OpenAI plans to launch a new feature called 'Project Sunshine' to make ChatGPT more personalized. The upgrade includes more coherent conversations, continually improving learning capabilities, and custom memory functions. In 2024, an upgrade to the GPT Store is planned, adding search functionality and showcasing the best custom GPT applications. The temporary chat function will provide information that is only used within the current chat window, facilitating shared accounts for multiple teams. ChatGPT will have enhanced memory capabilities, allowing users to personalize through settings.
