1. Project Overview

OxyGent is an open-source framework that unifies tools, models, and agents into modular Oxy. Empowering developers with transparent, end-to-end pipelines, OxyGent makes building, running, and evolving multi-agent systems seamless and infinitely extensible.

1. Core Features

🏎️ Efficient Development

• OxyGent is a modular multi-agent framework that lets you build, deploy, and evolve AI teams with unprecedented efficiency. Its standardized Oxy components snap together like LEGO bricks, enabling rapid assembly of agents while supporting hot-swapping and cross-scenario reuse - all through clean Python interfaces without messy configs.

🤝 Intelligent Collaboration

• The framework supercharges collaboration with dynamic planning paradigms, where agents intelligently decompose tasks, negotiate solutions, and adapt to changes in real-time. Unlike rigid workflow systems, OxyGent's agents handle emergent challenges naturally while maintaining full auditability of every decision.

🕸️ Elastic Architecture

• Under the hood, an elastic architecture supports any agent topology- from simple ReAct to complex hybrid planning patterns. Automated dependency mapping and visual debugging tools make it easy to optimize performance across distributed systems.

🔁 Continuous Evolution

• Every interaction becomes a learning opportunity - thanks to built-in evaluation engines that auto-generate training data. Your agents continuously improve through knowledge feedback loops while maintaining full transparency.

📈 Scalability

• Scaling follows Metcalfe's Law- OxyGent's distributed scheduler enables linear cost growth while delivering exponential gains in collaborative intelligence. The system effortlessly handles domain-wide optimization and real-time decision making at any scale.

The latest version of OxyGent (July 15, 2025) in the GAIA get 59.14 points, and current top opensource system OWL gets 60.8 points.

1. Quick Start

Step 1: Create and activate a python environment

Method 1:

conda

conda create -n oxy_env python==3.10

conda activate oxy_env

Method 2:

uv

curl -LsSf https://astral.sh/uv/install.sh | sh

uv python install 3.10

uv venv .venv --python 3.10

source .venv/bin/activate

Step 2: Install the required python package

Method 1:

conda

pip install oxygent

Method 2:

uv

uv pip install oxygent

Method 3:

set develop environment

git clone https://github.com/jd-opensource/OxyGent.git

cd OxyGent

pip install -r requirements.txt # or in uv

brew install coreutils # maybe essential

Step 3: Node.js Environment (if using MCP)

• Download and install Node.js

Step 4: Write a sample python script

import os from oxygent import MAS , Config , oxy , preset_tools

• demo.py

Config . set_agent_llm_model ( "default_llm" )

oxy_space = [ oxy . HttpLLM ( name = "default_llm" , api_key = os . getenv ( "DEFAULT_LLM_API_KEY" ), base_url = os . getenv ( "DEFAULT_LLM_BASE_URL" ), model_name = os . getenv ( "DEFAULT_LLM_MODEL_NAME" ), ), preset_tools . time_tools , oxy .

ReActAgent ( name = "time_agent" , desc = "A tool that can query the time" , tools = [ "time_tools" ], ), preset_tools . file_tools , oxy .

ReActAgent ( name = "file_agent" , desc = "A tool that can operate the file system" , tools = [ "file_tools" ], ), preset_tools . math_tools , oxy . ReActAgent ( name = "math_agent" , desc = "A tool that can perform mathematical calculations.

" , tools = [ "math_tools" ], ), oxy . ReActAgent ( is_master = True , name = "master_agent" , sub_agents = [ "time_agent" , "file_agent" , "math_agent" ], ), ]

async def main (): async with MAS ( oxy_space = oxy_space ) as mas : await mas . start_web_service ( first_query = "What time is it now? Please save it into time.txt." )

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

Step 5

Set Environment Variables

• Method 1: Declare in terminal

export DEFAULT_LLM_API_KEY= " your_api_key "

export DEFAULT_LLM_BASE_URL= " your_base_url "

export DEFAULT_LLM_MODEL_NAME= " your_model_name "

DEFAULT_LLM_API_KEY= " your_api_key " DEFAULT_LLM_BASE_URL= " your_base_url " DEFAULT_LLM_MODEL_NAME= " your_model_name "

• Method 2: Create a .env file

Step 6: Run the example

• Start the multi-agent system

python demo.py

Step 7: View the output

FAQ

General Questions

What is OxyGent? OxyGent is an open-source framework that unifies tools, models, and agents into modular Oxy components. It empowers developers to build, run, and evolve multi-agent systems with transparent, end-to-end pipelines.

How is OxyGent different from other multi-agent frameworks? OxyGent uses a unique "Oxy" abstraction that standardizes agent components, enabling hot-swapping and cross-scenario reuse.

Unlike rigid workflow systems, OxyGent supports dynamic planning paradigms where agents intelligently decompose tasks and adapt to changes in real-time.

What is the Oxy abstraction? Oxy is a standardized component model that snaps together like LEGO bricks. Each Oxy encapsulates a specific capability (tool, model, or agent) with clean Python interfaces, enabling rapid assembly and evolution of AI teams.

Setup & Configuration

What are the system requirements?

Python 3.10+

pip package manager

• API key from an LLM provider (OpenAI, Anthropic, etc.)

How do I install OxyGent?

pip install oxygent

Can I use OxyGent with local models? Yes! OxyGent supports any LLM provider that exposes a compatible API. Configure your local model via environment variables ( DEFAULT_LLM_BASE_URL , DEFAULT_LLM_MODEL_NAME ).

Agent Development

How do I create a custom Oxy? Create a new class that inherits from the base Oxy class and implement the required methods. See the documentation for detailed guides.

What planning paradigms does OxyGent support? OxyGent supports multiple planning paradigms:

• ReAct : Reasoning + Acting pattern for simple tasks

• Dynamic Planning : Agents intelligently decompose tasks and negotiate solutions

• Hybrid Planning : Combines multiple paradigms for complex scenarios

How does OxyGent handle agent collaboration? OxyGent's elastic architecture supports any agent topology. Agents communicate through standardized interfaces, with automated dependency mapping and visual debugging tools for optimization.

Deployment

How do I deploy OxyGent applications? OxyGent applications can be deployed as standard Python applications:

• Local Development : Run python demo.py for local testing

• Production : Use the distributed scheduler for scaling across multiple nodes

Docker : Containerize your OxyGent application for consistent deployment

Is OxyGent suitable for enterprise use? Yes! OxyGent is designed for enterprise scenarios with features like:

• Distributed scheduling for horizontal scaling

• Full auditability of every decision

• Built-in evaluation engines for continuous improvement

• Support for domain-wide optimization and real-time decision making

Troubleshooting

Common Issues:

• Import Errors : Ensure Python 3.10+ is installed and dependencies are up to date

• API Key Errors : Verify your LLM provider API key is correctly configured

• Agent Communication Issues : Check that all Oxy components are properly registered

Where can I get help?
