Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno ollama

Select the local Ollama server

In the shell used for the pull commands and Python example, clear a previous cloud key and point native clients and embeddings at your local server:

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

Without this reset, OLLAMA_API_KEY makes Agno's default Ollama model route to https://ollama.com even when OLLAMA_HOST points locally. Keep a local Ollama server running for the following steps.

Prepare Ollama

Install and start Ollama, then pull the model used by this example:

ollama pull deepseek-r1:14b

Run the example

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

python demo_deepseek_r1.py
