Memo: Building Production-Ready AI Agents with Scalable Long-Term Memory
Large Language Models (LLMs) struggle with long-term conversational coherence due to fixed context windows. The Memo architecture introduces a scalable, memory-centric approach that dynamically extracts, consolidates, and retrieves salient information, enabling AI agents to maintain consistency over prolonged, multi-session dialogues.
Quantifiable Enterprise Impact
MemO's innovative memory architecture delivers significant improvements in AI agent performance and efficiency, critical for production-ready deployments.

Memo (Base Architecture)
Memo implements a novel paradigm that extracts, evaluates, and manages salient information from conversations through dedicated modules for memory extraction and updation. It uses a two-phase pipeline: extraction (processing new messages with conversation summary and recent history to extract salient memories) and update (evaluating candidate facts against existing memories using LLM-based tool calls for ADD, UPDATE, DELETE, NOOP operations to maintain consistency).
MemOᔢ (Graph-based Memory)
MemOᔢ extends the base Memo by incorporating graph-based memory representations. Memories are stored as directed labeled graphs with entities as nodes (e.g., ALICE, SAN_FRANCISCO) and relationships as edges (e.g., LIVES_IN). This structure allows for deeper understanding of connections between entities and supports advanced reasoning across interconnected facts, particularly for queries requiring complex relational paths.
Dataset
Evaluated on LOCOMO, a benchmark for long-term conversational memory with 10 extended conversations (avg. 600 dialogues, 26000 tokens) and 200 questions per conversation. Questions categorized into single-hop, multi-hop, temporal, and open-domain.
Evaluation Metrics
Assessed using LLM-as-a-Judge (J) for factual accuracy, relevance, completeness, and contextual appropriateness, overcoming limitations of lexical similarity metrics like F1 and BLEU-1. Deployment metrics tracked include Token Consumption and Latency (search and total).
Baselines
Compared against six categories: (i) established memory-augmented systems (LoCoMo, ReadAgent, MemoryBank, MemGPT, A-Mem), (ii) open-source memory solutions (LangMem), (iii) Retrieval-Augmented Generation (RAG) with varying chunk sizes/k-values, (iv) full-context processing, (v) OpenAI's proprietary memory, and (vi) dedicated memory management platforms (Zep).
Performance Summary
Memo and MemOᔢ consistently outperform existing memory systems across all question types in the LOCOMO benchmark. Memo achieves state-of-the-art in single-hop and multi-hop reasoning, while MemOᔢ unlocks significant gains in temporal and open-domain tasks, leveraging its structured graph representations. For example, Memo achieved a J-score of 67.13 for single-hop and 51.15 for multi-hop, significantly higher than most baselines. MemOᔢ achieved 58.13 for temporal and 75.71 for open-domain.
Latency & Efficiency
Memo achieves the lowest search latency (p50: 0.148s, p95: 0.200s) and total median latency (0.708s) among all methods, significantly outperforming full-context approaches (p95: 17.117s) with a 91% reduction. It also offers over 90% token cost savings. MemOᔢ introduces a moderate latency increase but still outperforms existing memory systems, demonstrating a practical balance between sophisticated reasoning and deployment constraints.

Reduction in P95 Latency vs. Full-Context
Memo significantly reduces computational overhead, making it ideal for real-time AI agent interactions without sacrificing response quality.

Real-World Impact: Personalized Recommendations
Imagine an AI assistant:
Without MemO: A user mentions being vegetarian and avoiding dairy. In a later session, the AI forgets and suggests 'Chicken Alfredo.' This breaks user trust and leads to inappropriate recommendations.
With MemO: The system dynamically extracts and stores the dietary preferences. In a subsequent session, it recalls this information and suggests a 'creamy cashew pasta sauce' – a contextually appropriate and helpful recommendation.
This simple example highlights MemO's ability to ensure consistent, personalized interactions by leveraging persistent, structured memory, fundamentally transforming AI agents from forgetful responders into reliable, long-term collaborators.
