Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno "psycopg[binary]" ddgs openai sqlalchemy

Export your Nebius API key

export NEBIUS_API_KEY="your_nebius_api_key_here"

Run PgVector

docker run -d \
  -e POSTGRES_DB=ai \
  -e POSTGRES_USER=ai \
  -e POSTGRES_PASSWORD=ai \
  -e PGDATA=/var/lib/postgresql \
  -v pgvolume:/var/lib/postgresql \
  -p 5532:5432 \
  --name pgvector \
  agnohq/pgvector:18

Select an enabled Token Factory model

Copy a model ID available to your account for https://api.tokenfactory.nebius.com/v1 from the Token Factory console. For knowledge and tool examples it must support function calling; for structured output it must support JSON Schema. Confirm the endpoint and model's access before running.

export NEBIUS_MODEL_ID="your-enabled-model-id"

Replace the placeholder with your copied model ID. Add from os import environ to the saved file, then set every model construction to Nebius(id=environ["NEBIUS_MODEL_ID"]). Keep any additional model options. The adapter's default ID does not establish which models your account can access. A dedicated deployment must instead use the model and endpoint supplied for that deployment, with an explicit base_url.

Run the example

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

python db.py
