OpenAI 重構 ChatGPT 記憶：引入「夢境」機制，讓 AI 真正記住你

openai deployed a revamped memory architecture for chatgpt dubbed 'dreaming', moving away from static, manually saved lists to a background process that synthesizes memories across chat history. the new system optimizes for freshness, correctness, and scalability, addressing the limitations of the previous saved memories feature which often became stale or incorrect over time. users can review and edit a memory summary, giving them control over the context the model carries forward. available initially to plus and pro users, this update is critical for openai's goal of building agents that retain context over years rather than just weeks.
