Core Features of Mem0

Multi-Level Memory

Mem0 supports multiple levels of memory, including user memory for individual preferences, session memory for ongoing interactions, and AI agent memory for operational context.

memory.add("User prefers dark mode.", user_id="user123")
session_info = memory.search("preferences", user_id="user123")
print(session_info)

Adaptive Personalization

Mem0 dynamically learns from interactions to provide tailored experiences. It ensures that user inputs influence responses and recommendations effectively.

def adapt_response(user_input, user_id):
    memory.add(user_input, user_id=user_id)
    return f"Updated preferences for user {user_id}."

adapt_response("Prefers email over chat.", "user123")

Hybrid Database Approach

Mem0 integrates a vector database for embeddings, a key-value database for structured data, and a graph database for relationships.

memory.add("John is Sarah's manager.", user_id="user123", metadata={"type": "relationship"})
graph_query = memory.search("manager", user_id="user123", context_type="graph")
print(graph_query)

Dynamic Context Management

Mem0 evaluates memories based on relevance, importance, and recency, dynamically adjusting the context for efficiency.

def prioritize_memories(memories):
    scored = [{"memory": mem, "score": mem['relevance'] * 0.6 + mem['recency'] * 0.4} for mem in memories]
    return sorted(scored, key=lambda x: x["score"], reverse=True)

Developer-Friendly API

Mem0’s API simplifies the integration of memory management into AI workflows.

from mem0 import Memory

memory = Memory()
memory.add("User prefers vegan meals.", user_id="user456")
results = memory.search("vegan meals", user_id="user456")
print(results)

How Mem0 Works: The Hybrid Database Approach

Mem0’s architecture integrates multiple database types to optimize memory storage and retrieval.

Adding Memories

memory.add("Alice likes jazz music.", user_id="user789", metadata={"genre": "jazz"})

Retrieving Memories

memories = memory.search("favorite genre", user_id="user789")
print(memories)

Dynamic Scoring

scored_memories = prioritize_memories(memories)
print(scored_memories)

---

Advanced Components

Graph Memory

Mem0 uses Neo4j to model and retrieve complex relationships.

memory.configure_graph({"provider": "neo4j", "host": "localhost", "port": 7687})
memory.add("Alice is Bob's colleague.", user_id="user123", context_type="graph")
relationships = memory.search("colleague", user_id="user123", context_type="graph")
print(relationships)

Vector Databases

Mem0 enables semantic search through embeddings.

memory.configure_vector({"provider": "chroma"})
memory.add("Artificial Intelligence trends in 2023.", user_id="user999", context_type="vector")
semantic_search = memory.search("AI trends", user_id="user999", context_type="vector")
print(semantic_search)

Custom Prompts

Define custom prompts for better control over memory extraction.

custom_prompt = """
Extract details about:
- User preferences
- Task priorities
- Feedback
"""
memory.configure_prompt(custom_prompt)
