Data to be translated: ChatGPT will undergo significant improvements in personalization as part of OpenAI's "Project Sunshine" upgrade. The enhancements include improved dialogue coherence, learning capabilities, and custom memory functions. The ephemeral chat feature will ensure that messages are only used within the current chat window and are not saved in the chat history. In 2024, OpenAI plans to roll out an upgrade to the GPT Store, adding search functionality and showcasing the most outstanding GPT custom applications. This upgrade to ChatGPT will make it smarter and more personalized, providing users with better assistant services.
