Quickstart

Get started by following our API guide or jump right into the example of using the Gen-4 Image References model below:

Node

import RunwayML, { TaskFailedError } from '@runwayml/sdk';

const client = new RunwayML();

try {
  // Create a new image generation task using the "gen4_image" model
  const task = await client.textToImage
    .create({
      model: 'gen4_image',
      ratio: '1920:1080',
      promptText: '@EiffelTower painted in the style of @StarryNight',
      referenceImages: [{
        uri: 'https://upload.wikimedia.org/wikipedia/commons/8/85/Tour_Eiffel_Wikimedia_Commons_(cropped).jpg',
        tag: 'EiffelTower'
      },
      {
        uri: 'https://upload.wikimedia.org/wikipedia/commons/thumb/e/ea/Van_Gogh_-_Starry_Night_-_Google_Art_Project.jpg/1513px-Van_Gogh_-_Starry_Night_-_Google_Art_Project.jpg',
        tag: 'StarryNight'
      }]
    })
    .waitForTaskOutput();

  console.log('Task complete:', task);
  console.log('Image URL:', task.output[0]);
} catch (error) {
  if (error instanceof TaskFailedError) {
    console.error('The image failed to generate.');
    console.error(error.taskDetails);
  } else {
    console.error(error);
  }
}

Python

from runwayml import RunwayML, TaskFailedError

client = RunwayML()

try:
  task = client.text_to_image.create(
    model='gen4_image',
    ratio='1920:1080',
    prompt_text='@EiffelTower painted in the style of @StarryNight',
    reference_images=[{
      'uri': 'https://upload.wikimedia.org/wikipedia/commons/8/85/Tour_Eiffel_Wikimedia_Commons_(cropped).jpg',
      'tag': 'EiffelTower',
    },
    {
      'uri': 'https://upload.wikimedia.org/wikipedia/commons/thumb/e/ea/Van_Gogh_-_Starry_Night_-_Google_Art_Project.jpg/1513px-Van_Gogh_-_Starry_Night_-_Google_Art_Project.jpg',
      'tag': 'StarryNight',
    }],
  ).wait_for_task_output()

  print('Task complete:', task)
  print('Image URL', task.output[0])
except TaskFailedError as e:
  print('The image failed to generate.')
  print(e.task_details)

Enterprise Scale

The Runway API has been used by the world’s largest consumer technology companies to reliably generate millions of videos for their users.

To request higher usage than the self-serve tiers, you can submit an exception request on the usage page of your developer portal.

Enterprise Benefits

In addition to higher rate limits, enterprise customers receive:

• Faster support via Slack (or email) channels
• Earliest access to new features
• Direct access to provide product feedback and request features
• Implementation and usage tips
• Custom payment terms
