rememhq 0.1.6

Reasoning memory layer for AI agents — Python SDK

remem Python SDK

The official Python SDK for remem — the reasoning memory layer for AI agents.

Remem provides a persistent, queryable memory system that uses LLM-powered reasoning for importance scoring, contradiction detection, knowledge graph construction, and session consolidation. This SDK offers a strongly-typed, fully asynchronous interface over the remem REST API using httpx and pydantic.

Key Features

• Fully Asynchronous: Built natively on asyncio and httpx.
• Type-Safe Models: Robust validation and autocompletion powered by Pydantic.
• LLM-Powered Reasoning: Effortlessly invoke semantic recall, importance scoring, and consolidation.
• Knowledge Graph: Native support for storing and querying relationship triples.

Installation

Install the package via pip or your preferred package manager (e.g., uv, poetry):

pip install rememhq

Quick Start

1. Start the remem API Server

Before using the SDK, start the rememhq-api server from the remem repository root:

cargo run -p rememhq-api -- --project default

By default, the server listens on http://localhost:7474.

2. Initialize the Client

import asyncio
from rememhq import Memory

async def main():
    # Initialize the memory client
    memory = Memory(
        base_url="http://localhost:7474",
        project="my-agent",
        reasoning_model="claude-sonnet-4-6"  # Configure the underlying reasoning engine
    )

    # Store a memory
    store_resp = await memory.store(
        content="The user prefers Python for ML tasks.",
        tags=["preferences", "ml"]
    )
    print(f"Stored memory ID: {store_resp.id}")

    # Recall memories using semantic reasoning
    results = await memory.recall(query="What language does the user prefer for machine learning?", limit=5)
    
    for result in results:
        print(f"Content: {result.content}")
        print(f"Reasoning trace: {result.reasoning}")

if __name__ == "__main__":
    asyncio.run(main())

Configuration Options

You can configure the SDK using constructor parameters or environment variables:

memory = Memory(
    base_url="http://localhost:7474",
    project="my-agent",
    reasoning_model="gpt-4o",
    timeout=30.0
)

Environment Variables:

• REMEM_API_URL — API server URL (default: http://localhost:7474)
• REMEM_PROJECT — Target project namespace (default: default)
• REMEM_REASONING_MODEL — Reasoning model (default: claude-sonnet-4-6)
• REMEM_TIMEOUT — Request timeout in seconds (default: 30)

API Reference

Memory Methods

• store(content: str, tags: list[str] = None, importance: float = None) -> StoreResponse: Store a new memory.
• recall(query: str, limit: int = 8) -> list[RecallResult]: Retrieve contextually relevant memories utilizing LLM evaluation.
• search(query: str, limit: int = 10) -> list[SearchResult]: Execute rapid full-text/vector search.
• update(memory_id: str, content: str) -> UpdateResponse: Modify existing memory content.
• forget(memory_id: str) -> ForgetResponse: Delete a specific memory item.
• consolidate(session_id: str) -> ConsolidateResponse: Transform short-term session logs into long-term durable facts.
