When we call Team.run(), it creates a stateless, singular Team run. But what if we want to continue this conversation i.e. have a multi-turn conversation? That’s where “Sessions” come in. A session is collection of consecutive runs. In practice, a session in the context of a Team is a multi-turn conversation between a user and the Team. Using a session_id, we can connect the conversation history and state across multiple runs. See more details in the Agent Sessions documentation.

​
Multi-user, multi-session Teams

Each user that is interacting with a Team gets a unique set of sessions and you can have multiple users interacting with the same Team at the same time. Set a user_id to connect a user to their sessions with the Team. In the example below, we set a session_id to demo how to have multi-turn conversations with multiple users at the same time.

Multi-user, multi-session example

from agno.team import Team
from agno.models.openai import OpenAIChat
from agno.db.sqlite import SqliteDb

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

team = Team(
    model=OpenAIChat(id="gpt-5-mini"),
    members=[
        Agent(name="Agent 1", role="You answer questions in English"),
        Agent(name="Agent 2", role="You answer questions in Chinese"),
        Agent(name="Agent 3", role="You answer questions in French"),
    ],
    db=db,
    respond_directly=True,
)

user_1_id = "user_101"
user_2_id = "user_102"

user_1_session_id = "session_101"
user_2_session_id = "session_102"

# Start the session with user 1 (This means "how are you?" in French)
team.print_response(
    "comment ça va?",
    user_id=user_1_id,
    session_id=user_1_session_id,
)
# Continue the session with user 1 (This means "tell me a joke" in French)
team.print_response("Raconte-moi une blague.", user_id=user_1_id, session_id=user_1_session_id)

# Start the session with user 2
team.print_response("Tell me about quantum physics.", user_id=user_2_id, session_id=user_2_session_id)
# Continue the session with user 2
agent.print_response("What is the speed of light?", user_id=user_2_id, session_id=user_2_session_id)

# Ask the agent to give a summary of the conversation, this will use the history from the previous messages (but only for user 1)
agent.print_response(
    "Give me a summary of our conversation.",
    user_id=user_2_id,
    session_id=user_2_session_id,
)

Session Summaries

The Team can store a condensed representations of the session, useful when chat histories gets too long. This is called a “Session Summary” in Agno. To enable session summaries, set enable_session_summaries=True on the Team.

Session summary example

session_summary.py
    from agno.team import Team
    from agno.models.google.gemini import Gemini
    from agno.db.sqlite import SqliteDb

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

    user_id = "jon_hamm@example.com"
    session_id = "1001"

    team = Team(
        model=Gemini(id="gemini-2.0-flash-001"),
        members=[
            Agent(name="Agent 1", role="You answer questions in English"),
            Agent(name="Agent 2", role="You answer questions in Chinese"),
        ],
        db=db,
        enable_session_summaries=True,
    )

    team.print_response(
        "What can you tell me about quantum computing?",
        stream=True,
        user_id=user_id,
        session_id=session_id,
    )

    team.print_response(
        "I would also like to know about LLMs?",
        stream=True,
        user_id=user_id,
        session_id=session_id
    )

    session_summary = team.get_session_summary(session_id=session_id)
    print(f"Session summary: {session_summary.summary}")

​
Customize Session Summaries

You can adjust the session summaries by providing a custom session_summary_prompt to the Team. The SessionSummaryManager class is responsible for handling the model used to create and update session summaries. You can adjust it to personalize how summaries are created and updated: 
from agno.team import Team
from agno.session import SessionSummaryManager
from agno.models.openai import OpenAIChat
from agno.db.sqlite import SqliteDb

# Setup your database
db = SqliteDb(db_file="agno.db")

# Setup your Session Summary Manager, to adjust how summaries are created
session_summary_manager = SessionSummaryManager(
    # Select the model used for session summary creation and updates. If not specified, the agent's model is used by default.
    model=OpenAIChat(id="gpt-5-mini"),
    # You can also overwrite the prompt used for session summary creation
    session_summary_prompt="Create a very succinct summary of the following conversation:",
)

# Now provide the adjusted Memory Manager to your Agent
team = Team(
  members=[],
  db=db,
  session_summary_manager=session_summary_manager,
  enable_session_summaries=True,
)

​
Session history

Teams with storage enabled automatically have access to the message and run history of the session. You can access these messages using:
  • agent.get_messages_for_session() -> Gets access to all the messages for the session, for the current agent.
  • agent.get_chat_history() -> Gets access to all the unique messages for the session.
We can give the Agent access to the chat history in the following ways:
  • We can set add_history_to_context=True and num_history_runs=5 to add the messages from the last 5 runs automatically to every message sent to the agent.
  • We can set read_chat_history=True to provide a get_chat_history() tool to your agent allowing it to read any message in the entire chat history.
  • We recommend setting all 3: add_history_to_context=True, num_history_runs=3 and read_chat_history=True for the best experience.
  • We can also set read_tool_call_history=True to provide a get_tool_call_history() tool to your agent allowing it to read tool calls in reverse chronological order.
Take a look at this example:

Session history example

session_history.py
from agno.agent import Agent
from agno.models.google.gemini import Gemini
from agno.db.sqlite import SqliteDb

agent = Agent(
    model=Gemini(id="gemini-2.0-flash-exp"),
    db=SqliteDb(db_file="tmp/data.db"),
    add_history_to_context=True,
    num_history_runs=3,
    read_chat_history=True,
    description="You are a helpful assistant that always responds in a polite, upbeat and positive manner.",
)

agent.print_response("Share a 2 sentence horror story", stream=True)

agent.print_response("What was my first message?", stream=True)

​
Search the session history

In some scenarios, you might want to fetch messages from across multiple sessions to provide context or continuity in conversations. To enable fetching messages from the last N sessions, you need to use the following flags:
  • search_session_history: Set this to True to allow searching through previous sessions.
  • num_history_sessions: Specify the number of past sessions to include in the search. In the example below, it is set to 2 to include only the last 2 sessions.
It’s advisable to keep this number low (2 or 3), as a larger number might fill up the context length of the model, potentially leading to performance issues. Here’s an example of searching through the last 2 sessions: 
# Remove the tmp db file before running the script
import os

from agno.team import Team
from agno.models.openai import OpenAIChat
from agno.db.sqlite import SqliteDb

os.remove("tmp/data.db")

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

team = Team(
    members=[
      Agent(name="Agent 1", role="You answer questions in English"),
      Agent(name="Agent 2", role="You answer questions in Chinese"),
    ],
    model=OpenAIChat(id="gpt-5-mini"),
    user_id="user_1",
    db=db,
    search_session_history=True,  # allow searching previous sessions
    num_history_sessions=2,  # only include the last 2 sessions in the search to avoid context length issues
)

session_1_id = "session_1_id"
session_2_id = "session_2_id"
session_3_id = "session_3_id"
session_4_id = "session_4_id"
session_5_id = "session_5_id"

team.print_response("What is the capital of South Africa?", session_id=session_1_id)
team.print_response("What is the capital of China?", session_id=session_2_id)
team.print_response("What is the capital of France?", session_id=session_3_id)
team.print_response("What is the capital of Japan?", session_id=session_4_id)
team.print_response(
    "What did I discuss in my previous conversations?", session_id=session_5_id
)  # It should only include information from the last 2 sessions
