The most common use case is that of text-to-image where the user sends a prompt which the image model processes and returns an image.
The guide for vision models is available here.

Text-to-Image Usage

Portkey supports the OpenAI signature to make text-to-image requests. 
import Portkey from 'portkey-ai';

// Initialize the Portkey client
const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY",  // Replace with your Portkey API key
    virtualKey: "VIRTUAL_KEY"   // Add your provider's virtual key
});

async function main() {
  const image = await portkey.images.generate({
    model: "dall-e-3",
    prompt: "Lucy in the sky with diamonds"
  });

  console.log(image.data);
}

main();

API Reference

Create Image On completion, the request will get logged in the logs UI where the image can be viewed. (Note that providers may remove the hosted image after a period of time, so some logs might only contain the url)

Cookbook

Here’s a detailed cookbook on image generation using Portkey which demonstrates the use of multiple providers and routing between them through Configs.
