# Change State on Run

> Pass a user's name and age into session state at run time and keep the values isolated per session and user.

Set session state when you run the agent, with different values for different users and sessions. State persists within a session but stays isolated between sessions and users.

<Steps>
  <Step title="Create a Python file">
    ```python change_state_on_run.py theme={null}
    from agno.agent import Agent
    from agno.db.in_memory import InMemoryDb
    from agno.models.openai import OpenAIResponses

    agent = Agent(
        db=InMemoryDb(),
        model=OpenAIResponses(id="gpt-5.2"),
        instructions="Users name is {user_name} and age is {age}",
        debug_mode=True,
    )

    # Sets the session state for the session with the id "user_1_session_1"
    agent.print_response(
        "What is my name?",
        session_id="user_1_session_1",
        user_id="user_1",
        session_state={"user_name": "John", "age": 30},
    )

    # Will load the session state from the session with the id "user_1_session_1"
    agent.print_response("How old am I?", session_id="user_1_session_1", user_id="user_1")

    # Sets the session state for the session with the id "user_2_session_1"
    agent.print_response(
        "What is my name?",
        session_id="user_2_session_1",
        user_id="user_2",
        session_state={"user_name": "Jane", "age": 25},
    )

    # Will load the session state from the session with the id "user_2_session_1"
    agent.print_response("How old am I?", session_id="user_2_session_1", user_id="user_2")
    ```
