ChatGPT release notes: Project-only memory (via) The feature I've most wanted from ChatGPT's memory feature (the newer version of memory that automatically includes relevant details from summarized prior conversations) just landed:
With project-only memory enabled, ChatGPT can use other conversations in that project for additional context, and won’t use your saved memories from outside the project to shape responses. Additionally, it won’t carry anything from the project into future chats outside of the project.
This looks like exactly what I described back in May:
I need control over what older conversations are being considered, on as fine-grained a level as possible without it being frustrating to use.
What I want is memory within projects. [...]
I would love the option to turn on memory from previous chats in a way that’s scoped to those projects.
Note that it's not yet available in the official chathpt mobile apps, but should be coming "soon":
This feature will initially only be available on the ChatGPT website and Windows app. Support for mobile (iOS and Android) and macOS app will follow in the coming weeks.
