GPT-4o Memory Now On By Default for All Plus Users
OpenAI enabled persistent memory by default for all ChatGPT Plus and Pro users. The model automatically saves facts, preferences, and context from conversations and references them in future sessions.
ChatGPT now behaves like a persistent assistant that remembers your stack, goals, and preferences across sessions without any prompt engineering.
No action needed — memory is automatic. View and edit stored memories in Settings → Personalization → Manage Memory.
The shift to default-on memory changes ChatGPT from a stateless tool to a persistent collaborator. Power users can seed it with context about their projects, coding preferences, and communication style once and benefit across every future session. Memory can be fully disabled or selectively edited from settings.
