Agent with Storage

Persist a Nebius agent's chat history to Postgres with add_history_to_context for multi-turn context.

Code

import os

from agno.agent import Agent
from agno.db.postgres import PostgresDb
from agno.models.nebius import Nebius
from agno.tools.websearch import WebSearchTools

# Setup the database
db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"
db = PostgresDb(db_url=db_url)

agent = Agent(
    model=Nebius(id=os.environ["NEBIUS_MODEL_ID"]),
    db=db,
    tools=[WebSearchTools()],
    add_history_to_context=True,
)
agent.print_response("How many people live in Canada?")
agent.print_response("What is their national anthem called?")

Select a text-generation model with function-calling support for this example.
