OpenAI is expanding ChatGPT’s memory capabilities, allowing it to remember previous conversations—even ones you didn’t explicitly ask it to save. CEO Sam Altman announced on X that ChatGPT can now “reference all your past conversations,” calling the upgrade a step toward creating AI that better understands users over time.
This enhancement builds on ChatGPT’s existing “Memory” feature, introduced last year, which could store limited data like prompts and user preferences. With the new long-term memory update, ChatGPT can now retain information in two key ways: through “saved memories” users choose to keep, and “reference chat history,” which allows the AI to learn from past interactions to improve future responses.
The update is currently rolling out to ChatGPT Pro users (the $200/month tier), with availability for $20/month Plus users expected soon. OpenAI also plans to offer the feature to Team, Enterprise, and Education users in the coming weeks. However, it will not be available in the EU, UK, Switzerland, Norway, Iceland, or Liechtenstein—regions with stricter AI regulations that OpenAI has previously criticized.
Importantly, memory remains optional. Users can disable it through ChatGPT’s personalization settings or use the temporary chat feature, which prevents memory from being used or updated. The new memory functionality mirrors a similar upgrade from Google’s Gemini AI in February, designed to offer more personalized, context-aware responses based on prior interactions.
