SKU: langmem
LangMem is a software development kit (SDK) designed to enhance AI agents by integrating long-term memory capabilities. It allows agents to extract important information from interactions, optimize behavior through prompt refinement, and maintain knowledge over time. Compatible with various storage systems and natively integrating with LangGraph's storage layer, LangMem enables continuous improvement, personalized responses, and consistent behavior across sessions.

Developers aiming to create AI agents with adaptive learning and long-term memory.
Enhancing conversational AI systems to remember user preferences and past interactions.
Implementing personalized AI assistants capable of continuous improvement.
Building AI agents that maintain consistent behavior across multiple sessions.
LangMem demonstrates substantial autonomy through its self-improvement capabilities and memory management, but retains human oversight constraints. The system autonomously optimizes prompts (source ), consolidates memories through background processes (source ), and enables multi-agent learning (source ). However, autonomy is bounded by predefined tool configurations (source ), storage implementations requiring developer input (source ), and the need for initial human feedback to start optimization loops (source ). The framework allows code execution (source ) but limits environment access through its store implementations, placing it in the upper-middle autonomy tier compared to frameworks like AutoGen (source ).
