OpenAI has begun rolling out an enhanced memory feature for free ChatGPT users, allowing the AI to reference past conversations for more relevant responses. The update, confirmed in an OpenAI support document, started phasing in on June 3, 2025, for logged-in free users.
Previously a feature primarily available to paid subscribers, this upgrade enables ChatGPT to save conversational context for a longer duration. This means if a user provides a specific instruction or preference, ChatGPT is more likely to remember and apply it in subsequent interactions. OpenAI stated that in addition to previously saved memories, ChatGPT will now leverage recent conversations to provide answers that are more tailored and relevant to the user.
However, while an improvement for free users, this version of the memory feature has limitations. Free accounts receive a lighter version, designed for short-term continuity across conversations. In contrast, paid subscribers (ChatGPT Plus at $20/month and ChatGPT Pro at $200/month) have access to a more powerful memory function that can reference much older messages.
Users who prefer not to have ChatGPT retain information from their past conversations have options. The memory feature, labeled as “Reference chat history,” can be toggled off within the ChatGPT Settings. Additionally, users can manually remove specific stored memories they deem unnecessary or sensitive. For conversations that should leave no trace, ChatGPT offers a “Temporary Chat” feature, which operates similarly to incognito mode in web browsers.
