How to free up memory storage on ChatGPT

• ChatGPT’s memory stores information you’ve chosen to share across sessions. If you see the “memory full” message, you’ve reached the storage limit. You can free up space by deleting individual memories or clearing all memory from the “Manage memories” setting.

If you’ve seen the “memory full” message on ChatGPT, it means the AI has reached its storage limit for personalization data. This feature stores details you’ve chosen to share, such as your name, writing style, and goals, so the chatbot can tailor responses. Clearing old or unneeded memories lets you store new preferences and keeps ChatGPT personalized to you, and in this guide, I’ll explain how to complete this task.

How ChatGPT memory works

When using ChatGPT, OpenAI stores only the information you explicitly choose to share or confirm when prompted. This “memory” is different from chat history, it persists across sessions and is used for personalization.

OpenAI hasn’t disclosed the exact storage size, but it’s finite. Free users have less capacity than paid subscribers. When you see “memory full,” you’ll need to delete old entries or clear all memory before storing new ones, just as your Windows 11 computer can run out of storage space when storing too many files.

How to fix the ‘memory full’ message on ChatGPT

To delete memories stored on ChatGPT, follow these steps:

1. Open your ChatGPT account.

2. Click on your profile and select the Settings option.

   

3. Click on Data controls.

4. Click the “Personalization” option.

5. Click the Manage button for the “Manage memories” setting.

   

6. (Option 1) Click the Delete (trashcan) button for each memory you want to erase.

   

7. (Option 2) Click the Delete all button to clear and reset the ChatGPT memory.

8. Click the Close button.

Once you complete the steps, the chatbot will have more space to store more memories.

Alongside the ability to manage the storage, you can also change other settings to improve your experience and privacy. For example, you can prevent OpenAI from using the data for AI training purposes, and you can manage and delete shared links to prevent your chats from ending up in search engines or in the wrong hands.
