Multiple Instances

Serve multiple Agno agents over AG-UI from one AgentOS with different prefixes.

Code

cookbook/05_agent_os/interfaces/agui/multiple_instances.py

from agno.agent.agent import Agent
from agno.db.sqlite import SqliteDb
from agno.models.openai import OpenAIResponses
from agno.os import AgentOS
from agno.os.interfaces.agui import AGUI
from agno.tools.websearch import WebSearchTools

db = SqliteDb(db_file="tmp/agentos.db")

chat_agent = Agent(
    name="Assistant",
    model=OpenAIResponses(id="gpt-5.4"),
    db=db,
    instructions="You are a helpful AI assistant.",
    add_datetime_to_context=True,
    markdown=True,
)

web_research_agent = Agent(
    name="Web Research Agent",
    model=OpenAIResponses(id="gpt-5.4"),
    db=db,
    tools=[WebSearchTools()],
    instructions="You are a helpful AI assistant that can search the web.",
    markdown=True,
)

agent_os = AgentOS(
    agents=[chat_agent, web_research_agent],
    interfaces=[
        AGUI(agent=chat_agent, prefix="/chat"),
        AGUI(agent=web_research_agent, prefix="/web-research"),
    ],
)
app = agent_os.get_app()

if __name__ == "__main__":
    agent_os.serve(app="multiple_instances:app", reload=True, port=9001)

Usage

1. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   
2. Set Environment Variables

   export OPENAI_API_KEY=your_openai_api_key
   
3. Install Dependencies

   uv pip install 'agno[agui]' ddgs
   
4. Run Example

   python cookbook/05_agent_os/interfaces/agui/multiple_instances.py
   

Key Features

• Multiple Endpoints: Each AGUI(prefix=...) mounts its own {prefix}/agui endpoint
• Shared AgentOS: Two agents served from a single app
• Per-Agent Tools: The web research agent has WebSearchTools; the chat agent does not
• Shared Database: Both agents use the same SqliteDb
