We’re thrilled to announce cross-thread memory support in LangGraph, available for both Python and JavaScript. This new feature lets your agents store and recall information between conversation threads for smarter, more adaptive interactions.

Key Benefits of Cross-Thread Memory:

• Persistent Memory: Store and recall information across different conversation sessions.

• Flexible Namespacing: Organize memories using custom namespaces for different users, organizations, or contexts.

• JSON Document Storage: Save memories as JSON documents, making it easy to manipulate and retrieve data.

• Content-Based Search: Easily filter and search memories across namespaces based on content.

Why Cross-Thread Memory?

Most AI agents today lose context between conversations, severely limiting their potential. LangGraph now changes this by providing a simple, reliable, persistent memory layer that works across threads, allowing your agents to learn from user feedback, retain preferences, and continuously improve.
