  - name: primary-database
    type: bigquery
    key_path: /path/to/keyfile
    dataset: dataset-name
  - name: local
    type: duckdb
    key_path: None
    dataset: /path/to/local/files

models:
  - name: openai-4.1-mini
    vendor: openai
    model_ref: gpt-4.1-mini
    key_var: OPENAI_API_KEY
  - name: llama3.2
    vendor: ollama
    model_ref: llama3.2:latest
    api_url: http://localhost:11434/v1
