Dreaming: ChatGPT launches stronger memory system to better remember user preferences

Dreaming： ChatGPT 推出更强的记忆系统，更好记住用户偏好

ChatGPT launched Dreaming, a memory system for remembering user preferences and keeping context relevant across conversations; the post does not disclose rollout scope, default settings, or retention period.

Why it matters: OpenAI product update with clear HKR-H/K/R: a named ChatGPT memory system, cross-chat preference retention, and privacy resonance. Missing rollout, default setting, and retention details keep it below 85.
