Multi-turn Conversation (Interactions)

Persist previous_interaction_id across turns with a database so GeminiInteractions keeps context server-side.

The Interactions API keeps conversation history server-side. After the first turn, the model sends only the new message and references the prior turn via previous_interaction_id. Multi-turn needs a database so the interaction ID from each response is persisted and read back on the next turn.

Code

multi_turn.py

from agno.agent import Agent
from agno.db.sqlite import SqliteDb
from agno.models.google import GeminiInteractions

agent = Agent(
    model=GeminiInteractions(id="gemini-3.5-flash"),
    add_history_to_context=True,
    db=SqliteDb(db_file="tmp/data.db"),
    markdown=True,
)

if __name__ == "__main__":
    # First turn - establishes the interaction
    agent.print_response("My name is Alice and I love hiking in the mountains.")

    # Second turn - references the previous interaction for context
    agent.print_response("What did I just tell you about myself?")

    # Third turn - continues the conversation chain
    agent.print_response(
        "Suggest a hiking destination based on what you know about me."
    )
