node-red-contrib-chatgpt-api

A Node-RED node for interacting with the OpenAI ChatGPT API.
Supports creating prompts, retrieving models, and generating AI-driven completions.

Features

- Easily interact with OpenAI's ChatGPT API for intelligent, chat-based completions.
- Customize model, temperature, and token limits.
- Requires an OpenAI API key: Get yours from the OpenAI Platform.
- Lightweight implementation using Node.js's native https module.

Installation

Install the nodes directly through Node-RED's built-in palette manager.

Nodes

- gptapi: Calls the ChatGPT API to generate completions
- gptprompt: Helps construct the prompt.
- gptmodels: Retrieves the list of available models from the OpenAI API.

Usage

1. Drag the gptapi node from the palette into your Node-RED workspace.
2. Double-click the node to open the configuration panel:
- Enter your OpenAI API Key. If you don’t have one, visit the OpenAI Platform to generate it.
- Specify a model in the node or in the input payload, e.g., gpt-4.
- Optionally set values for temperature and maximum tokens.
3. Use the gptmodels node to retrieve a list of available models.
4. Use the gptprompt node to configure a multi-part structured prompt and pass it to the gptapi node as msg.prompt.
5. The gptapi node returns the API response in msg.payload.
