According to Sam Altman on Twitter, ChatGPT has updated its personalization page by consolidating personality configuration, custom instructions, and memory features into a single, streamlined interface. This change, rolling out over the next few days, is designed to improve usability and user experience for both individual and business users. The unified interface allows for more efficient workflow customization and deeper personalization, which creates new opportunities for enterprises to tailor AI interactions to their specific operational needs. This update also reflects a broader trend towards user-centric design in AI platforms, increasing adoption potential in enterprise and customer service environments (Source: Sam Altman, Twitter, Sep 16, 2025).
