comemo 1.2.0

Python SDK for CoMemo

CoMemo SDK

Python SDK for CoMemo — a multi-module hybrid memory system powered by Pinecone and Neo4j.

Installation

pip install comemo

Quick Start

Each client requires your own infrastructure credentials. All operations use your own Pinecone index, Neo4j database, and LLM API key.

from comemo import MemoryClient

client = MemoryClient(
    llm_api_key="sk-your-openai-key",
    model="gpt-4o-mini",
    pinecone_api_key="pc-...",
    pinecone_index="my-memory-index",
    neo4j_uri="neo4j+s://xxx.databases.neo4j.io",
    neo4j_username="neo4j",
    neo4j_password="...",
)

Core Memory

# Add a memory
result = client.add_memory("john", "chat_01", "I work at Google as a software engineer")
print(result.status)     # "success"
print(result.action)     # "NEW"
print(result.memory_id)  # "mem_abc123"

# Delete all user memories
client.delete_user_memories("john")

# Delete session memories
client.delete_session_memories("john", "chat_01")

# Delete a single memory
client.delete_memory("mem_abc123")

Retrieval

# Simple retrieve
result = client.retrieve("john", "chat_01", "Where does John work?", top_k=5)
for m in result.memories:
    print(f"{m.fact} (score: {m.score:.2f})")

# Advanced retrieve with full scoring breakdown
result = client.retrieve_advanced(
    user_id="john",
    session_id="chat_01",
    query="career and hobbies",
    top_k=10,
    expand_context=True,
    expand_graph=True,
    min_score=0.3,
    reinforce=True,
)
for m in result.memories:
    print(f"{m.fact} | semantic={m.semantic_similarity:.2f} graph={m.graph_relevance:.2f}")

# List memories across all sessions
result = client.list_memories("john", query="work", top_k=10)

# Retrieve with LLM summary
summary = client.retrieve_summary("john", "chat_01", "Tell me about John's career")
print(summary.summary)

Maintenance

# Run maintenance tasks (decay, forgetting, summarization)
result = client.run_maintenance("john")

# Selective tasks
result = client.run_maintenance(
    "john",
    tasks={"decay": True, "forgetting": True, "summarization": False},
)

# Dry run
result = client.run_maintenance("john", dry_run=True)

System

health = client.health()
print(health.status)        # "healthy"
print(health.version)       # "6.0.0"
print(health.architecture)  # "Multi-Module Hybrid Memory (Multi-Tenant)"

Context Manager

with MemoryClient(
    llm_api_key="sk-...",
    pinecone_api_key="pc-...",
    pinecone_index="my-index",
    neo4j_uri="bolt://localhost:7687",
    neo4j_username="neo4j",
    neo4j_password="...",
) as client:
    client.add_memory("john", "chat_01", "My favorite color is blue")

Error Handling

from comemo import MemoryClient, ValidationError, NotFoundError

try:
    client.retrieve("john", "chat_01", "")
except ValidationError as e:
    print(f"Bad request: {e.message}")
except NotFoundError as e:
    print(f"Not found: {e.message}")
