Installation Steps

# Clone the repository
git clone https://github.com/infiniflow/ragflow.git
cd ragflow

# Start with Docker Compose
docker compose up -d

# Access the web interface
# Navigate to http://localhost
# Default credentials: admin@infiniflow.com / infiniflow

Environment Configuration

Create a .env file for production deployment:

# Database Configuration
MYSQL_PASSWORD=your_secure_password
MYSQL_HOST=mysql
MYSQL_PORT=3306

# Vector Database
ES_PASSWORD=your_es_password
ES_HOST=elasticsearch
ES_PORT=9200

🔧 Advanced Configuration

LLM Integration

RAGFlow supports multiple LLM providers. Configure your preferred model:

# Example: OpenAI Configuration
from ragflow import RAGFlow

# Initialize RAGFlow client
ragflow = RAGFlow(api_key="your_api_key", base_url="http://localhost")

# Configure LLM
llm_config = {
    "model_name": "gpt-4",
    "api_key": "your_openai_key",
    "temperature": 0.1,
    "max_tokens": 2048
}

# Set up the model
ragflow.set_llm(llm_config)

Document Processing Pipeline

RAGFlow's document processing is highly configurable:

# Create a knowledge base
kb = ragflow.create_dataset(name="Enterprise_Docs")

# Configure parsing strategy
parse_config = {
    "chunk_method": "intelligent",
    "chunk_size": 1024,
    "overlap": 128,
    "parse_method": "auto",  # or "mineru", "docling"
    "ocr_enabled": True
}

# Upload and process documents
documents = [
    "/path/to/document1.pdf",
    "/path/to/document2.docx",
    "/path/to/document3.txt"
]

for doc_path in documents:
    kb.upload_file(
        file_path=doc_path,
        parse_config=parse_config
    )

🤖 Building Agentic Workflows

RAGFlow's agent capabilities enable sophisticated AI workflows:

Creating a Research Agent

# Define agent configuration
agent_config = {
    "name": "Research_Assistant",
    "description": "AI agent for document research and analysis",
    "llm": "gpt-4",
    "prompt_template": """
    You are a research assistant. Analyze the provided documents and:
    1. Extract key insights
    2. Identify patterns and trends
    3. Provide actionable recommendations
    
    Context: {context}
    Question: {question}
    """,
    "tools": ["document_search", "web_search", "calculator"]
}

# Create the agent
agent = ragflow.create_agent(agent_config)

# Configure memory for conversation history
agent.enable_memory(
    memory_type="conversation",
    max_tokens=4096
)

Multi-Agent Orchestration

# Create a multi-agent workflow
workflow = ragflow.create_workflow("Document_Analysis_Pipeline")

# Add agents to workflow
research_agent = workflow.add_agent("researcher", agent_config)
analysis_agent = workflow.add_agent("analyzer", analysis_config)
summary_agent = workflow.add_agent("summarizer", summary_config)

# Define workflow steps
workflow.add_step(
    name="research",
    agent=research_agent,
    input_from="user"
)

workflow.add_step(
    name="analyze",
    agent=analysis_agent,
    input_from="research"
)

workflow.add_step(
    name="summarize",
    agent=summary_agent,
    input_from="analyze"
)

# Execute workflow
result = workflow.run(
    input_data="Analyze the quarterly financial reports"
)
