Usage

You have to pass your API key for authentification. Visit the page https://platform.openai.com/account/api-keys to retrieve the API Key you'll use in your requests. Supposed in the below demo that the key is stored in the environment file.

import { ChatGPTApi } from "chatgpt-api-client";

async function try() {
    const api = new ChatGPTApi({ apiKey: process.env.OPENAI_API_KEY });
    const response = await api.sendMessage({ prompt: "Hi! How is the weather today?" });
    console.info(response);
}

For users who belong to multiple organizations, you can pass a this property to specify which organization is used for an API request.

const api = new ChatGPTApi({ apiKey: process.env.OPENAI_API_KEY, organization: "custom-org" });

You can specify which AI model will be used in the processing of your requests.

const response = await api.sendMessage({ model: "model-id-0", prompt: "Hi! How is the weather today?" });

text-davinci-003 is the default model that is specified in case of non-mentioned model property.

There are a bit of parameters to pass in the sendMessage function namely the max of tokens, temperature and number of completions.

const response = await api.sendMessage({ 
        prompt: "Hi! How is the weather today?", //The prompt(s) to generate completions for
        model: "text-davinci-003", //ID of the model to use
        max_tokens: 500, //The maximum number of tokens to generate in the completion
        temperature: 0, //What sampling temperature to use, between 0 and 2, Default is 1
        nCompeletions: 3 //How many completions to generate for each prompt. Default is 1
    });

const api = new ChatGPTApi({ apiKey: process.env.OPENAI_API_KEY });
//Retrieve the list of available OpenAI models
let models = await api.getModels();

Usage with Promise return

The previous examples were made with Async/Await calls through asynchronos promise. We could explicitly handle the return of Promise Object.

api.sendMessage({ prompt: "Hello! this is a test" }).then((response) => {
    //Proceed with success
    console.info("Response data", response);
}, error => {
    //An error has occured
    console.error("Error", error);
});

For Common.JS usage

const { ChatGPTApi } = require("chatgpt-api-client");
