​
Quick Start

1

Install Package

First, install the PraisonAI Agents package:
pip install "praisonaiagents[memory]" duckduckgo_search
duckduckgo_search is a tool that allows agents to search the web. It is required for the multiple agents example shown below.
2

Set API Key

Set your OpenAI API key as an environment variable in your terminal:
export OPENAI_API_KEY=your_api_key_here
3

Create a file

Create a new file app.py with the basic setup:
from praisonaiagents.agents.agents import Agent, Task, PraisonAIAgents

# Create blog writer agent
blog_agent = Agent(
    role="Blog Writer",
    goal="Write a blog post about AI",
    backstory="Expert at writing blog posts",
    llm="gpt-4o-mini"
)

# Create blog writing task
blog_task = Task(
    description="Write a blog post about AI trends",
    expected_output="Well-written blog post about AI trends",
    agent=blog_agent
)

# Create and start the agents with memory enabled
agents = PraisonAIAgents(
    agents=[blog_agent],
    tasks=[blog_task],
    memory=True
)   

# Start execution
result = agents.start()
print(result)

Start Agents

Type this in your terminal to run your agents:
python app.py
Requirements
  • Python 3.10 or higher

Understanding Memory

What is Agent Memory?

Memory in AI agents enables them to:
  • Maintain context across multiple tasks
  • Remember previous interactions and findings
  • Build upon past knowledge
  • Share information between agents
  • Create more coherent and contextual responses

​
Features

Context Retention

Maintain information across multiple interactions.

Information Sharing

Share knowledge between multiple agents.

Long-term Storage

Store and retrieve information over extended periods.

Memory Types

Support for different memory types (short-term, long-term).

​
Multi-Agent Memory

from praisonaiagents import Agent, Task, PraisonAIAgents
from praisonaiagents.tools import duckduckgo

# Create first agent for research
researcher = Agent(
    role="Research Analyst",
    goal="Research and analyze market trends",
    backstory="Expert in market research and data analysis",
    tools=[duckduckgo],
    verbose=True
)

# Create second agent for report writing
writer = Agent(
    role="Report Writer",
    goal="Create comprehensive market reports",
    backstory="Expert in technical writing and report creation",
    verbose=True
)

# Create research task
research_task = Task(
    description="Research current market trends",
    expected_output="Detailed market analysis",
    agent=researcher
)

# Create writing task
report_task = Task(
    description="Create a market report based on research",
    expected_output="Comprehensive market report",
    agent=writer
)

# Create and start the agents with memory
agents = PraisonAIAgents(
    agents=[researcher, writer],
    tasks=[research_task, report_task],
    memory=True,
    process="sequential"
)

# Start execution
result = agents.start()

​
Configuration Options

# Create an agent with memory configuration
agent = Agent(
    role="Research Analyst",
    goal="Research and retain information",
    backstory="Expert in research and analysis",
    tools=[duckduckgo],
    verbose=True,  # Enable detailed logging
    llm="gpt-4o"  # Language model to use
)

# Create agents with memory options
agents = PraisonAIAgents(
    agents=[agent],
    tasks=[task],
    memory=True,  # Enable memory
    memory_config={
        "provider": "rag",  # Use RAG for semantic search
        "use_embedding": True,  # Enable embeddings for better search
        "short_db": ".praison/short_term.db",  # Path for short-term memory
        "long_db": ".praison/long_term.db",    # Path for long-term memory
        "rag_db_path": ".praison/chroma_db"    # Path for vector database
    }
)

​
Troubleshooting

Memory Issues

If memory isn’t working as expected:
  • Check memory configuration
  • Enable verbose mode for debugging
  • Verify memory provider settings

Context Flow

If context isn’t being maintained:
  • Review task dependencies
  • Check memory configuration
  • Verify agent communication

​
Memory Configuration Options

The memory system in PraisonAI supports various configuration options to customize how agents store and retrieve information: 
memory_config = {
    # Memory Provider
    "provider": "rag",        # Options: "rag", "mem0", "none"
    "use_embedding": True,    # Enable semantic search with embeddings
    
    # Storage Paths
    "short_db": ".praison/short_term.db",  # Short-term memory SQLite DB
    "long_db": ".praison/long_term.db",    # Long-term memory SQLite DB
    "rag_db_path": ".praison/chroma_db",   # Vector database path
    
    # Memory Settings
    "ttl": 3600,             # Time to live for memory items (in seconds)
    
    # Optional Mem0 Config (if using mem0 provider)
    "config": {
        "api_key": "...",    # Mem0 API key
        "org_id": "...",     # Organization ID
        "project_id": "..."  # Project ID
    }
}

# Create agents with memory configuration
agents = PraisonAIAgents(
    agents=[agent],
    tasks=[task],
    memory=True,
    memory_config=memory_config
)

​
Memory Types

PraisonAI’s memory system includes several types of memory:

Short-term Memory

  • Temporary storage for current context
  • Automatically cleared between sessions
  • Fast access for immediate task context

Long-term Memory

  • Persistent storage for important information
  • Semantic search capabilities with RAG
  • Quality-based storage decisions

​
Memory Quality Control

PraisonAI includes built-in quality control for memory storage: 
# Example of storing with quality metrics
agents.memory.store_long_term(
    text="Important information to remember",
    metadata={
        "task_id": "task_123",
        "agent": "research_agent"
    },
    completeness=0.9,    # How complete is the information
    relevance=0.85,      # How relevant to the task
    clarity=0.95,        # How clear and well-structured
    accuracy=0.9,        # How accurate is the information
    weights={            # Custom weights for quality score
        "completeness": 0.3,
        "relevance": 0.3,
        "clarity": 0.2,
        "accuracy": 0.2
    }
)

# Search with quality filter
results = agents.memory.search_long_term(
    query="search query",
    min_quality=0.8,     # Only return high-quality matches
    limit=5              # Maximum number of results
)
