OpenAI has significantly enhanced ChatGPT's memory and customization. Previously, a limited "Memory" feature required users to manually input information. Now, a new "reference chat history" option allows ChatGPT to access and utilize the entire conversation history to personalize responses, learning user preferences over time. This surpasses the old feature's limited fact retention, offering a more dynamic and context-aware interaction.
