BeeAI Framework for Python

Build production-ready multi-agent systems. Also available in TypeScript.

What is BeeAI Framework?

BeeAI Framework is a comprehensive toolkit for building intelligent, autonomous agents and multi-agent systems. It provides everything you need to create agents that can reason, take actions, and collaborate to solve complex problems.

[!TIP] Get started quickly with the beeai-framework-py-starter template.

Key Features

Feature	Description
🤖 Agents	Create intelligent agents that can reason, act, and adapt
🔄 Workflows	Orchestrate multi-agent systems with complex execution flows
🔌 Backend	Connect to any LLM provider with unified interfaces
🔧 Tools	Extend agents with web search, weather, code execution, and more
🔍 RAG	Build retrieval-augmented generation systems with vector stores and document processing
📝 Templates	Build dynamic prompts with enhanced Mustache syntax
🧠 Memory	Manage conversation history with flexible memory strategies
📊 Observability	Monitor agent behavior with events, logging, and robust error handling
🚀 Serve	Host agents in servers with support for multiple protocols such as A2A and MCP
💾 Cache	Optimize performance and reduce costs with intelligent caching
💿 Serialization	Save and load agent state for persistence across sessions

Quick Start

Prerequisite

✅ Python >= 3.11

Installation

pip install beeai-framework

Multi-Agent Example

import asyncio

from beeai_framework.agents.requirement import RequirementAgent
from beeai_framework.agents.requirement.requirements.conditional import ConditionalRequirement
from beeai_framework.backend import ChatModel
from beeai_framework.errors import FrameworkError
from beeai_framework.middleware.trajectory import GlobalTrajectoryMiddleware
from beeai_framework.tools import Tool
from beeai_framework.tools.handoff import HandoffTool
from beeai_framework.tools.search.wikipedia import WikipediaTool
from beeai_framework.tools.think import ThinkTool
from beeai_framework.tools.weather import OpenMeteoTool


async def main() -> None:
    knowledge_agent = RequirementAgent(
        llm=ChatModel.from_name("ollama:granite4:micro"),
        tools=[ThinkTool(), WikipediaTool()],
        requirements=[ConditionalRequirement(ThinkTool, force_at_step=1)],
        role="Knowledge Specialist",
        instructions="Provide answers to general questions about the world.",
    )

    weather_agent = RequirementAgent(
        llm=ChatModel.from_name("ollama:granite4:micro"),
        tools=[OpenMeteoTool()],
        role="Weather Specialist",
        instructions="Provide weather forecast for a given destination.",
    )

    main_agent = RequirementAgent(
        name="MainAgent",
        llm=ChatModel.from_name("ollama:granite4:micro"),
        tools=[
            ThinkTool(),
            HandoffTool(
                knowledge_agent,
                name="KnowledgeLookup",
                description="Consult the Knowledge Agent for general questions.",
            ),
            HandoffTool(
                weather_agent,
                name="WeatherLookup",
                description="Consult the Weather Agent for forecasts.",
            ),
        ],
        requirements=[ConditionalRequirement(ThinkTool, force_at_step=1)],
        # Log all tool calls to the console for easier debugging
        middlewares=[GlobalTrajectoryMiddleware(included=[Tool])],
    )

    question = "If I travel to Rome next weekend, what should I expect in terms of weather, and also tell me one famous historical landmark there?"
    print(f"User: {question}")

    try:
        response = await main_agent.run(question, expected_output="Helpful and clear response.")
        print("Agent:", response.last_message.text)
    except FrameworkError as err:
        print("Error:", err.explain())


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

Message Content Helpers (Text / Image / File)

You can build multimodal user messages with simple factory helpers:

from beeai_framework.backend import UserMessage

# Plain text
msg_text = UserMessage.from_text("Explain the solar eclipse")

# Image (data URI or URL)
msg_image = UserMessage.from_image("data:image/png;base64,iVBORw0KGgoAAA...")

# File (either file_id OR file_data)
msg_file = UserMessage.from_file(
    file_id="https://example.com/sample.pdf",
    format="application/pdf",
)

# Inline base64 file
msg_inline_pdf = UserMessage.from_file(
    file_data="data:application/pdf;base64,AAA...",
    format="application/pdf",
)

The file message API is now flattened (no nested file={...} structure). Use file_id for remote/previously uploaded resources or file_data for a data URI.
