OpenAI has launched a significantly improved memory system for ChatGPT called "dreaming" that addresses staleness, correctness, and scalability challenges. This evolution from the 2024 "saved memories" feature represents the company's most capable memory system yet, automatically curating user context in the background. The update allows ChatGPT to maintain fresher, more relevant context across conversations without requiring explicit memory triggers.

The new dreaming-based system demonstrates measurable improvements in three key areas: carrying forward context, following user preferences, and staying current over time. This memory system is available to ChatGPT Plus and Pro users in the US today, with plans to expand to Free users and additional countries. Compute requirements were reduced by approximately 5x, making the system practical for broader deployment.

Memory serves as critical infrastructure for ChatGPT's personalization capabilities, allowing the AI to learn user preferences and constraints across conversations. The dreaming technology represents a fundamental shift from reactive to proactive memory management, automatically updating memories as time passes instead of becoming stale. This update provides a shared memory foundation for all users while enhancing the AI's ability to maintain relevant context over extended interactions.
