source .venv/bin/activate
2

Set your API key

export CEREBRAS_API_KEY=xxx
3

Install libraries

pip install -U agno cerebras-cloud-sdk
4

Start your Postgres server

Ensure your Postgres server is running and accessible at the connection string used in db_url.

5

Run Agent (first time)

The first run will load and index the PDF. This may take a while.

python cookbook/models/cerebras/basic_knowledge.py

Subsequent Runs

After the first run, comment out or remove knowledge_base.load(recreate=True) to avoid reloading the PDF each time.
