OpenAI has rolled out a significant upgrade to ChatGPT, enhancing its ability to find and remember details from past conversations. This improvement means that when 'reference chat history' is enabled, ChatGPT can more reliably recall specific information from previous interactions, leading to a more personalized and coherent user experience. Crucially, any past chat referenced by ChatGPT to answer a question will now appear as a source, allowing users to easily open and review the original context. This feature is currently available to ChatGPT Plus and Pro subscribers worldwide, making the AI chatbot a more effective and 'smarter' companion for its paid users. The update addresses a previous limitation where ChatGPT's recall could be spotty, particularly when users had numerous similar chat threads. OpenAI CEO Sam Altman highlighted this as a pivotal step towards AI systems that 'get to know you over your life, and become extremely useful and personalized.' While the core memory functionality that allows ChatGPT to learn user preferences was introduced earlier, this latest update specifically boosts its reliability in retrieving information from the entire chat history. Users retain full control over this feature, with options to manage memory settings or use 'Temporary Chat' for conversations they don't wish to be saved. The enhancement reflects ongoing efforts in the AI industry to create more intuitive and responsive conversational agents.
