GPT-4o Persistent Memory Now On By Default for Plus & Pro
OpenAI flipped the switch on persistent memory for all Plus and Pro subscribers. ChatGPT now automatically stores facts, preferences, and context across all conversations without users needing to opt in or use custom instructions.
This fundamentally changes how power users interact with ChatGPT. No more re-explaining your stack, your preferences, or your projects every session. For indie hackers, this means ChatGPT can hold persistent context about your product, codebase preferences, and writing style.
Memory is automatic — just start working. Explicitly tell ChatGPT facts you want retained: 'remember that I always use TypeScript strict mode' or 'my main product is a B2B SaaS for HR teams'. Review and manage memories at Settings → Personalization → Memory.
GPT-4o memory goes on by default — your next ChatGPT session already knows who you are.
