About open_prompt

Open Prompt Extension

The open_prompt() community extension is shamelessly inspired by the Motherduck prompt() but focused on self-hosted usage.

For examples and instructions check out the open_prompt() README

Configuration

Setup the completions API URL configuration w/ optional auth token and model name

SET VARIABLE openprompt_api_url = 'http://localhost:11434/v1/chat/completions';
SET VARIABLE openprompt_api_token = 'your_api_key_here';
SET VARIABLE openprompt_model_name = 'qwen2.5:0.5b';

Alternatively the following ENV variables can be used at runtime

OPEN_PROMPT_API_URL='http://localhost:11434/v1/chat/completions'
OPEN_PROMPT_API_TOKEN='your_api_key_here'
OPEN_PROMPT_MODEL_NAME='qwen2.5:0.5b'
OPEN_PROMPT_API_TIMEOUT='30'

For persistent usage, configure parameters using DuckDB SECRETS

CREATE PERSISTENT SECRET IF NOT EXISTS open_prompt (
      TYPE open_prompt,
      PROVIDER config,
      api_token 'your-api-token',
      api_url 'http://localhost:11434/v1/chat/completions',
      model_name 'qwen2.5:0.5b',
      api_timeout '30'
  );
