Memory that stays more up to date

We’ve upgraded memory so ChatGPT can better keep your context up to date, helping responses stay more relevant. This makes memory more useful by reducing stale or contradictory saved memories and helps ChatGPT better understand your preferences, goals, and ongoing work. You can review the memories that ChatGPT may use to personalize responses through sources or in your memory summary.

Memories are now updated automatically, with ChatGPT keeping track of the details it determines are most important so it can continue building on the context you’ve already shared. If you prefer to revert to the legacy saved memories system, go to Settings > Memory > Saved memories.

This update is rolling out to Plus and Pro users in the US today. To access it on iOS or Android, update your ChatGPT app to the latest version. We’ll expand to Free and Go plans and additional countries over the next few weeks. Users will receive an in-product notice when the update becomes available to them. For Plus and Pro users, ChatGPT can also remember more useful context, with twice as much memory capacity.

Lockdown Mode is now available to all logged-in users

Lockdown Mode is now available to all logged-in users across account types and workspaces. It is an optional opt-in advanced security setting that limits access to the web and external services to help reduce the risk of data exfiltration from prompt injection attacks.

When Lockdown Mode is on, ChatGPT restricts network-enabled capabilities such as live web browsing, deep research, agent mode, file downloads, and some web-derived image support. Personal users can turn it on from Settings > Security. Workspace admins can configure access for members through workspace settings and role-based access controls.
