Comparing Memory Systems for LLM Agents: Vector, Graph, and Event Logs

On November 10, 2025, an article titled 'Comparing Memory Systems for LLM Agents: Vector, Graph, and Event Logs' was published on MarkTechPost, addressing a critical aspect of multi-agent systems: memory design. The piece emphasizes that reliable systems largely depend on how memory is structured, retrieved, and managed, particularly in scenarios where memory may be inaccurate or absent. It presents a comparison of six distinct memory system patterns utilized in LLM agents, underscoring the necessity for explicit mechanisms to facilitate agent collaboration and tool interaction. This exploration is timely, as the field of AI continues to evolve, necessitating robust frameworks for memory management to enhance the functionality and reliability of multi-agent systems.
