Demo DeepSeek R1

Run the Ollama deepseek-r1:14b model to write and explain Python code for solving quadratic equations.

Code

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

agent = Agent(model=Ollama(host="http://localhost:11434", api_key=None, id="deepseek-r1:14b"), markdown=True)

# Print the response in the terminal
agent.print_response(
    "Write me python code to solve quadratic equations. Explain your reasoning."
)

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 deepseek-r1:14b

Install dependencies

uv pip install -U ollama agno

Run Agent

Save the code above as demo_deepseek_r1.py, then run:

python demo_deepseek_r1.py
