of artificial intelligence technology in the field of conversational systems. In the future, we have reason to expect OpenAI to continue launching more excellent products and services, bringing more convenience and enjoyment to human life.
