Set Client

Pass a custom ollama.Client instance to Ollama via the client parameter.

Code

from agno.agent import Agent, RunOutput  # noqa
from agno.models.ollama import Ollama
from ollama import Client as OllamaClient

agent = Agent(
    model=Ollama(id="llama3.1:8b", client=OllamaClient(host="http://localhost:11434")),
    markdown=True,
)

# Print the response in the terminal
agent.print_response("Share a 2 sentence horror story")

Usage

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Start the local Ollama service

Install Ollama and start its desktop app or service on http://localhost:11434. If you start it manually with ollama serve, keep that process running in a separate terminal.

In the terminal where you will pull models and run Python, select that server and clear the direct-cloud key. The native Ollama client also reads this key independently of Agno.

export OLLAMA_HOST=http://localhost:11434
unset OLLAMA_API_KEY

Pull the model

ollama pull llama3.1:8b

Install dependencies

uv pip install -U ollama agno

Run Agent

Save the code above as set_client.py, then run:

python set_client.py
