Building Teams

Define team members, roles, and structure for multi-agent coordination.

Start simple: a model, team members, and instructions. Add functionality as needed.

Minimal Example

research_team.py

from agno.team import Team
from agno.agent import Agent
from agno.models.openai import OpenAIResponses
from agno.tools.hackernews import HackerNewsTools
from agno.tools.yfinance import YFinanceTools

news_agent = Agent(
    name="News Agent",
    role="Get trending tech news from HackerNews",
    tools=[HackerNewsTools()]
)

finance_agent = Agent(
    name="Finance Agent",
    role="Get stock prices and financial data",
    tools=[YFinanceTools()]
)

team = Team(
    name="Research Team",
    members=[news_agent, finance_agent],
    model=OpenAIResponses(id="gpt-4o"),
    instructions="Delegate to the appropriate agent based on the request."
)

team.print_response("What are the trending AI stories and how is NVDA stock doing?", stream=True)

Team Modes

Teams default to coordinate mode (leader delegates and synthesizes). Set mode to change how the leader collaborates with members.

from agno.team.mode import TeamMode
from agno.models.openai import OpenAIResponses

team = Team(
    name="Language Router",
    members=[...],
    model=OpenAIResponses(id="gpt-4o"),
    mode=TeamMode.route
)

Mode	Configuration	Use case
Coordinate	mode=TeamMode.coordinate (default)	Decompose work, delegate to members, synthesize results
Route	mode=TeamMode.route	Route to a single specialist and return their response directly
Broadcast	mode=TeamMode.broadcast	Delegate the same task to all members and synthesize
Tasks	mode=TeamMode.tasks	Run a task list loop until the goal is complete

Tasks mode runs an iterative task loop. Use max_iterations to cap how many cycles the leader can run.

from agno.models.openai import OpenAIResponses

team = Team(
    name="Ops Team",
    members=[...],
    model=OpenAIResponses(id="gpt-4o"),
    mode=TeamMode.tasks,
    max_iterations=6
)

Team Members

Each member should have a name and role. The team leader uses these to decide who handles what.

news_agent = Agent(
    name="News Agent",                              # Identifies the agent
    role="Get trending tech news from HackerNews",  # Tells the leader what this agent does
    tools=[HackerNewsTools()]
)

For better tracing, also set an id:

news_agent = Agent(
    id="news-agent",
    name="News Agent",
    role="Get trending tech news from HackerNews",
    tools=[HackerNewsTools()]
)

When both id and name are set on a member, team delegation uses id as the member identifier.

Nested Teams

Teams can contain other teams. The top-level leader delegates to sub-team leaders, who delegate to their members.

from agno.team import Team
from agno.agent import Agent

team = Team(
    name="Language Team",
    members=[
        Agent(name="English Agent", role="Answer in English"),
        Agent(name="Chinese Agent", role="Answer in Chinese"),
        Team(
            name="Germanic Team",
            role="Handle German and Dutch questions",
            members=[
                Agent(name="German Agent", role="Answer in German"),
                Agent(name="Dutch Agent", role="Answer in Dutch"),
            ],
        ),
    ],
)

Model Inheritance

Team members inherit the model from their parent team if not explicitly set.

from agno.team import Team
from agno.agent import Agent
from agno.models.openai import OpenAIResponses
from agno.models.anthropic import Claude

# This agent uses its own model (Claude)
agent_with_model = Agent(
    name="Claude Agent",
    model=Claude(id="claude-sonnet-4-5"),
    role="Research with Claude"
)

# This agent inherits gpt-4o from the team
agent_without_model = Agent(
    name="Inherited Agent",
    role="Research with inherited model"
)

team = Team(
    name="Research Team",
    model=OpenAIResponses(id="gpt-4o"),  # Default for team and members without a model
    members=[agent_with_model, agent_without_model]
)

Callable Factories

Pass a function instead of a static list for members, tools, or knowledge. The function is called at the start of each run, so the composition can vary per user or session.

team_callable_members.py

from agno.agent import Agent
from agno.models.openai import OpenAIResponses
from agno.team import Team

writer = Agent(
    name="Writer",
    role="Content writer",
    model=OpenAIResponses(id="gpt-5-mini"),
    instructions=["Write clear, concise content."],
)

researcher = Agent(
    name="Researcher",
    role="Research analyst",
    model=OpenAIResponses(id="gpt-5-mini"),
    instructions=["Research topics and summarize findings."],
)


def pick_members(session_state: dict):
    if session_state.get("needs_research", False):
        return [researcher, writer]
    return [writer]


team = Team(
    name="Content Team",
    model=OpenAIResponses(id="gpt-5-mini"),
    members=pick_members,
    cache_callables=False,
)

team.print_response(
    "Write a haiku about Python",
    session_state={"needs_research": False},
    stream=True,
)

team.print_response(
    "Research the history of Python and write a short summary",
    session_state={"needs_research": True},
    stream=True,
)

The same pattern works for tools and knowledge. Agents also support callable factories for tools and knowledge.

Injected Parameters

Name your factory function parameters to receive context automatically:

Parameter	Type	Description
agent	Agent	The current Agent instance
team	Team	The current Team instance
run_context	RunContext	Run context with user_id, session_id, session_state
session_state	dict	Session state dict directly (defaults to {} if None)

Use any combination. A zero-argument factory also works.

add_tool and set_tools

add_tool() raises RuntimeError when tools is a callable factory. Use set_tools() to replace the factory entirely:

team = Team(tools=tools_for_user, ...)

team.add_tool(some_tool)              # raises RuntimeError

team.set_tools(new_factory)           # replace with a new factory
team.set_tools([DuckDuckGoTools()])   # replace with a static list

Callable Caching Settings

Factory results are cached by default. The cache key is resolved in this order: custom key function > user_id > session_id. If none are available, caching is skipped and the factory runs every time.

Setting	Default	Description
cache_callables	True	Enable or disable caching for all callable factories
callable_tools_cache_key	None	Custom cache key function for tools factory
callable_knowledge_cache_key	None	Custom cache key function for knowledge factory
callable_members_cache_key	None	Custom cache key function for members factory (Team only)

Set cache_callables=False when session_state changes between runs and the factory should re-evaluate each time.

Clear cached results programmatically:

from agno.utils.callables import clear_callable_cache

clear_callable_cache(team)                            # Clear all caches
clear_callable_cache(team, kind="tools")              # Clear tools cache only
clear_callable_cache(team, kind="tools", close=True)  # Clear and call .close() on cached resources

Use aclear_callable_cache() in async code.

Team Features

Teams support the same features as agents:

Feature	Description
Instructions	Guide the team leader on how to coordinate
Mode	Choose the coordination strategy (coordinate, route, broadcast, tasks)
Database	Persist session history and state
Reasoning	Enable the leader to plan before delegating
Knowledge	Give the leader access to a knowledge base
Memory	Store and recall information across sessions
Tools	Give the leader tools to use directly

See the guides below to add these features.
