Approaches for Managing Agent Memory

LangChain · Beginner ·📄 Research Papers Explained ·3mo ago
Humans refine their skills and learn preferences through experience. But many AI agents lack this capacity for continual learning. Here, we give an overview of memory in the DeepAgents CLI. Here, we talk about two methods for updating memory: "explicit" updating from user-provided instructions and "implicit" updating from reflection over past DeepAgent sessions. LangSmith fetch: https://github.com/langchain-ai/langsmith-fetch Claude Diary, an example reflection pattern: https://rlancemartin.github.io/2025/12/01/claude_diary/ Deepagents-CLI: https://github.com/langchain-ai/deepagents/tree/ma…
