Input

image1

*file

First input image

image2

file

Second input image, optional

prompt

string

Shift + Return to add a new line

A man img and a man img singing in the park together.A man img and a man img singing in the park together.

Input proper text prompts, such as "A woman img and a man img in the snow" or "A painting of a man img in the style of Van Gogh", where "img" specifies the token you want to augment and comes after the word.

Default: "A man img and a man img singing in the park together."

alpha

number

(minimum: 0, maximum: 1)

A smaller alpha aligns images with text better, but may deviate from the subject image. Increase alpha to improve identity preservation, decrease it for prompt consistency.

Default: 0.7

num_steps

integer

(minimum: 1, maximum: 300)

Number of diffusion steps

Default: 50

num_images_per_prompt

integer

(minimum: 1, maximum: 4)

Number of output images. Lower this setting if OOM.

Default: 1

guidance_scale

number

(minimum: 1.5, maximum: 50)

Scale for classifier-free guidance.

Default: 5

width

integer

Width of output image.

Default: 512

height

integer

Height of output image.

Default: 512

seed

integer

Random seed. Leave blank to randomize the seed.

Run this model in Node.js with one line of code:

npx create-replicate --model=cneural/fastcomposer-t4

or set up a project from scratch

Install Replicate’s Node.js client library:

npm install replicate

Set the REPLICATE_API_TOKEN environment variable:

export REPLICATE_API_TOKEN=<paste-your-token-here>

Find your API token in your account settings.

Import and set up the client:

import Replicate from "replicate";
import fs from "node:fs";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});

Run cneural/fastcomposer-t4 using Replicate’s API. Check out the model's schema for an overview of inputs and outputs.

const output = await replicate.run(
  "cneural/fastcomposer-t4:43938ee3abf4a5f1567e47ea410ce896d243a58f21c9981df0f811db0d189898",
  {
    input: {
      alpha: 0.7,
      width: 512,
      height: 512,
      prompt: "A man img and a man img singing in the park together.",
      num_steps: 50,
      guidance_scale: 5,
      num_images_per_prompt: 1
    }
  }
);

// To access the file URL:
console.log(output[0].url()); //=> "http://example.com"

// To write the file to disk:
fs.writeFile("my-image.png", output[0]);
