OpenAI has launched an improved memory feature for ChatGPT. CEO Sam Altman announced the upgrade, which allows the AI to better recall previous conversations and user information. The feature is rolling out to Pro users first, with Plus subscribers gaining access soon. OpenAI views this as a significant step towards more personalized AI systems. Users can opt out or use temporary conversations if desired. The upgrade aims to make ChatGPT more useful by building a comprehensive understanding of each user over time.
