✨ Key Features

🌐 Supported Providers

PraisonAI supports 100+ LLM providers through seamless integration:

📘 Using Python Code

1. Single Agent

Create app.py file and add the code below:

from praisonaiagents import Agent
agent = Agent(instructions="Your are a helpful AI assistant")
agent.start("Write a movie script about a robot in Mars")

Run:

python app.py

2. Multi Agents

Create app.py file and add the code below:

from praisonaiagents import Agent, Agents

research_agent = Agent(instructions="Research about AI")
summarise_agent = Agent(instructions="Summarise research agent's findings")
agents = Agents(agents=[research_agent, summarise_agent])
agents.start()

Run:

python app.py

3. Agent with Planning Mode

Enable planning for any agent - the agent creates a plan, then executes step by step:

from praisonaiagents import Agent

def search_web(query: str) -> str:
    return f"Search results for: {query}"

agent = Agent(
    name="AI Assistant",
    instructions="Research and write about topics",
    planning=True,              # Enable planning mode
    planning_tools=[search_web], # Tools for planning research
    planning_reasoning=True      # Chain-of-thought reasoning
)

result = agent.start("Research AI trends in 2025 and write a summary")

What happens:

1. 📋 Agent creates a multi-step plan
2. 🚀 Executes each step sequentially
3. 📊 Shows progress with context passing
4. ✅ Returns final result

4. Deep Research Agent

Automated research with real-time streaming, web search, and citations using OpenAI or Gemini Deep Research APIs.

from praisonaiagents import DeepResearchAgent

# OpenAI Deep Research
agent = DeepResearchAgent(
    model="o4-mini-deep-research",  # or "o3-deep-research"
    verbose=True
)

result = agent.research("What are the latest AI trends in 2025?")
print(result.report)
print(f"Citations: {len(result.citations)}")

# Gemini Deep Research
from praisonaiagents import DeepResearchAgent

agent = DeepResearchAgent(
    model="deep-research-pro",  # Auto-detected as Gemini
    verbose=True
)

result = agent.research("Research quantum computing advances")
print(result.report)

Features:

• 🔍 Multi-provider support (OpenAI, Gemini, LiteLLM)
• 📡 Real-time streaming with reasoning summaries
• 📚 Structured citations with URLs
• 🛠️ Built-in tools: web search, code interpreter, MCP, file search
• 🔄 Automatic provider detection from model name

5. Query Rewriter Agent

Transform user queries to improve RAG retrieval quality using multiple strategies.

from praisonaiagents import QueryRewriterAgent, RewriteStrategy

agent = QueryRewriterAgent(model="gpt-4o-mini")

# Basic - expands abbreviations, adds context
result = agent.rewrite("AI trends")
print(result.primary_query)  # "What are the current trends in Artificial Intelligence?"

# HyDE - generates hypothetical document for semantic matching
result = agent.rewrite("What is quantum computing?", strategy=RewriteStrategy.HYDE)

# Step-back - generates broader context question
result = agent.rewrite("GPT-4 vs Claude 3?", strategy=RewriteStrategy.STEP_BACK)

# Sub-queries - decomposes complex questions
result = agent.rewrite("RAG setup and best embedding models?", strategy=RewriteStrategy.SUB_QUERIES)

# Contextual - resolves references using chat history
result = agent.rewrite("What about cost?", chat_history=[...])

Strategies:

• BASIC: Expand abbreviations, fix typos, add context
• HYDE: Generate hypothetical document for semantic matching
• STEP_BACK: Generate higher-level concept questions
• SUB_QUERIES: Decompose multi-part questions
• MULTI_QUERY: Generate multiple paraphrased versions
• CONTEXTUAL: Resolve references using conversation history
• AUTO: Automatically detect best strategy

6. Agent Memory (Zero Dependencies)

Enable persistent memory for agents - works out of the box without any extra packages.

from praisonaiagents import Agent
from praisonaiagents.memory import FileMemory

# Enable memory with a single parameter
agent = Agent(
    name="Personal Assistant",
    instructions="You are a helpful assistant that remembers user preferences.",
    memory=True,  # Enables file-based memory (no extra deps!)
    user_id="user123"  # Isolate memory per user
)

# Memory is automatically injected into conversations
result = agent.start("My name is John and I prefer Python")
# Agent will remember this for future conversations

Memory Types:

• Short-term: Rolling buffer of recent context (auto-expires)
• Long-term: Persistent important facts (sorted by importance)
• Entity: People, places, organizations with attributes
• Episodic: Date-based interaction history

Advanced Features:

from praisonaiagents.memory import FileMemory

memory = FileMemory(user_id="user123")

# Session Save/Resume
memory.save_session("project_session", conversation_history=[...])
memory.resume_session("project_session")

# Context Compression
memory.compress(llm_func=lambda p: agent.chat(p), max_items=10)

# Checkpointing
memory.create_checkpoint("before_refactor", include_files=["main.py"])
memory.restore_checkpoint("before_refactor", restore_files=True)

# Slash Commands
memory.handle_command("/memory show")
memory.handle_command("/memory save my_session")

Storage Options:

7. Rules & Instructions

PraisonAI auto-discovers instruction files from your project root and git root:

from praisonaiagents import Agent

# Agent auto-discovers CLAUDE.md, AGENTS.md, GEMINI.md, etc.
agent = Agent(name="Assistant", instructions="You are helpful.")
# Rules are injected into system prompt automatically

@Import Syntax:

# CLAUDE.md
See @README for project overview
See @docs/architecture.md for system design
@~/.praison/my-preferences.md

Rule File Format (with YAML frontmatter):

---
description: Python coding guidelines
globs: ["**/*.py"]
activation: always  # always, glob, manual, ai_decision
---

# Guidelines
- Use type hints
- Follow PEP 8

8. Auto-Generated Memories

from praisonaiagents.memory import FileMemory, AutoMemory

memory = FileMemory(user_id="user123")
auto = AutoMemory(memory, enabled=True)

# Automatically extracts and stores memories from conversations
memories = auto.process_interaction(
    "My name is John and I prefer Python for backend work"
)
# Extracts: name="John", preference="Python for backend"

9. Agentic Workflows

Create powerful multi-agent workflows with the Workflow class:

from praisonaiagents import Agent, Workflow

# Create agents
researcher = Agent(
    name="Researcher",
    role="Research Analyst",
    goal="Research topics thoroughly",
    instructions="Provide concise, factual information."
)

writer = Agent(
    name="Writer",
    role="Content Writer", 
    goal="Write engaging content",
    instructions="Write clear, engaging content based on research."
)

# Create workflow with agents as steps
workflow = Workflow(steps=[researcher, writer])

# Run workflow - agents process sequentially
result = workflow.start("What are the benefits of AI agents?")
print(result["output"])

Key Features:

• Agent-first - Pass Agent objects directly as workflow steps
• Pattern helpers - Use route(), parallel(), loop(), repeat()
• Planning mode - Enable with planning=True
• Callbacks - Monitor with on_step_complete, on_workflow_complete
• Async execution - Use workflow.astart() for async

Workflow Patterns (route, parallel, loop, repeat)

from praisonaiagents import Agent, Workflow
from praisonaiagents.workflows import route, parallel, loop, repeat

# 1. ROUTING - Classifier agent routes to specialized agents
classifier = Agent(name="Classifier", instructions="Respond with 'technical' or 'creative'")
tech_agent = Agent(name="TechExpert", role="Technical Expert")
creative_agent = Agent(name="Creative", role="Creative Writer")

workflow = Workflow(steps=[
    classifier,
    route({
        "technical": [tech_agent],
        "creative": [creative_agent]
    })
])

# 2. PARALLEL - Multiple agents work concurrently
market_agent = Agent(name="Market", role="Market Researcher")
competitor_agent = Agent(name="Competitor", role="Competitor Analyst")
aggregator = Agent(name="Aggregator", role="Synthesizer")

workflow = Workflow(steps=[
    parallel([market_agent, competitor_agent]),
    aggregator
])

# 3. LOOP - Agent processes each item
processor = Agent(name="Processor", role="Item Processor")
summarizer = Agent(name="Summarizer", role="Summarizer")

workflow = Workflow(
    steps=[loop(processor, over="items"), summarizer],
    variables={"items": ["AI", "ML", "NLP"]}
)

# 4. REPEAT - Evaluator-Optimizer pattern
generator = Agent(name="Generator", role="Content Generator")
evaluator = Agent(name="Evaluator", instructions="Say 'APPROVED' if good")

workflow = Workflow(steps=[
    generator,
    repeat(evaluator, until=lambda ctx: "approved" in ctx.previous_result.lower(), max_iterations=3)
])

# 5. CALLBACKS
workflow = Workflow(
    steps=[researcher, writer],
    on_step_complete=lambda name, r: print(f"✅ {name} done")
)

# 6. WITH PLANNING & REASONING
workflow = Workflow(
    steps=[researcher, writer],
    planning=True,
    reasoning=True
)

# 7. ASYNC EXECUTION
result = asyncio.run(workflow.astart("input"))

# 8. STATUS TRACKING
workflow.status  # "not_started" | "running" | "completed"
workflow.step_statuses  # {"step1": "completed", "step2": "skipped"}

from praisonaiagents.hooks import (
    HookRegistry, HookRunner, HookEvent, HookResult,
    BeforeToolInput
)

# Create a hook registry
registry = HookRegistry()

# Log all tool calls
@registry.on(HookEvent.BEFORE_TOOL)
def log_tools(event_data: BeforeToolInput) -> HookResult:
    print(f"Tool: {event_data.tool_name}")
    return HookResult.allow()

# Block dangerous operations
@registry.on(HookEvent.BEFORE_TOOL)
def security_check(event_data: BeforeToolInput) -> HookResult:
    if "delete" in event_data.tool_name.lower():
        return HookResult.deny("Delete operations blocked")

17. Field Names Reference (A-I-G-S)

PraisonAI accepts both old (agents.yaml) and new (workflow.yaml) field names. Use the canonical names for new projects:

A-I-G-S Mnemonic - Easy to remember:

• Agents - Who does the work
• Instructions - How they behave
• Goal - What they achieve
• Steps - What they do

# Quick Reference - Canonical Format
name: My Workflow              # Workflow name (not 'topic')
agents:                        # Define agents (not 'roles')
  my_agent:
    role: Job Title            # Agent's role
    goal: What to achieve      # Agent's goal
    instructions: How to act   # Agent's behavior (not 'backstory')
    
steps:                         # Define steps (not 'tasks')
  - agent: my_agent
    action: What to do         # Step action (not 'description')

Note: The parser accepts both old and new names. Run praisonai workflow validate <file.yaml> to see suggestions for canonical names.

18. Extended agents.yaml with Workflow Patterns

Feature Parity: Both agents.yaml and workflow.yaml now support the same features:

• All workflow patterns (route, parallel, loop, repeat)
• All agent fields (function_calling_llm, max_rpm, max_execution_time, reflect_llm, templates)
• All step fields (expected_output, context, output_json, create_directory, callback)
• Framework support (praisonai, crewai, autogen)
• Process types (sequential, hierarchical, workflow)

You can use advanced workflow patterns directly in agents.yaml by setting process: workflow:

# agents.yaml with workflow patterns
framework: praisonai
process: workflow  # Enables workflow mode
topic: "Research AI trends"

workflow:
  planning: true
  reasoning: true
  verbose: true

variables:
  topic: AI trends

agents:  # Canonical: use 'agents' instead of 'roles'
  classifier:
    role: Request Classifier
    instructions: "Classify requests into categories"  # Canonical: use 'instructions' instead of 'backstory'
    goal: Classify requests
    
  researcher:
    role: Research Analyst
    instructions: "Expert researcher"  # Canonical: use 'instructions' instead of 'backstory'
    goal: Research topics
    tools:
      - tavily_search

steps:
  # Sequential step
  - agent: classifier
    action: "Classify: {{topic}}"
    
  # Route pattern - decision-based branching
  - name: routing
    route:
      technical: [tech_expert]
      default: [researcher]
      
  # Parallel pattern - concurrent execution
  - name: parallel_research
    parallel:
      - agent: researcher
        action: "Research market trends"
      - agent: researcher
        action: "Research competitors"
        
  # Loop pattern - iterate over items
  - agent: researcher
    action: "Analyze {{item}}"
    loop:
      over: topics
      
  # Repeat pattern - evaluator-optimizer
  - agent: aggregator
    action: "Synthesize findings"
    repeat:
      until: "comprehensive"
      max_iterations: 3

Run with the same simple command:

praisonai agents.yaml

19. MCP (Model Context Protocol)

# stdio - Local NPX/Python servers
agent = Agent(tools=MCP("npx @modelcontextprotocol/server-memory"))

# Streamable HTTP - Production servers
agent = Agent(tools=MCP("https://api.example.com/mcp"))

# WebSocket - Real-time bidirectional
agent = Agent(tools=MCP("wss://api.example.com/mcp", auth_token="token"))

# SSE (Legacy) - Backward compatibility
agent = Agent(tools=MCP("http://localhost:8080/sse"))

# With environment variables
agent = Agent(
    tools=MCP(
        command="npx",
        args=["-y", "@modelcontextprotocol/server-brave-search"],
        env={"BRAVE_API_KEY": "your-key"}
    )
)

# Multiple MCP servers + regular functions
def my_custom_tool(query: str) -> str:
    """Custom tool function."""
    return f"Result: {query}"

agent = Agent(
    name="MultiToolAgent",
    instructions="Agent with multiple MCP servers",
    tools=[
        MCP("uvx mcp-server-time"),                    # Time tools
        MCP("npx @modelcontextprotocol/server-memory"), # Memory tools
        my_custom_tool                                  # Regular function
    ]
)

MCP Server (Expose Tools as MCP Server)

Expose your Python functions as MCP tools for Claude Desktop, Cursor, and other MCP clients:

from praisonaiagents.mcp import ToolsMCPServer

def search_web(query: str, max_results: int = 5) -> dict:
    """Search the web for information."""
    return {"results": [f"Result for {query}"]}

def calculate(expression: str) -> dict:
    """Evaluate a mathematical expression."""
    return {"result": eval(expression)}

# Create and run MCP server
server = ToolsMCPServer(name="my-tools")
server.register_tools([search_web, calculate])
server.run()  # stdio for Claude Desktop
# server.run_sse(host="0.0.0.0", port=8080)  # SSE for web clients

PraisonAI supports the A2A Protocol for agent-to-agent communication, enabling your agents to be discovered and collaborate with other AI agents.

A2A Server (Expose Agent as A2A Server)

from praisonaiagents import Agent, A2A
from fastapi import FastAPI

# Create an agent with tools
def search_web(query: str) -> str:
    """Search the web for information."""
    return f"Results for: {query}"

agent = Agent(
    name="Research Assistant",
    role="Research Analyst",
    goal="Help users research topics",
    tools=[search_web]
)

# Expose as A2A Server
a2a = A2A(agent=agent, url="http://localhost:8000/a2a")

app = FastAPI()
app.include_router(a2a.get_router())

# Run: uvicorn app:app --reload
# Agent Card: GET /.well-known/agent.json
# Status: GET /status

# With tools for context gathering
praisonai "latest AI trends" --expand-prompt --expand-tools tools.py

# Combine with query rewrite
praisonai "AI news" --query-rewrite --expand-prompt

Programmatic Usage

from praisonaiagents import PromptExpanderAgent, ExpandStrategy

# Basic usage
agent = PromptExpanderAgent()
result = agent.expand("write a movie script in 3 lines")
print(result.expanded_prompt)

# With specific strategy
result = agent.expand("blog about AI", strategy=ExpandStrategy.DETAILED)

# Available strategies: BASIC, DETAILED, STRUCTURED, CREATIVE, AUTO

100+ Models Support

PraisonAI supports 100+ LLM models from various providers. Visit our models documentation for the complete list.

📋 Agents Playbook

Simple Playbook Example

Create agents.yaml file and add the code below:

framework: praisonai
topic: Artificial Intelligence
agents:  # Canonical: use 'agents' instead of 'roles'
  screenwriter:
    instructions: "Skilled in crafting scripts with engaging dialogue about {topic}."  # Canonical: use 'instructions' instead of 'backstory'
    goal: Create scripts from concepts.
    role: Screenwriter
    tasks:
      scriptwriting_task:
        description: "Develop scripts with compelling characters and dialogue about {topic}."
        expected_output: "Complete script ready for production."

To run the playbook:

praisonai agents.yaml

🛠️ Custom Tools / Create Plugins

PraisonAI supports multiple ways to create and integrate custom tools (plugins) into your agents.

Using @tool Decorator

from praisonaiagents import Agent, tool

@tool
def search(query: str) -> str:
    """Search the web for information."""
    return f"Results for: {query}"

@tool
def calculate(expression: str) -> float:
    """Evaluate a math expression."""
    return eval(expression)

agent = Agent(
    instructions="You are a helpful assistant",
    tools=[search, calculate]
)
agent.start("Search for AI news and calculate 15*4")

Using BaseTool Class

from praisonaiagents import Agent, BaseTool

class WeatherTool(BaseTool):
    name = "weather"
    description = "Get current weather for a location"
    
    def run(self, location: str) -> str:
        return f"Weather in {location}: 72°F, Sunny"

agent = Agent(
    instructions="You are a weather assistant",
    tools=[WeatherTool()]
)
agent.start("What's the weather in Paris?")

Creating a Tool Package (pip installable)

# pyproject.toml
[project]
name = "my-praisonai-tools"
version = "1.0.0"
dependencies = ["praisonaiagents"]

[project.entry-points."praisonaiagents.tools"]
my_tool = "my_package:MyTool"

# my_package/__init__.py
from praisonaiagents import BaseTool

class MyTool(BaseTool):
    name = "my_tool"
    description = "My custom tool"
    
    def run(self, param: str) -> str:
        return f"Result: {param}"

After pip install, tools are auto-discovered:

agent = Agent(tools=["my_tool"])  # Works automatically!

🧠 Memory & Context

PraisonAI provides zero-dependency persistent memory for agents. For detailed examples, see section 6. Agent Memory in the Python Code Examples.

📚 Knowledge & Retrieval (RAG)

PraisonAI provides a complete knowledge stack for building RAG applications with multiple vector stores, retrieval strategies, rerankers, and query modes.

RAG Quickstart (Agent-first)

from praisonaiagents import Agent
from praisonaiagents.rag.models import RetrievalStrategy

# Agent with RAG - simplest approach
agent = Agent(
    name="Research Assistant",
    knowledge=["docs/manual.pdf", "data/faq.txt"],
    knowledge_config={"vector_store": {"provider": "chroma"}},
    rag_config={
        "include_citations": True,
        "retrieval_strategy": RetrievalStrategy.HYBRID,  # Dense + BM25
        "rerank": True,
    }
)

# Query with citations
result = agent.rag_query("How do I authenticate?")
print(result.answer)
for citation in result.citations:
    print(f"  [{citation.id}] {citation.source}")

RAG CLI Commands

RAG CLI Examples

# Query with hybrid retrieval (dense + BM25 keyword search)
praisonai rag query "What are the key findings?" --hybrid

# Query with hybrid + reranking for best quality
praisonai rag query "Summarize conclusions" --hybrid --rerank

# Interactive chat with hybrid retrieval
praisonai rag chat --collection research --hybrid --rerank

# Start API server with OpenAI-compatible endpoint
praisonai rag serve --hybrid --rerank --openai-compat --port 8080

# Query with profiling
praisonai rag query "Summary?" --profile --profile-out ./profile.json

Knowledge CLI Commands

Knowledge CLI Examples

# Index documents
praisonai knowledge index ./docs/ --collection myproject

# Search with hybrid retrieval
praisonai knowledge search "authentication" --hybrid --collection myproject

# Index with profiling
praisonai knowledge index ./data --profile --profile-out ./profile.json

Knowledge vs RAG vs AutoRagAgent

• Knowledge is the indexing and retrieval substrate - use for indexing and raw search
• RAG orchestrates on top - use for question answering with LLM-generated responses and citations
• AutoRagAgent wraps an Agent with automatic retrieval decision - use when you want the agent to decide when to retrieve
• All share the same underlying index

AutoRagAgent (Automatic RAG)

AutoRagAgent automatically decides when to retrieve context from knowledge bases vs direct chat, based on query heuristics.

from praisonaiagents import Agent, AutoRagAgent

# Create agent with knowledge
agent = Agent(
    name="Research Assistant",
    knowledge=["docs/manual.pdf"],
    user_id="user123",  # Required for RAG retrieval
)

# Wrap with AutoRagAgent
auto_rag = AutoRagAgent(
    agent=agent,
    retrieval_policy="auto",  # auto, always, never
    top_k=5,
    hybrid=True,
    rerank=True,
)

# Auto-decides: retrieves for questions, skips for greetings
result = auto_rag.chat("What are the key findings?")  # Retrieves
result = auto_rag.chat("Hello!")  # Skips retrieval

# Force retrieval or skip per-call
result = auto_rag.chat("Hi", force_retrieval=True)
result = auto_rag.chat("Summary?", skip_retrieval=True)

CLI Usage:

# Enable auto-rag with default policy (auto)
praisonai --auto-rag "What are the key findings?"

# Always retrieve
praisonai --auto-rag --rag-policy always "Tell me about X"

# With hybrid retrieval and reranking
praisonai --auto-rag --rag-hybrid --rag-rerank "Summarize the document"

Configuration Precedence

Settings are applied in this order (highest priority first):

1. CLI flags - --hybrid, --rerank, --top-k
2. Environment variables - PRAISONAI_HYBRID=true
3. Config file - YAML configuration (--config)
4. Defaults

# Environment variables
export PRAISONAI_HYBRID=true
export PRAISONAI_RERANK=true
export PRAISONAI_TOP_K=10

Lightweight Installs

# Base install (minimal, fast imports)
pip install praisonaiagents

# With RAG API server support
pip install "praisonai[rag-api]"

Live Tests (Real API Keys)

Run integration tests with real API keys:

# Enable live tests
export PRAISONAI_LIVE_TESTS=1
export OPENAI_API_KEY="your-key"

# Run live tests
pytest -m live tests/integration/
