greeum 0.5.0

LLM-Independent Memory System with Multilingual Support

Greeum v0.5.0

An LLM-Independent Memory System with Multilingual Support

?뱦 Overview

Greeum (pronounced as "gree-um") is a universal memory module that can be attached to any LLM model, designed to:

• Track user's long-term utterances, goals, emotions, and intentions
• Recall memories relevant to the current context
• Process temporal reasoning in multiple languages
• Function as an "AI with memory"

The name "Greeum" is inspired by the Korean word "洹몃━?€" which evokes a sense of longing and remembrance - perfectly capturing the essence of a memory system.

?뵎 Key Features

• Long-Term Memory Blocks: Blockchain-like structure for immutable memory storage
• Short-Term Memory Management: TTL (Time-To-Live) structure for fluid temporary memories
• Semantic Association: Keyword/tag/vector-based memory recall system
• Waypoint Cache: Automatically retrieves memories related to the current context
• Prompt Composition: Automatic generation of LLM prompts that include relevant memories
• Temporal Reasoning: Advanced time expression recognition in multiple languages
• Multilingual Support: Automatic language detection and processing for Korean, English, and more
• Model Control Protocol: For MCP support, please check out GreeumMCP - a separate package that enables Greeum to connect with Cursor, Unity, Discord and other tools

?㎦ Usage

CLI Interface

# Add long-term memory
python cli/memory_cli.py add -c "I started a new project and it's really exciting"

# Search memories by keywords
python cli/memory_cli.py search -k "project,exciting"

# Search memories by time expression
python cli/memory_cli.py search-time -q "What did I do 3 days ago?" -l "auto"

# Add short-term memory
python cli/memory_cli.py stm "The weather is nice today"

# Retrieve short-term memories
python cli/memory_cli.py get-stm

# Generate a prompt
python cli/memory_cli.py prompt -i "How is the project going?"

REST API Server

# Run the API server
python api/memory_api.py

Web interface: http://localhost:5000

API Endpoints:

• GET /api/v1/health - Check status
• GET /api/v1/blocks - Retrieve block list
• POST /api/v1/blocks - Add a block
• GET /api/v1/search?keywords=keyword1,keyword2 - Search by keywords
• GET /api/v1/search/time?query=yesterday&language=en - Search by time expression
• GET, POST, DELETE /api/v1/stm - Manage short-term memory
• POST /api/v1/prompt - Generate prompts
• GET /api/v1/verify - Verify blockchain integrity

Python Library

from greeum import BlockManager, STMManager, CacheManager, PromptWrapper
from greeum.text_utils import process_user_input
from greeum.temporal_reasoner import TemporalReasoner

# Process user input
user_input = "I started a new project and it's really exciting"
processed = process_user_input(user_input)

# Store memory with block manager
block_manager = BlockManager()
block = block_manager.add_block(
    context=processed["context"],
    keywords=processed["keywords"],
    tags=processed["tags"],
    embedding=processed["embedding"],
    importance=processed["importance"]
)

# Time-based search (multilingual)
temporal_reasoner = TemporalReasoner(db_manager=block_manager, default_language="auto")
time_query = "What did I do 3 days ago?"
time_results = temporal_reasoner.search_by_time_reference(time_query)

# Generate prompt
cache_manager = CacheManager(block_manager=block_manager)
prompt_wrapper = PromptWrapper(cache_manager=cache_manager)

user_question = "How is the project going?"
prompt = prompt_wrapper.compose_prompt(user_question)

# Pass to LLM
# llm_response = call_your_llm(prompt)

Branch Management

• main: Stable release version branch
• dev: Core feature development branch (merged to main after testing)
• test-collect: Performance metrics and A/B test data collection branch

?뱤 Performance Tests

Greeum conducts performance tests in the following areas:

T-GEN-001: Response Specificity Improvement Rate

• Measures response quality improvement when using Greeum memory
• Confirmed 18.6% average quality improvement
• Increase of 4.2 specific information points per response

T-MEM-002: Memory Search Latency

• Measures speed improvement through waypoint cache
• Confirmed 5.04x average speed improvement
• Up to 8.67x speed improvement for 1,000+ memory blocks

T-API-001: API Call Efficiency

• Measures reduction in follow-up questions due to memory-based context
• Confirmed 78.2% reduction in need for follow-up questions
• Cost savings from reduced API calls

?뱤 Memory Block Structure

{
  "block_index": 143,
  "timestamp": "2025-05-08T01:02:33",
  "context": "I started a new project and it's really exciting",
  "keywords": ["project", "start", "exciting"],
  "tags": ["positive", "beginning", "motivated"],
  "embedding": [0.131, 0.847, ...],
  "importance": 0.91,
  "hash": "...",
  "prev_hash": "..."
}

?뵥 Supported Languages

Greeum supports time expression recognition in the following languages:

• ?눖?눟 Korean: Native support for Korean time expressions (?댁젣, 吏€?쒖＜, 3???? etc.)
• ?눣?눡 English: Full support for English time formats (yesterday, 3 days ago, etc.)
• ?뙋 Auto-detection: Automatically detects the language and processes accordingly

?뵇 Temporal Reasoning Examples

# Korean
result = evaluate_temporal_query("3???꾩뿉 萸??덉뼱?", language="ko")
# Returns: {detected: True, language: "ko", best_ref: {term: "3????}}

# English
result = evaluate_temporal_query("What did I do 3 days ago?", language="en")
# Returns: {detected: True, language: "en", best_ref: {term: "3 days ago"}}

# Auto-detection
result = evaluate_temporal_query("What happened yesterday?")
# Returns: {detected: True, language: "en", best_ref: {term: "yesterday"}}

?뵩 Project Extensions

• Enhanced Multilingual Support: Expanding to Japanese, Chinese, Spanish and more languages
• Embedding Improvements: Integration with real embedding models (e.g., sentence-transformers)
• Keyword Extraction Enhancement: Implementation of language-specific keyword extraction
• Cloud Integration: Addition of database backends (SQLite, MongoDB, etc.)
